3(-2x+6) -x+3=0
-6x+18-x+3=0
-7x+21=0
-7x=-21
x=3
y=-2x+6
y=-2(3)+6
=6-6
=0

I think it’s proportional!
Answer:
midpoint: (7.5, 1.5)
Step-by-step explanation:
midpoint formula: ( (x1 + x2)/2 , (y1 + y2)/2 )
x1= 10
x2= 5
y1=1
y2=2
( 10 + 5 )/2 = 7.5
( 1 + 2 )/2 = 1.5
midpoint coordinates => ( 7.5 , 1.5 )
Axis of symmetry shows the min/max. its a max in this case and its at t=1.5
so the ans is <span>t = 1.5; it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground</span>
