The value of the function [tex]f(x)=3x^{2} -2x[/tex] for x=4 is 40.
The given function is [tex]f(x)=3x^{2} -2x[/tex].
We need to evaluate the given function for x=4.
What is the function?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
To find the value of the given function replace x with 4 and simplify.
That is, [tex]f(4)=3(4)^{2} -2 \times 4=48-8=40[/tex].
Hence, the value of the function [tex]f(x)=3x^{2} -2x[/tex] for x=4 is 40.

Answer: x = 12
Step-by-step explanation: The given triangle is an equilateral triangle. Equilateral triangles have all angles and all sides equal. Thus, let's solve for x knowing all 3 equations are equal. For this, only 2 equations are necessary.
5x - 22 = 4x - 10
Adding 22 to both sides, we get:
5x = 4x + 12
Subtracting 4x to 5x, we get:
x = 12.
Thus 5*12 - 22 = 38, and 4*12 - 10 = 38, and so is 3*12 + 2 = 38. Thus, we know this is correct.
Answer:
x = 12
Step-by-step explanation:
Hello!
All three angles are congruent, indicating that this is an equilateral triangle.
The rules of this triangle say that all sides are congruent.
We can solve for x by setting any 2 sides equal to each other. I'm picking AB and BC.
Solve for x4x - 10 = 3x + 24x - 3x - 10 = 2x - 10 = 2x = 12The value of x is 12.

Hi, so I know the answer to this problem (now that I got it wrong) but I'm not quite sure why I was wrong, help?
Answer:
[tex]-2x^2-x[/tex]. Your answer was wrong because "x-squared" terms didn't cancel.
Step-by-step explanation:
To solve this problem, set up an equation. We know something is supposed to be added to the expression [tex]2x^2+2x[/tex], and the result should be x. So:
[tex]2x^2+2x+(\text{ ? })=x[/tex]
We want to solve for the question mark... the unknown thing that we're adding to the original expression, in order to get x.
It is uncommon to put question marks in equations to represent quantities. Usually we use a letter. Since x is already being used in the equation, we should pick something else ... we could use "y".
[tex]2x^2+2x+(\text{ } y \text{ })=x[/tex]
...or just...
[tex]2x^2+2x+y=x[/tex]
Algebra allows us to solve the equation and find out what "y" is equivalent to.
To solve, we want to get the "y" by itself. To do so, we try to eliminate the other "terms" from the left side of the equation.
Understanding "terms" & "like terms"
Terms
"Terms" in an equation are either a number multiplied to other things, or just a single number that isn't multiplied to anything else.
For example, the various terms in our equation above are
[tex]2x^2[/tex], [tex]2x[/tex], [tex]y[/tex], [tex]x[/tex]
You might ask why the last things, which don't have a number, are considered terms.
Remember that multiplying by 1 doesn't change anything, so we could imagine each of the last two terms as being 1 times the letter.
So, we can rewrite our equation:
[tex]2x^2+2x+1y=1x[/tex]
Like terms
"Like terms" are terms where the "other stuff the numbers are multiplied to" is the same, so for instance, the [tex]2x[/tex] and the [tex]1x[/tex] are like terms. They are like terms because, the "other stuff" that the numbers are multiplied to are "x" for both terms. Note that [tex]2x[/tex] and [tex]2x^2[/tex] are not "like terms" because the "stuff" is different:
[tex]x[/tex] is different than [tex]x^2[/tex]
"Like terms" are important because only like terms can be "combined" into a single simplified term.
Solving equations
To solve an equation, we isolate what we're solving for, y, by disconnecting the other terms from it, and simplify.
Starting with subtracting 2x from both sides of the equation:
[tex]2x^2+2x+1y=1x\\(2x^2+2x+1y)-2x=(1x)-2x[/tex]
Subtraction is the same as "adding a negative":
[tex]2x^2+2x+1y+(-2x)=1x+(-2x)[/tex]
Since all terms are now connected by addition, we can add in any order we want (because of the Commutative Property of Addition), and we can combine like terms.
Thinking just about the number parts, since [tex]1+(-2)=-1[/tex], then [tex]1x+(-2x)=-1x[/tex].
Returning to our main equation, the right side simplifies:
[tex]2x^2+2x+1y+(-2x)=1x+(-2x)\\2x^2+2x+1y+(-2x)=-1x[/tex]
On the left side: [tex]2x[/tex] and [tex]-2x[/tex] are like terms.
Fact: [tex]2+(-2)=0[/tex]
So, [tex]2x+(-2x)=0x[/tex]
Since anything times zero is just zero, [tex]0x=0[/tex]. Furthermore, adding zero to anything doesn't change it. So when the [tex]2x[/tex] and [tex]-2x[/tex] terms on the left side of our main equation are combined, they "disappear" (While we talked through are a lot of rules/steps to justify why that works, it is common to omit those justifications, and to just combine those like terms and make them disappear.)
So, [tex]2x^2+2x+1y+(-2x)=-1x[/tex] simplifies to:
[tex]2x^2+1y=-1x[/tex]
Similarly for the [tex]2x^2[/tex] term, we subtract from both sides:
[tex]2x^2+1y=-1x\\(2x^2+1y)-2x^2=(-1x)-2x^2\\2x^2+1y+(-2x^2)=-1x+(-2x^2)[/tex]
Combining like terms on the left, they disappear.
[tex]1y=-1x+(-2x^2)[/tex]
There are no like terms on the right.
Since the two terms on the right are added together, we can use the commutative property of addition to rearrange:
[tex]1y=-2x^2+(-1x)[/tex]
Addition of a negative can turn back into subtraction, and simplify multiplication by 1.
[tex]y=-2x^2-x[/tex]
Remembering we chose "y" as the unknown thing we wanted to know, that's why the "correct answer" is what it is.
Verifying an answer
Verifying can double check an answer, and helps explain why the answer you chose doesn't work.
To verify an answer, the original statement said add something to the expression and get a result of "x". So, let's see if the "correct answer" does:
[tex]2x^2+2x+(\text{ } ? \text{ })\\2x^2+2x+(-2x^2-x)\\2x^2+2x+(-2x^2-1x)\\2x^2+2x+(-2x^2)+(-1x)[/tex]
Combining the "x-squared" terms, completely cancels...
[tex]2x+(-1x)[/tex]
Combining the "x" terms, and simplifying...
[tex]1x\\x[/tex]
So it works.
Why isn't the answer what you chose:
[tex]2x^2+2x+(\text{ } ? \text{ })\\2x^2+2x+(-x^2-x)\\2x^2+2x+(-1x^2-1x)\\2x^2+2x+(-1x^2)+(-1x)[/tex]
Combining the x-squared terms, things don't completely cancel...
[tex]1x^2+2x+(-1x)[/tex]
Combining the x terms...
[tex]1x^2+1x\\x^2+x[/tex]
So adding the answer that you chose to the expression would not give a result of "x", which is why it is "wrong"

