Answer:
^3 divided by 512 goes to ^3 divided by 8x8x8
8^2 goes to ^2 divided by 8x8x8
Step-by-step explanation:
4x+7y=47 /*4 ------>16x + 28y=188
5x-4y=-5 /*7 -------->35x-28y=-35
16x + 28y=188, add this two equations
35x-28y=-35
16x + 28y+35x-28y=188-35
16x +35x=188-35
51x =153m
x=3
5x-4y=-5
5*3-4y=-5
15-4y=-5
4y=15+5
4y=20
y=5
Answer (3,5), B
Obtaining thevslope you get 6/5. so
9=-24/5 +n
=
y=6/5x + 21/5
