Last year's computer models are discounted 20%. what was the original price to the nearest dollar of a computer that now cost $1480?

$1850.

Step-by-step explanation:

If the original price was $ x, then

x - 0.20x  = 1480

0.8x = 1480

x = 1480 / 0.8

x = 1850 dollars.

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

b
