Answer:
d
Step-by-step explanation:
132 = 1/2x + 2(x - 9)
132 = 1/2x + 2x - 18
132+ 18 = 2.5x
150 = 2.5x
150/2.5 = 60......price of adult ticket
a childs ticket is 9 less then adults......so 60 - 9 = 51 <== childs ticket
Answer:
(x + 3, y - 2)
Step-by-step explanation:
we know that
The rule of the transformation T is equal to
T: pre-image → image
T: (x, y) → (x',y')
T: (x, y) → (x - 3, y + 2)
so
x'=x-3 ----> x=x'+3
y'=y+2 ----> y=y'-2
The rule of the inverse of transformation T -1 is equal to
T-1: image → pre-image
T-1: (x', y') → (x,y)
T-1: (x', y') → (x'+3, y'-2)
You would obviously only be able to create two sandwiches with the given information.
