Answer:
y=0, x=1
Step-by-step explanation:
6x-3y= -6 ...... equation 1
y =2x+2 ..... equation 2
subtract 2x from both sides
y-2x=2x-2x+2
y-2x=2
6x-3y= -6
y-2x=2
Rearrange
6x-3y= -6 ........x1
-2x +y=2............x3
6x-3y= -6
-6x +3y=2
0y=0
y=0
substitute y=0 in equation 1
6x-3xo= -6
6x= -6
x-6/6
x = -1
Absolute value of -2 is 2
absolute value of -3 is 3
so now the equation is 4 x 2 - 3
do 4 x 2 first = 8
now do 8 - 3 = 5
The answer is 6.27. Hope this helps.

Answer:
the maximum height of the ball is 81.125 feet above the ground. when the ball is at its peak, the ball is 156.25 feet away from home plate.
Step-by-step explanation:
x = d
y = h
to find the x coordinate of the vertex of a parabola, use the equation
x = -b/2a
y = ax^2 + bx+ c
y = – 0.0032x^2 + x + 3
x = -1 / 2 • - 0.0032
x = 156.25
plug x into original equation to find the the y coordinate of the vertex
y = – 0.0032 • (156.25)^2 + (156.25) + 3
y = – 0.0032 • 24414.0625 + 159.25
y = – 78.125 + 159.25
y = 81.125
