This is a very good question to know about. People who make tests really like it.
The way to solve it is to make the slower car stop and use the difference in speed = to the rate. then do it as an ordinary d = r*t problem.
The difference in speeds is 44 - 36 = 8 miles/ hour.
d = 260 miles
r = 8 mph
t = ???
t = d/r
t = 260/8
t = 32.5 hours.
Thats 32 1/2 hours.
Answer:
x^0 y^-3 / x^2 y^-1
= 1 / x^2 y^-1 (y^3) ...because x^0 = 1 and [(y^-1) (y^3)] = y^2
= 1/(x^2 y^2)
They are vertical angles meaning they both have the same angle thus you can set the two equations equal to each other
9y+7 = 2y+28
Solve for y
Plug your y into one of the equations and you’ll get your angle
Answer:
proportional graph is a straight line that always goes through the origin. A non-proportional graph is a straight line that does not go through the origin.
