The best prediction for the number of customers is 5450.
To find this value, you just need to plug in 20 for x into the expression. Then, evaluate it using the order of operations.
8(20)^2 + 100(20) + 250
8(400) + 100(20) + 250
3200 + 2000 + 250
5450
Answer:
Cost of Amy's Phone= $191.75
Cost of Jill's phone = $191.75*2= $383.5
Step-by-step explanation:
let Amy's phone cost be A
Jill's phone cost = 2A
A/Q-
A +2A = $575.25
3A= $575.25
A=$575.25/3
A= $191.75
then,
Cost of Amy's Phone= $191.75
Cost of Jill's phone= $191.75*2= $383.5
Answer:
x = 8
Step-by-step explanation:
An undefined slope indicates that the line is vertical and parallel to the y- axis with equation
x = c ( c is the value of the x- coordinates the line passes through )
the line passes through (8, 4 ) with x- coordinate 8 , then
x = 8 ← equation of line
