Answer:
-15 = n
Step-by-step explanation:
The train will have been traveling for 4 hours
train A=45,90,135, 180
train B=0,60,120,180
-4(x + 1) + 5 = 17
Distribute -4 inside the parentheses.
(-4x - 4) + 5 = 17
Combine like terms (-4 + 5).
-4x + 1 = 17
Subtract 1 from both sides.
-4x = 16
Divide both sides by -4.
x = -4
The first one is c , no proportional , slope is 35 and y intercept 19.
