Aviolin was on sale for 50% off. the sale price is $ 50. what was the original price?

bueno... el 50 porciento de 100 es 50 asi que el precio original es 100

The original price was $100

Step-by-step explanation:

50 + 50%= 100

100 - 50 = 50

50 is half or 50% of 100

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

4+4+2x

or

2x+8
