690 because 86 is rounded up to 90
Answer:
y=1/8x+1.25
Step-by-step explanation:
Since it's perpendicular change the slope to the opposite
You have the slope so plug it into the equation y-y1=m(x-x1)
y-(1)=(1/8)(x--2)
Let the number of units sold be n
Revenue = 65*n
Cost function = 5500 +4*n
Profit function = Revenue - Cost
=65n -(5500+4n)
61n-5500
Six women push grocery carts up a ramp as shown.
2 carts weigh 50 lbs. each.
4 carts weigh 20 lbs. each.

X varies directly with y means x=ky
k is the constant of variation
given when x=32 and y=8
32=8k
divide by 8
4=k
so
x=4y
when y=44
x=4(44)
x=176
x=176 when y=44