Find the nth term of this number sequence
1, 7, 13, 19, ...
Answer:
6n-5
Step-by-step explanation:
Some different types of sequences
To find sequence patterns, often the sequences are arithmetic (adding by a constant amount) or geometric (multiplying by a constant amount).
To test if something is a geometric sequence, find the quotient of (divide) adjacent terms.
To test if something is an arithmetic sequence, find the difference of (subtract) adjacent terms.
Finding the type of our sequence
Note the following:
19-13=6
13-7=6
7-1=6
So, to get each next term, add 6. However, what is the nth term?
Finding an expression for our sequence
You'll be adding up "n" sixes to get there (expressed with multiplication, because multiplication is shorthand for repeated addition), but we need a starting point so that when n=1, the expression equals 1, and when n=2, the expression equals 7... and so on. This starting point shifts the "6n" piece of our expression so that it lines up on the sequence. I'm going to call this starting point "b" for the base that is supporting this sequence.
So the expression will look something like [tex]6n+b[/tex]
Knowing that the expression needs to equal 1 when n=1, we can set up an equation and solve for "b".
[tex]6n+b=n^{\text{th}} \text{ term}\\6(1)+b=(1)\\6+b=1\\(6+b)-6=(1)-6\\b=-5[/tex]
So, the expression for the nth term of the sequence is [tex]6n-5[/tex]
Verifying
To verify that the expression we found is right, we can test our expression for each of the terms we do know:
The first term (n=1) is 1
[tex]6n+b=n^{\text{th}} \text{ term}\\[/tex]
[tex]6(1)-5 \overset{?}{=} (1)[/tex]
[tex]6-5 \overset{?}{=} 1[/tex]
[tex]1 \overset{\checkmark}{=} 1[/tex]
The second term (n=2) is 7
[tex]6n+b=n^{\text{th}} \text{ term}\\[/tex]
[tex]6(2)-5 \overset{?}{=} (7)[/tex]
[tex]12-5 \overset{?}{=} 7[/tex]
[tex]7 \overset{\checkmark}{=} 7[/tex]
The third term (n=3) is 13
[tex]6n+b=n^{\text{th}} \text{ term}\\[/tex]
[tex]6(3)-5 \overset{?}{=} (13)[/tex]
[tex]18-5 \overset{?}{=} 13[/tex]
[tex]13 \overset{\checkmark}{=} 13[/tex]
The fourth term (n=4) is 19
[tex]6n+b=n^{\text{th}} \text{ term}\\[/tex]

