f(g(-1)) = - 3
Evaluate g(-1) and substitute into f(x)
g(-1) = (-1)² -7(-1) - 9 = 1 + 7 - 9 = - 1
f(g(-1)) = (-1) - 2 = - 3

Answer:
Chris gets £3000
Step-by-step explanation:
A : B : C
1 : 3 : 4 = 8 (add all the parts together)
£6000 ÷ 8 = 750
so the multiplier is x 750
1 : 3 : 4
↩ x 750
750 : 2250 : 3000

These are all linear equations, because all of the variables are raised to the positive FIRST power: <span>-4v+2w=7, x/4=y, x=-5
The last equation, </span><span>2/x +3/y=6, is not linear, because the powers of the variables are negative:
2x^(-1) + 3y^(-1) = 6 NON LINEAR</span>
