Answer:

1) 14 2) 6 3) 53 4)-2

Step-by-step explanation:

1) 15 - n/7 = 13

7*15 - 7*n/7 = 7*13

105 - n = 91

-n = 91 - 105

-n = -14

n = 14

2) 44 = - 4 + 8p

-8p = - 4 - 44

-8p = -48

-p = - 48/8

-p = 6

3) 21 - h= -32

-h = -32 -21

-h = -53

h = 53

4) -19 = 11b + 3

-11b = 19 + 3

-11b = 22

-b = 22/11

-b = 2

b = -2

Verify if 1/2x-2 and g(x) = 2x + 4 are inverses

Triss [41]

They are inverses if f( (g(x)) = x

f((g(x)) = (1/2) (2x + 4) - 2 = x + 2 - 2 = x

so this proves that g(x) is the inverse of f(x)

the other inverse g((f(x)) should also be = x
