Answer:
-59
Step-by-step explanation:
f(x) = -2x - 7 and g(x) = -4x + 6.
f(g(x)) =
Replace x in the function f(x) with g(x)
= -2(-4x+6) -7
= 8x -12 -7
= 8x - 19
Let x = -5
f(g(-5) = 8(-5) -19
= -40 -19
= -59

Answer:The answer is 750
Step-by-step explanation:3885 of 750 can be written as:
3885/ 750
To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100
3885/750 × 100/100= (3885 × 100) over 750) × 1 over 100= 518/100
Therefore, the answer is 518%
If you are using a calculator, simply enter 3885÷750×100 which will give you 518 as the answer.
