Janie writes a polynomial expression using only one variable, x, with degree 3. Max writes a polynomial expression using only one variable, x, with degree 7.
What can you determine about the degree of the sum of Janie’s and Max’s polynomials?
What can you determine about the degree of the difference of Janie’s and Max’s polynomials?
Answer:
The sum of the polynomials is a 7th degree polynomial.
The difference of the polynomials is a 7th degree polynomial.
Step-by-step explanation:
Janie's polynomial is a 3rd degree with only x terms. Maybe she wrote:
f(x) = x^3
or maybe she was fancy and wrote:
f(x) =
x^3 + 2x^2 - 7x + 4
could be anything really, but the biggest exponent is 3.
Then Max does like:
g(x) = x^7
or
g(x) = x^7-x^4-3x+2
Whatever he made up, but the biggest exponent is 7.
So if they add or subtract their two polynomials, there's no x^7 in Janie's to add with the x^7 in Max's. MAYBE Max put some x^3 or x^2 or x or constants that might combine with the terms in Janie's.
Either way, anything that Max put in his polynomial that is a bigger power than 3 (4th, 5th, 6th, or 7th power) is just going to end up in the sum or difference.

16-2t=3/2t+9 solve for t
answer: t=2
steps:
16-2t = 3/2t+9
7 = 3/2t + 2t
2 is 4/2
7 = 3/2t + 4/2t
7 = 7/2t
7/2t = 7
(2/7)7/2t=7(2/7)
t=7(2/7)
t=2
Suppose a deposit of $ 2 , 000 in a savings account that paid an annual interest rate r (compounded yearly) is worth $ 2 , 209 after 2 years. using the formula a = p ( 1 + r ) t , we have 2 , 209 = 2 , 000 ( 1 + r ) 2 solve for r to find the annual interest rate (to the nearest tenth).
Answer:
5.1% (nearest tenth)
Step-by-step explanation:
Annual Compound Interest Formula
[tex]\large \text{$ \sf A=P\left(1+r\right)^{t} $}[/tex]
where:
A = final amountP = principal amountr = interest rate (in decimal form)t = time (in years)Given:
A = $2,209P = $2,000t = 2 yearsSubstitute the given values into the formula and solve for r:
[tex]\implies \sf 2209=2000\left(1+r\right)^{2}[/tex]
[tex]\implies \sf \dfrac{2209}{2000}=(1+r)^2[/tex]
[tex]\implies \sf 1.1045=(1+r)^2[/tex]
[tex]\implies \sf \sqrt{1.1045}=1+r[/tex]
[tex]\implies \sf r = \sqrt{1.1045}-1[/tex]
[tex]\implies \sf r = 0.05095194942...[/tex]
[tex]\implies \sf r = 5.095194942...\%[/tex]
Therefore, the annual interest rate is 5.1% (nearest tenth)

What number were both the numerator and denominator multiplied by to arrive at the equivalent fraction? What number were both the numerator and denominator multiplied by to arrive at the equivalent fraction ?
Answer:
Both the numerator and denominator should be multiplied by the same number to arrive at the equivalent fraction.
Step-by-step explanation:
Equivalent fractions = two or more than two fractions are said to be equal if both results the same fraction after simplification.
For example, consider the fraction 1/3
Multiplying numerator and denominator with 2, we get 1/3 × 2/2 = 2/6
Multiplying numerator and denominator with 3, we get 1/3 × 3/3 = 3/9
Multiplying numerator and denominator with 4, we get 1/3 × 4/4 = 4/12
Therefore, we can conclude that,
1/3 = 2/6 = 3/9 = 4/12 these are equivalent fractions.

You have two exponential functions. One function has the formula g(x) = 5x. The other function has the formula h(x) = 5-x. Which option below gives formula for k(x) = (g - h)(x)? k( x) = 10 x k( x) = 5 x - 5 -x k( x) = 2(5 x) k( x) = 5 x + 5 -x
The correct option is k(x) = 5x - (5-x)
What is Function?The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Here, the given functions are;
g(x) = 5x h(x) = 5 - x
Now,
k(x) = (g - h)(x)
k(x) = g(x) - h(x)
k(x) = 5x - (5 - x)
Thus, the correct option is k(x) = 5x - (5-x).

