f(x) = x² + 7

g(x) = -3x + 1

h(x) = 12/x

j(x) = 2x + 9

a.  g(10) = -3(10) + 1 = -20

b. f(3) = 3² + 7 = 9 + 7 = 16

c. h(-2) = 12/(-2) = -6

d. j(7) = 2(7) + 9 = 23

e. h(a) = 12/a

f. g(b+c) = -3(b+c) + 1 = -3b - 3c + 1

g. f(h(x)) = f(12/x) = (12/x)² + 7 = 7 + 144/x²

h. 16 = g(x) = -3x + 1,    -3x = 15,   x = -5

i. -2 = h(x) = 12/x,    x = 12/(-2),  x = -6

j.  23 = f(x) = x²+7,   16=x²,   x=±4

Oksana_A [137]
7 - 9w = - 29

Subtract 7 from both sides

- 9w = - 36

Divide by - 9 on both sides

w = 4
