What is (f.g)(x)? f(x) = -2x + 3 g(x) = 2x Write your answer as a polynomial or a rational function in simplest form.​
Len [333]

Answer:

-4x +3

Step-by-step explanation:

Given the functions f(x) = -2x + 3 and g(x) = 2x We are to find the composite function (f*g(x))

(f*g(x)) = f(g(x))

f(g(x)) = f(2x)

f(2x) = -2(2x) + 3

f(2x) = -4x +3

Hence f(g(x)) = -4x +3

What is x-7=-16 and witch property of equality did you use to solve x
elena-14-01-66 [18.8K]

Answer: x = -9/ addition property of equality

Explanation: In this problem, we're given that x - 7 = -16 and we're asked to solve the equation and explain which equality we used.

The first statement we have will be

the given statement which is x - 7 = -16.

Now, we just solve the equation.

Our first and only step will be to add 7 to both sides.

Then, we find that x = -9.

The property we used here was the addition property of equality.

This property tells us that we can add the same quantity,

or equal quantities, to both sides of an equation.