Given the image below, find the maximum value for z.
-3.5 < z < ___
I am so confused on how it's even possible to solve this
Answer:
-2.5 < x < 71
Step-by-step explanation:
I don't see a 'z' here, so I'll use x from the picture.
You would line up your values as such:
0 < 2x+5 < 71
You have a zero at the beginning because even without having an x value, your outcome would still be 5.
Subtract 5 from all sides.
-5 < 2x < 66
You now divide by two on both sides.
-2.5 < x < 33.
Which is your final answer.
You cannot go over 33, since 71 is your largest angle, and having something like say, 34, would give you 73.
-2.5 is your lowest value since if you went lower, you would have a negative angle, which isn't possible.

Answer:
x = -1; x = 5
Step-by-step explanation:
Standard Form of a Quadratic Function: f(x) = ax² + bx + c, where a ≠ 0
Given function: f(x) = x² - 4x - 5
⇒ a = 1, b = -4, c = -5
We are asked to solve the following function by factoring. In order to do so, let's rewrite the middle term by finding the factors that give a product of the first and last terms (a • c = -5) and give us the sum of the middle term (b = -4).
Factors that give a product of a • c: 1 • -5 = -5
Factors that give a sum of b: 1 + (-5) = -4
Step 1: Substitute f(x) = 0.
⇒ 0 = x² - 4x - 5
Step 2: Rewrite the equation with the factors.
⇒ 0 = x² + x - 5x - 5
Step 3: Factor out x and -5.
⇒ 0 = (x² + x) + (-5x - 5)
⇒ 0 x(x + 1) - 5(x + 1) [ Factor out the common factor. ]
⇒ 0 = (x - 5)(x + 1)
Step 4: Apply the Zero-Product Property (if m•n = 0, then m = 0 or n = 0)
a) 0 = x - 5 ⇒ 0 + 5 = x - 5 + 5 ⇒ 5 = x
b) 0 = x + 1 ⇒ 0 - 1 = x + 1 - 1 ⇒ -1 = x
Therefore, the missing solution for this quadratic function is x = 5.

Find the slope of every line that is parallel to the line on the graph.
Answer:
-1/5
Step-by-step explanation:
What are parallel lines?
Lines that are parallel never touch. They can extend infinitely and they will still never touch. In order for this to happen the slope of the two lines must be the same. So if we want to find the slope of every line that is parallel to the line on the graph, we simply find the slope of the line of the graph.
Finding the slope
We can find the slope using the following formula:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where the x and y values are derived from any given points on the line (x1,y1) and (x2,y2)
Here the given points are (-5,-1) and (0,-2)
So we have (x1,y1) = (-5,-1) meaning x1 = -5 and y1 = -1
We also have (x2,y2) = (0,-2) meaning x2 = 0 and y2 = -2
Now we plug these values into the formula
Recall formula : [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
==> Plug in x1 = -5 , y1 = -1 , x2 = 0 and y2 = -2
[tex]Slope=\frac{-2-(-1)}{0-5}[/tex]
==> simplify numerator and denominator
[tex]slope = \frac{1}{-5}[/tex]
So the slope of the line is -1/5
This means the slope of any parallel line to that line would also have a slope of -1/5

expand and simplify (2x+5)(3x+1`)
Answer:
6x^2 + 17x + 5
Step-by-step explanation:
(2x + 5)(3x + 1)
= 6x^2 + 2x + 15x + 5
= 6x^2 + 17x + 5
The expression (2x+5)(3x+1) is a product of two binomials. To expand this product, we multiply each term in the first binomial by each term in the second binomial, using the distributive property of multiplication.
When we multiply 2x by 3x, we get 6x^2.
Then we multiply 2x by 1, which gives us 2x.
Next, we multiply 5 by 3x, which gives us 15x.
Finally, we multiply 5 by 1, which gives us 5.
Putting these terms together gives us the expanded form of the expression:
(2x+5)(3x+1) = 6x^2 + 2x + 15x + 5
Simplifying, we can add the 2x and 15x terms to get 17x, giving us the final simplified expression:
(2x+5)(3x+1) = 6x^2 + 17x + 5.
