1. bobby would be 21 and chris 18.
8^15 ÷ 1/8^3 = 8^15 x 8^3=8^18
I’m pretty sure this is right:
Answer:
y = 2
Step-by-step explanation:
Addition Method:
4x - 2y = 6
2x + y = 7
-2(2x + y) = -2(7)
4x - 2y = 6
-4x - 2y = -14
-4y = -8
y = 2
Substitution Method:
4x - 2y = 6
2x + y = 7
-2y = 6 - 4x
2y = 4x - 6
y = 2x - 3
2x + (2x - 3) = 7
4x - 3 = 7
4x = 10
x = 2.5
2(2.5) + y = 7
5 + y = 7
y = 2
Brainliest, please :)

Step-by-step explanation:
(a) Clockwise rotation moves a point from (x, y) to (y, -x).
__
(b) Reflection across x=1 moves a point from (x, y) to (2-x, y).
