Answer:
24
Step-by-step explanation:
f(x)=5x^2-7x
substitute x to 3
f(3)=5(3)^2-7(3)
f(3)=5(9)-21
f(3)=45-21
f(3)=24
Answer:
See attached picture
Step-by-step explanation:
This questions ask you to find g of f of x. This representation means to substitute f(x) = 1/x into the equation g(x).
g(f(x)) = (1/x) + 4.
The graph of this function is attached below.

Answer:
Simplifying
8x + 17 = 137
Reorder the terms:
17 + 8x = 137
Solving
17 + 8x = 137
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-17' to each side of the equation.
17 + -17 + 8x = 137 + -17
Combine like terms: 17 + -17 = 0
0 + 8x = 137 + -17
8x = 137 + -17
Combine like terms: 137 + -17 = 120
8x = 120
Divide each side by '8'.
x = 15
Simplifying
x = 15
