Answer:
y = 1/7x + 88/7
Step-by-step explanation:
y = mx +b
since it is perpendicular you have to get the negative reciprocal of the slope which is 1/7
y = 1/7x + b then you would plug in your points
12 = 1/7(-4) + b and then solve for b
12 = -4/7 + b
+ 4/7
88/7 = b
y = 1/7x + 88/7
Answer:
56.43
Step-by-step explanation:
52.25 + 4.18 (8% tax)
Let's look at the equation:
0.243x=117.369
Divide each side by 0.243.
X=483
So, the number is 483.
