Answer:

f(g(-1)) = -3

Step-by-step explanation:

g(-1) = -1² - 7(-1) - 9

g(-1) = 1 + 7 - 9

g(-1) = 8 - 9

g(-1) = -1

f(g(-1)) = -1 - 2

f(g(-1)) = -3

tatuchka [14]

Answer:

the price for one pretzel was $1.75

Step-by-step explanation:

d for drinks

p for pretzel

3d + 3p = 9

3d = 9 -3p

d = 3 - p

replace d = 3 - 9 into 4d + 2p = 8.5

4d + 2p = 8.5

4(3 - p) + 2p = 8.5

12 - 4p + 2p = 8.5

-2p = 8.5 - 12

-2p = -3.5

p = 1.75
