If f(x) = -2x - 3, find f(0) - 7. <br><br><br>help please!! I will give brainliest!!!!

VikaD [51]

Hi there!

$\huge\boxed{-10}$

f(x) = -2x - 3

Plug in 0 for "x" to solve for f(0):

f(0) = -2(0) - 3

f(0) = -3

Since the question is asking you to evaluate f(0) - 7, simply subtract:

-3 - 7 = -10.

F(x) = -7x2 + 9x - 15 and g(x) = -12x2 – 15x + 7

djyliett [7]

Answer:

${5x}^{2} + 6x = - 8$

Step-by-step explanation:

This question is asking you to insert two equations, f(x) and g(x), into the equation g(x) - f(x). This will lead to the equation below.

${ - 12x}^{2} - 15x + 7 - ({ - 7)x}^{2} + 9x - 15$

Now we can solve for the equation.

${ - 5x}^{2} - 6x - 8 = 0 \\ {5x}^{2} + 6x = - 8$
