<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
Then y = -84
Hope I helped!
It's C.) and btw, L=10 and s=20
Hope this helps! :)
20 - 200 = -180...negative
Answer:
x = 7
Step-by-step explanation:
The vertical line x = 8 has an undefined slope.
For the line to be parallel to another line, it has to have the same slope.
x = 7 also has an undefined slope, and it is a vertical line. Therefore, it is parallel to line x = 8.
