Answer:
Y=2x+2
Step-by-step explanation:
Im not 100% sure this is correct but what I did was
Y=2(x-1)^2+6
2(x-1) = 2x -2
Y=2x -2^2 +6
Y=2x -4 + 6
-4 + 6 = 2
So y=2x+2 (y=mx+b)

Answer:
x = 15
Step-by-step explanation:
We need to find the value of x in the equation 3x – y = 18 when y = 27.
To find the value of x, put y = 27 in the above equation.
So,
3x - 27 = 18
3x = 45
x = 15
So, the value of x is 15.
Answer:
46.57
Step-by-step explanation:
Given that:
h(t) = 37t - 4.9t²
When the ball reaches the ground, then the height is zero;
So, we equate h(t) to zero and solve for t
37t - 4.9t² = 0
t = 0, 7.55
Let the Initial time be a = t = 0
The time the ball reaches the ground be b = 7.55
So, the average height can now be calculated as:
Average height =
=
=
=
= 46.57091665
≅ 46.57 to (2 decimal places)
