The points intercept at x= -7/5 and y=8/5
OlgaM077 [116]2 years ago
3 0

Answer:

x= negative 1 and 2/5 y=1 and 3/5

Step-by-step explanation:

1. Start by putting both equations into slope-intercept form.  (y=mx+b)

-3x+3y=9

-3x+3x+3y=9+3x

3y=9+3x

3y/3=9+3x/3

y=3+x

2x-7y=-14

2x-2x-7y=-14-2x

-7y=-14-2x

-7y/-7=-14/-7-2x/-7

y=2+2/7x

2. Graph the equations and find where they intercept.

Original price 32; markdown 12.5% what is the retail price
kobusy [5.1K]
Hello! The mark down is 12.5%, which means that will still have to pay a portion of the price. Mark down is a discount, where the price of the item goes down. To find the amount that needs to still be paid, subtract 12.5 from 100. 100 - 12.5 is 87.5 You still have to pay 87.5% of the price. Now, let's multiply that number by 32 to get the new price. 32 * 87.5% (0.875) is 28. There. The retail price is $28.
