Answer:
The equation of the line in slope-intercept form is y = 2x + 6.
Answer:
3, 5
Step-by-step explanation:
Looking at the graph, the x-intercepts are -5, -3, 1 and 5.
Hence the graph equation is (x+5)(x+3)(x-1)(x-5)
I believe the answer is 21. I can tell you how I got the answer if you want.
Answer:
A'(-4,-3)
Step-by-step explanation:
use formula of reflection over y axis
(x,y)=(-x,y)
A(4,-3)=A'(-4,-3)
The ball hits the ground when the height h(t) = 0 , so
-16t^2 + 80t = 0
-16t(t - 5) = 0
t- 5 = 0 or -16t^2 = 0 ( here t = 0 which corresponds to when ball is thrown)
t - 5 = 0 gives:-
t = 5 seconds (answer)
