Well, to solve, you would subtract 8 from both sides, which means x would end up equaling 32.
X=32
The van is traveling about 55.9 miles per hour.
X+y=4 y=3x
x+3x=4
4x=4
divide both sides by 4
x=1
Answer: y = 1/2x + 3
Step-by-step explanation:
Use the equation y=mx +b
Find the slope (m) of the line by finding the difference in y over the difference in x. Or "rise over run".
The y-intercept (b) is 3 (when x is zero, it is y).
