Y=65+40x, i believe this is it im not to sure
Answer:
x = 23/9
y = 1/9
Step-by-step explanation:
2x - y + y - 5 = 5 + y - 5
2x - 5 = y
3x + 3(2x - 5) = 8
3x + 6x - 15 = 8
9x/9 = 23/9
x = 23/9
2x - 5 = y
2(23/9) - 5 = y
46/9 - 5 = y
1/9 = y
Answer:
-2≤y≤5
Step-by-step explanation:
Answer:
<em>100feet</em>
Step-by-step explanation:
Given the height of the object modelled by the equation
y = -16x^2 + 48x + 64
We can find the maximum height reached by the object since we are not told what to find.
The velocity of the object at its max height is zero.
dy/x = 0
dy/dx = -32x + 48
0 = -32x + 48
32x = 48
x = 48/32
x = 1.5secs
get the max height by substituting x = 1.5 into the given equation:
y = -16x^2 + 48x + 64
y = -16(1.5)^2 + 48(1.5)+ 64
y = -36+72+64
<em>y = 100 feet</em>
<em>Hence the maximum height reached by the object is 100feet</em>
