Answer:
for a year it would be 90 dollars i think and for the second year i think it would be 30 because a year is 12 months and every month they take away 5 so 12x5 is 60 so 150 minus 60 is 90 and for the second year 90 minus 60 is 30

Answer: The scale is 5/4
Step-by-step explanation:
To determine the scale factor, you have to locate which sides are similar to each other .
the side length with 20 is congruent to 16
15 is similar to 12 and 10 is similar to 8.
And to get from triangle A to triangle B of any side length, we need to multiply by a certain number which is the scale factor.
And to find that number we will divide the side length of any side in triangle A by the similar side to it in triangle B.
20/ 16 = 5/4
15/ 12 = 5 / 4
10 / 8 = 5/4
Check the picture below.
the left and right are just two rectangles of 5x * 2x
the front and back are just two rectangles of 3x * 5x
the top and bottom are also two rectangles of 3x * 2x
since the area of a rectangle is just width * length then,
The x values range from -6 to 6, *including* those two numbers, so the domain is [-6, 6], and the y values range from -2 to 2, also inclusively, so the range is [-2, 2]
