Let’s say you pay $70 per month for digital cable television. Your cable company offers pay per view movies for $3 per movie. Write a function that models the total cost of your cable bill.
1. f(x) = 70 + 3x
2. 3x + y = 70
3. y = 70/3x

Write a function for the situation: It cost $5.00 to enter the theme park and $2.00 for each ride.
1. y = 5/2x
2. f(x) = 5(2x)
3. f(x) = 5 + 2x

Determine the average rate of change of f(x) = x2 + 1 from x = 0 to x = 3.

Use the diagram below to find the angles of x and y.
(Picture: Image 2)
1. y = 105 degrees and x = 75 degrees
2. y = 105 degrees and x = 65 degrees
3. y = 150 degrees and x = 75 degrees

In the diagram below, each of the two angles shown have two sides that are congruent and point C and F have the same angle, are the two triangles congruent?

1. yes
2. no

Thank you so, so much if you help! I'm dumb and can't figure this stuff out
