Answer:
YEP
Step-by-step explanation:
Y=mx+b
m=slope
b=y intercept
perpendicuar lines have slopes that multiply to get -1
so
solving for y
add 4x both sides and divide by5 to get
y=4/5x+2
slope is 4/5
perpendicular means the slopes multiply to get -1
so
4/5 times what=-1?
what=-5/4
so
y=(-5/4)x+b
find b
given the point (-15,8)
8=(-5/4)(-15)+b
8=75/4+b
-43/4=b
y=(-5/4)x-43/4

Answer:
$708.87
Step-by-step explanation:
The price with tax included is ...
660.95 + 0.0725×660.95 = 660.95(1 +0.0725) = 708.87
