Answer:
f(− 3) = 84
Step-by-step explanation:
Given the function, f(x) = 7(9 − x), to find the value of f(-3) substitute x = -3 into the function:
f(− 3) = 7(9 − (− 3))
f(− 3) = 7(9 + 3)
f(− 3) = 7(12)
f(− 3) = 84
Therefore, f(− 3) = 84.

Answer:
x = 8/9
Step-by-step explanation:
-4(2x-3) + 4x = 9x -4x +8 -4
2x*(-4) -3*(-4) + 4x = 9x - 4x + 8 - 4
-8x + 12 + 4x = 9x - 4x + 8 - 4 {Combine like terms}
-4x + 12 = 5x + 4
12 = 5x + 4x + 4
12 = 9x + 4
12- 4 = 9x
9x = 8
x = 8/9
Answer:
The answer would be A.
Step-by-step explanation:
Sorry if the answer is wrong.
Answer:
Your first step should be to separate the x's and the numbers.
This is how I would do it:
-3x+2-5x-7=4x+2
-3x-5x-4x=2-2+7
-12x=7
x=-7/12
