A. True (plug in 0 for x to confirm y=-1)
b. True
c. True
d. False (If you plug in 1 for x, y would equal -2, not 2.)
Well, it went from 400 to 550, so the difference is 150.
if we take 400 to be the 100%, what is 150 off of it in percentage?
15 because when you do the Pythagorean Therom 8squared plus the length squared equals 17squared so you get x squared equals 15
Ok the first box is 85 because that's the y - intercept or the constant in the equation because he starts with 85 wheels. The next box is 4 because that's the rate of change per a car. He's going to buy more wheels after there's 40 wheels so it's asking how many cars can you make with still 40 wheels left. The answer is 11 cars.
Slope intercept is y=mx+b
y=-1x-3
