Step-by-step answer:

Given an enlargement from preimage (ABC) to image (A'B'C').

Need to find scale factor.

Solution:

Scale factor = linear size of image / linear size of preimage.

From the accompanying diagram, we see that

L(preimage) = AC = 4 units

L(image) = A'C' = 12 units

Therefore

Scale factor = L(image) / L(preimage) = 12 / 4 = 3

Rita will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs $0.90 per mil
Artemon [7]

Let M = #miles driven

 

Plan 1:   .50M + 70  = total cost

Plan 2    .70M = total cost

 

To know how far she would drive to have an equal cost for either plan just set the equations equal to each other

 

.70M = .50M + 70

 

subtract .50M from both sides

 

.20M = 70

 

M = 70/.20 = 350 miles

 

Check the answser:

 

Plan 1:  .50(350) + 70 = 175 + 70 = $245

Plan 2:  .7(350) = $245

they are equal so our answer checks as correct
