Answer:
8x - 7.
Step-by-step explanation:
f(x) = 2x - 5,
g(x) = 4x -1,
substituting g(x) as x in f(x),
f(g(x)) = 2(4x - 1) - 5
= 8x - 7
The correct answer is 2.8
Answer:
Solving with an equality is just simply the same as solving any algebra equations. If you were given a fraction, then just multiply both sides.
Example:
4 +
> 14
Subtract 4 on both sides:
4 - 4 +
> 14 - 4
> 10
Now <em>multiply both sides by 2</em>:
× 2 > 10 × 2
x > 20
