Answer:
what is your question there is no equation
820 + .06(820)
820 + 49.2
869.2
The cost of the car is $869.20.
<h3>Answer: 8x+3y = 16</h3>
============================
Work Shown:
x = number of hours spent running
8x = distance he runs (since he runs at 8 mph)
y = number of hours spent walking
3y = distance he walks (he walks at a speed of 3 mph)
8x+3y = total distance = 16 miles
8x+3y = 16
This equation is in standard form Ax+By = C
--------
Extra Info
Solving for y will get
8x+3y = 16
3y = -8x+16
y = (-8x+16)/3
y = (-8x)/3+16/3
y = (-8/3)x+16/3
This is in slope intercept form y = mx+b
m = -8/3 is the slope
b = 16/3 is the y intercept
Answer:
The formula to solve pi to get the area is 3.14r × 2 = Area
3.14 × (radius) × 2 = Area

notice the slope-intercept form, that's the y-coordinate.
