Answer:
B. y - 2x = 5
Step-by-step explanation:
Add 2x to both sides, and the equation becomes, y = 2x + 5, as demonstrated from the graph.
3250 / 625 = 5.2
It will take 5.2 hours for the plane to travel 3250 miles.
9m+5=-13
9m=-18
m=-18/9
m=-2
Given the equation modeling Eva's height at time,t. To evaluate if she will reach height of 14 ft, we evaluate maximum height that she will reach.
At maximum height h'(t)=0
but
h(t)=-16t^2+20t+6
h'(t)=-32t+20=0
solving for t we get:
-32t=-20
t=20/32
t=5/8
thus the maximum height reached was:
h(5/8)=-16(5/8)^2+20(5/8)+6
h(5/8)=12.25 ft
Thus we conclude that she won't reach the height of 14 ft because her maximum height was 12.25 ft
