Answer:
Option c, d and e are equivalent expressions to 7x-14
Step-by-step explanation:
Which expressions are equivalent to 7x - 14
Equivalent Expressions:
The expressions that are the same, even if the expression looks different.
For example: 2x^2+4 is equivalent to 2(x^2+2) because solving 2(x^2+2) we get 2x^2+4
Now, finding equivalent to expressions 7x - 14
Option a) 14 - 7x
Not equivalent to 7x-14
Option b) x-2
Not equivalent to 7x-14
Option c) -(14 – 7x)
Simplifying: -14+7x so, equivalent to 7x-14
Option d) (x - 2)
Simplifying: 7x-14 so, equivalent to 7x-14
Option e) - 14 + 4x
Simplifying: 3x+4x-14 = 7x-14, so, equivalent to 7x-14
Option f) 2x - 10 + 5x + 4
Simplifying: 2x+5x-10+4 = 7x-6 so, Not equivalent to 7x-14
So, Option c, d and e are equivalent expressions to 7x-14

Answer:
X = 6
Step-by-step explanation:
17 - 5 = 12
12/2 = 6
hope this helps...
Answer:
6
Step-by-step explanation:
Find x
Try to get x by itself
2x + 5 = 17
subtract 5 on both sides
2×+5(-5)=17(-5)
by subtracting 5 from its opposite, it turns to 0
now we are left with
2x=12
Next we need to divide
2x is like 2(x) which is multiplication
the inverse is division
when we divide, whatever u do to one side u do to the other
2x/2=12/2
×=12/2
we finally got x by itself
we can break 12/2 even further by dividing and you'd get
×= 6

You lose 2 points every time you forget to write your name on a test. You have forgotten to write your name 4 times. What integer represents your change in points from forgetting to write your name?
Answer:
-8
Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.
how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.

Find the perimeter and the area
Answer:
Perimeter = 42 units Area = 57.73 square units
Step-by-step explanation:
Perimeter of an Astroid = 6l ---> 6 x 7 = 42 units
Area of an Astroid = (3 x pi x a^2)/8 = 57.73 square units
The path of a baseball thrown at an angle of 40 degrees can be modeled by y=-0.05x^2+3.2x+8y=−0.05x 2 +3.2x+8 where x is the horizontal distance in feet from the release point and y is the corresponding height, in feet. Calculate the average rate of change of the height over the interval 8\le x\le208≤x≤20.
Answer:
The average rate of change of the height [tex]A_{rate}=1.8[/tex]
Step-by-step explanation:
The average rate of change of a function is given by:
[tex]A_{rate}=\frac{f(b)-f(a)}{b-a}[/tex]
Where:
f(x) is the funtion, in our case [tex]f(x) = y = -0.05x^{2}+3.2x+8[/tex]
f(b) is the function evaluated in b, when b = 20
f(a) is the funtion evaluated in a, when a = 8
Let's find f(a) and f(b):
[tex]f(8) = -0.05(8)^{2}+3.2(8)+8=30.4[/tex]
[tex]f(20) = -0.05(20)^{2}+3.2(20)+8=52[/tex]
Therefore, using the average rate of change equation.
[tex]A_{rate}=\frac{52-30.4}{20-8}=1.8[/tex]
I hope it helps you!

Step-by-step explanation:
Write
0.189
as a fraction in simplest form.
Answer:
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
[tex]0.189 = \frac{189}{1000}[/tex]
Multiply to remove 3 decimal places. Here, you multiply top and bottom by = [tex]10^{3} = 1000[/tex]
[tex]\frac{0.189}{1} * \frac{1000}{1000} = \frac{189}{1000}[/tex]
In conclusion,
[tex]0.189 = \frac{189}{1000}[/tex]
the simplest form of [tex]\frac{189}{1000}[/tex] is [tex]\frac{189}{1000}[/tex] because
In order to simplify a fraction there must be:
1. A number that will divide evenly into both the numerator and denominator so it can be reduced. No such number exists for 189 and 1000.
or
2. The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number. 189 is not greater than 1000.
This fraction is in simplest form:
[tex]\frac{189}{1000}[/tex]

Find fg(x)
[tex]f(x) = {x}^{2} + 2[/tex]
[tex]g(x) = {x}^{2} + 6x + 11[/tex]
Answer:
f(g(x)) = x^4 + 12x^3 + 14x^2 -132x + 123
Step-by-step explanation:
Here, we simply will place g(x) into f(x)
So every x in f(x) is replaced by g(x)
Thus, we have;
(x^2 + 6x + 11)^2 + 2
= (x^2+6x-11)(x^2 + 6x -11) + 2
= x^4 + 6x^3 -11x^2 + 6x^3 + 36x^2 - 66x -11x^2 -66x + 121 + 2
= x^4 + 12x^3 + 14x^2 -132x + 123

Answer: a) (-4, -2)
cuz that's where the point intersects.
given that f (x)=x/2+5 find f(2)
Answer:
f(2) = 6
Step-by-step explanation:
Given that the function
[tex]f(x) = \frac{x}{2} + 5[/tex]
Put x=2
[tex]f(2) = \frac{2}{2} + 5 = 1 +5 = 6[/tex]
f(2) = 6
