Answer:
Step-by-step explanation:
Gym A charges $ 9 per hr......1 hr = 60 minutes
9/60 = 0.15 per minute
Gym B charges 0.75 per 5 minutes

Answer:
D
Step-by-step explanation:
Since you start out with an initial amount and are adding each time, it would increase with a positive slope, left to right
Answer:
a = 9
Step-by-step explanation:
expand (y - 3)(y² + 3y + 9)
= y³ + 3y² + 9y - 3y² - 9y - 27
compare the coefficients of like terms with
y³ + 3y² + ay - 3y² - ay - 27
ay = 9y and - ay = - 9y ⇒ a = 9
5d + 10 - 4 = 13.50 <== ur equation
5d + 6 = 13.50
5d = 13.50 - 6
5d = 7.5
d = 7.5/5
d = 1.50 <== what each drink costs
