Answer: Brandon is 24, Michael is 72.
Step-by-step explanation:
Let m represent Michael
Let b represent Brandon
Then,
m = 3b <-----------"Michael is 3 times as old as Brandon."
m - 18 = 9(b - 18) <-----------"18 years ago, Michael was 9 times as old as Brandon."
3b - 18 = 9b - 162
-18 = 6b - 162
144 = 6b
Michael is 3 times as old as Brandon. Also, 18 years ago, Brandon would have been 6 and Michael would have been 54 meaning Michael was 9 times as old as Brandon 18 years ago.
V = by
Solve for b.
Divide both sides by y to isolate b.
b=
(-2,-8) is what I got after reflecting it off the y=x line.
Answer:
-71
Step-by-step explanation:
let 'n' = a number
2(143 + 2n) = 0n + 2
2(143 + 2n) = 2
143 + 2n = 1
2n = -142
n = -71
