Well since right now the average is 74.4, the tenth student would need to earn an 80 so the team got exactly an average of 75
Answer:
n = -14
Step-by-step explanation:
n/2 = -7
Multiply by 2 on both sides to isolate n
n = -7 x 2
n = -14
To graph
graph the point (3,6)
yintercept is on the y axis so go up 2 units from the origin and plot the point (0,2)
now the parabola
we know it has to go through points (3,6) and (0,2)
therefor we now that it opens down
we also knwo that the vertex's y value is the axis of symmetry
so we also put a point at (6,2)
draw a parabola opening down through the points (0,2) (3,6) (6,2), with (3,6) at the top/peak

Answer:
6, 1, 8, -16
Step-by-step explanation:
For each input we divide it by 2 and then add 3 to get the output:
6/2+3=3+3=6
-4/2+3=-2+3=1
For each output we subtract 3 and multiply it by two to get the input:
(7-3)*2=4*2=8
(-5-3)*2=-8*2=-16
