Answer:
m = - 3/4
Step-by-step explanation:
m = (7-4)/(0-4)
= 3/- 4
= - 3/4
You subtract the % that the sale is and take it away from 100%. You get 75% then take the original price and divide it by .75
-(z + (-17)) = 12 + 17
-(z - 17) = 12 + 17
Distribute -1:
-z + 17 = 12 + 17
Subtract 17 to both sides:
-z = 12
Multiply -1 to both sides:
z = -12
