Just sketch two lines crossing each other like a street intersection.
h = -4.9t^2 + vt
In our problem,
v = 12
t = 2
Let's plug our numbers into the equation.
h = -4.9(2)^2 + (12)(2)
h = -19.6 + 24
h = 4.4 m
I think it’s C
I hope it’s right
Answer: M =
Step-by-step explanation:

M (x + y) + 4y = x + 2y (Multiply
in both sides)
M (x + y) = x + 2y - 4y
M (x + y) = x - 2y (Divide (x+y) from both sides)
M =
Do you what the T,r and s stand for?
