Answer: The correct answer is Choice C.
Step-by-step explanation: The cost of the ride is .50 per mile, plus $3.00 for each ride. In order to calculate it, the correct formula is going to multiply the number of miles, represented by x, by .50, and then add $3 for the ride.
Choice C is doing just that. $.50x + $3
The predicted value of y = 25
y = 3(5) + 10
= 15 + 10
= 25

Answer:
(4,12)
(-1,-3)
Step-by-step explanation:
x^2 - y = 4
y = 3x
Use substitution. Substitute 3x for y in the first equation
x^2 - (3x) = 4
x^2 -3x =4
Subtract 4 from each side
x^2 -3x -4 = 4-4
x^2 -3x-4 =0
Factor
(x-4) (x+1) =0
Using the zero product property
x-4 =0 x+1 =0
x=4 x=-1
Now to find y for each x solution
x=4
y =3x = 3(4) =12
(4,12)
x=-1
y =3x = 3(-1) =-3
(-1,-3)