Subtract [tex]5/6[/tex] from both sides:
[tex]\frac{2}{3}x+\frac{5}{6}-\frac{5}{6}=\frac{10}{3}-\frac{5}{6}[/tex]
Combine the fractions:
[tex]\frac{2}{3}\cdot x+\frac{5-5}{6}=\frac{10}{3}-\frac{5}{6}[/tex]
Combine the numerators:
[tex]\frac{2}{3}\cdot x+\frac{0}{6}=\frac{10}{3}-\frac{5}{6}[/tex]
Reduce the zero numerator:
[tex]\frac{2}{3}\cdot x+0=\frac{10}{3}-\frac{5}{6}[/tex]
Simplify the arithmetic:
[tex]\frac{2}{3}\cdot x=\frac{10}{3}-\frac{5}{6}[/tex]
Find the lowest common denominator:
[tex]\frac{2}{3}\cdot x=\frac{10\cdot 2}{3\cdot 2}+\frac{-5}{6}[/tex]
Multiply the denominators:
[tex]\frac{2}{3}\cdot x=\frac{10\cdot 2}{6}+\frac{-5}{6}[/tex]
Multiply the numerators:
[tex]\frac{2}{3}\cdot x=\frac{20}{6}+\frac{-5}{6}[/tex]
Combine the fractions:
[tex]\frac{2}{3}\cdot x=\frac{20-5}{6}[/tex]
Combine the numerators:
[tex]\frac{2}{3}\cdot x=\frac{15}{6}[/tex]
Find the greatest common factor of the numerator and denominator:
[tex]\frac{2}{3}\cdot x=\frac{5\cdot 3}{2\cdot 3}[/tex]
Factor out and cancel the greatest common factor:
[tex]\frac{2}{3}\cdot x=\frac{5}{2}[/tex]
2. Isolate the x
[tex]\frac{2}{3}\cdot x=\frac{5}{2}[/tex]

Why learn this
Linear equations cannot tell you the future, but they can give you a good idea of what to expect so you can plan ahead. How long will it take you to fill your swimming pool? How much money will you earn during summer break? What are the quantities you need for your favorite recipe to make enough for all your friends?
Linear equations explain some of the relationships between what we know and what we want to know and can help us solve a wide range of problems we might encounter in our everyday lives.

Step-by-step explanation: i took the test (sorrry i cant tell why, im bad at explaining)
i need help with my math :( im horrable with it i cant do divideing fractions nor multiply and i dont know most of my multiples can anyone help im going into 7th
Step-by-step explanation:
To multiply the fractions, like
[tex] \frac{1}{4} \times \frac{1}{9} [/tex]
Multiply the top,
then multiply the bottom.
[tex] \frac{1}{4} \times \frac{1}{9} = \frac{1 \times 1}{4 \times 9} = \frac{1}{36} [/tex]
Try to use a calculator if you aren't arithmetic heavy, but I suggest you to try to remember them because they are going to be helpful for courses like Algebra, Calculus, Statistics, etc.
To divide fractions, like
[tex] \frac{ \frac{1}{5} }{ \frac{1}{8} } [/tex]
You take the top number,
[tex] \frac{1}{5} [/tex]
Then you flip the bottom number,
[tex] \frac{8}{1} [/tex]
Then multiply the two
[tex] \frac{1}{5} \times \frac{8}{1} = \frac{8}{5} [/tex]
And that is your answer. Comment if you need more clarification

A triangle is shown with its exterior angles. The interior angles of the triangle are angles 2, 3, 5. The exterior angle at angle 2 is angle 1. The exterior angle at angle 3 is angle 4. The exterior angle at angle 5 is angle 6. Which statements are always true regarding the diagram? Select three options. m∠5 + m∠3 = m∠4 m∠3 + m∠4 + m∠5 = 180° m∠5 + m∠6 =180° m∠2 + m∠3 = m∠6 m∠2 + m∠3 + m∠5 = 180°A triangle is shown with its exterior angles. The interior angles of the triangle are angles 2, 3, 5. The exterior angle at angle 2 is angle 1. The exterior angle at angle 3 is angle 4. The exterior angle at angle 5 is angle 6. Which statements are always true regarding the diagram? Select three options. m∠5 + m∠3 = m∠4 m∠3 + m∠4 + m∠5 = 180° m∠5 + m∠6 =180° m∠2 + m∠3 = m∠6 m∠2 + m∠3 + m∠5 = 180°
Answer:
In the given Triangle problem, the three options are:
1. m∠5 + m∠6 = 180°
2. ∠2+ ∠3 = ∠6
3. m∠2 + m∠3 + m∠5 = 180°
Step-by-step explanation:
Concept: Consider Δ ABC with Exterior angles ∠1, ∠4 and ∠6.
Use the Exterior angle Property of Triangle which says that an exterior angle of a triangle is equal to the sum of the opposite interior angles.
For Exterior angle ∠1 we have:
∠1 = ∠5 + ∠3
Similarly, for Exterior ∠4 we have:
∠4 = ∠5 + ∠2
Similarly, for Exterior ∠6 we have:
∠6 = ∠2 + ∠3
Now, use the Triangle Sum Property which states that in a triangle sum of the measures of angles is equal to 180°
m∠2 + m∠3 + m∠5 = 180°
Linear Pair:
The measure of a straight angle is 180°, so a linear pair of angles must add up to 180°.
m∠5 + m∠6 = 180°
