Answer:

2/3 changed to 5/3 because in the 2nd step, b was added to each side.  A number 1 is assumed in front of the b;

Step-by-step explanation:

Therefore, 2/3 becomes 5/3 because 2/3 + 1 = 1 2/3 = 5/3.  I just simplified.

First find midpoint:  \left( \frac{-1+5}{2}, \frac{6+5}{2}\right) = (2, 5.5) 

Find slope of line that passes through R and S:    slope = \frac{6-5}{-1-5} = \frac{-1}{6}   

Negative reciprocal of slope to get slope of perpendicular:    new slope = 6

Line will be:  y-5.5=6(x-2) 

  y = 6x - 6.5

kiruha [24]

The discount amount would be $1470.00

the new cost of the car would be $19530.00

For given question,

A car dealer gave a 7% discount to the first 50 people through the door.

the car you are interested in cost $21,000.00

We need to find the discount amount and the new price of the car.

A car dealer gave a 7% discount.

this means, to find the discount amount, we need to find the 7 percent of $21,000.00

⇒ discount amount = 7 percent of $21,000.00

⇒ discount amount = (7 / 100) × 21,000.00

⇒ discount amount = $1470.00

So, the new price of the car would be,

the new price of the car = original price - discount amount

⇒ the new price of the car = $21,000.00 - $1470.00

⇒ the new price of the car = $19530.00

Therefore, the discount amount would be $1470.00

the new cost of the car would be $19530.00
