Answer :
[tex]8x+4y=48 \\ -8x-8x \\ 4y=-8x+48 \\ /4 /4 \\ y=-2x+12[/tex]
B=0.10x + 2
B=0.10x + 2
Slope - intercept form: y = mx + b
8x + 4y = 48
8x - 8x + 4y = 48 - 8x
4y = -8x + 48
4 4
y = -2x + 12
Answer: y = -2x + 12
First you subtract 8x on both sides to get 4y alone giving you 4y = -8x + 48. Then you divide by 4 on both sides to get y alone which leaves you with y = -2x + 12
Question 6.6
Answer: B = 0.10x + 2
8x + 4y = 48
8x - 8x + 4y = 48 - 8x
4y = -8x + 48
4 4
y = -2x + 12
Answer: y = -2x + 12
First you subtract 8x on both sides to get 4y alone giving you 4y = -8x + 48. Then you divide by 4 on both sides to get y alone which leaves you with y = -2x + 12
