Answer:
20
Step-by-step explanation:
16=1 2/10R + -8
16+8= 12/10R
24=12/10R
R=20
If you begin with the basic equation of a vertical parabola: y-k=a(x-h)^2, where (h,k) is the vertex, then that equation, when the vertex is (-3,-2), is
y + 2 = a (x + 3)^2. If we solve this for y, we get
y = a(x+3)^2 - 2. Thus, eliminate answers A and D. That leaves B, since B correctly shows (x+3)^2.

Answer: 66
Step-by-step explanation:
11 beats in 6 seconds means you mulitiply the beats times the seconds
Y= 10 + 1.25x
This is the answer because 10 is the initial fee (you start with it) and 1.25 is added for each minute, with each minute being the variable
