Answer:
(-8, 2)
Step-by-step explanation:
set these equations equal to each other
1/2x + 6 = -3/4x -4
5/4 x = -10
x = -10x4/5 = -40/5 = -8
plug this x into one of the equations
y = 1/2 (-8) + 6
y = -4 + 6
y = 2
Oliver traveled 124.25 miles in 3.5 hours at a constant speed
Rate = 124.25 / 3.5 = 35.5 miles per hour (MPH)
The constant of proportionality is 35.5 miles per hour (MPH)
that's a tricky one!
but it is 7 i believe
i think 10?
