Answer:

Step-by-step explanation:

The original amount of cars is represented by 100%

Divide the cars sold by 70 to find 1% then multiply by 100 to calculate the number of cars the dealer had for sale, that is

number of cars = $\frac{21}{70}$ × 100 = 30

Select all of the equations that have graphs with the same y-intercept (starting amount).

attashe74 [19]

Answer: y=3x-8, y=5x-8, and y=2x-8

Step-by-step explanation:

These equations are all lines in slope-intercept form (y=mx+b where b is the y-intercept). y=3x-8, y=5x-8, and y=2x-8 all have -8 as the b value. Therefore, these equations have the same y-intercept.
