Answer:
AB=8.94427191 (leave a comment if you need it rounded)
Step-by-step explanation:
First, plug these into the distance formula. (d= √(x2-x1)^2+(y2-y1)^2)
d=√(-3-5)^2+(4-8)^2
Now, solve the problem.
d=√(8)^2+(-4)^2
d=√64+16
d=√80
d=8.94427191

40 is 20% of 160, so if she saved 40$ and it was 20% off then the original price was 160$!!!
Answer:
y = 2
Step-by-step explanation:
Given
(y + 7) = 3(y - 1)
Multiply both sides by 3 to clear the fraction
y + 7 = 9(y - 1) ← distribute
y + 7 = 9y - 9 ( subtract 9y from both sides )
- 8y + 7 = - 9 ( subtract 7 from both sides )
- 8y = - 16 ( divide both sides by - 8 )
y = 2
