Let's give some distances
100 up 100 flat 100 down meters
then return 100 up 100 flat 100 down
time required (distance/rate = time ) 200/100 + 200/120 + 200 / 150 = 5 hr
distance 600
distance / time = average speed = 600/5 = 120 m/s
We have an isosceles triangle with one angle 54 degrees and the other angles both labeled y degrees.
Triangle angles add to 180 degrees.
54 + y + y = 180
54 + 2y = 180
2y = 180 - 54 = 126
y = 126/2 = 63 degrees
Answer: 63 degrees
Check: 63+63+54=180 good
Answer:
y = 4x + 2
Step-by-step explanation:
This is the formula: 
y - 2 = 4(x - 0) (distribute the 4)
y - 2 = 4x (add 2 on both sides)
y = 4x + 2
