he field follows the path modeled by the equation h = 8t + 20. Let t be the time since the ball is hit and h be the height. What do the intersection points of the equations represent?
A. the height when the ball and the bird are the same distance across the field
B. the height when the ball is hit and the bird starts flying across the field
C. the time when the height of the ball and the bird are the same

Answer:

Options: 1, 4 & 6

Step-by-step explanation:

Yes:

1. -1(x-1)^{2} +9=-1(x^{2} -2x+1)+9=-x^{2} +2x-1+9=-x^{2} +2x+8

4. -x^{2} +2x+8

6. (x+2)(4-x)=2x-x^{2} +8=-x^{2} +2x+8

No:

2. -(x-9)^{2} +1=-(x^{2} -18x+81)+1=-x^{2} +18x+81+1=-x^{2} +18x+82

3. x^{2} +2x-8

5. (x+2)(x-4)=x^{2} -2x-8

Hope this helps

Solve the equation for y 5x-7y=10
leva [86]

Answer:

y = 5x/7 + 10/-7

Step-by-step explanation:

subtract 5x from both side and you should get -7y = -5x + 10

divide negative 7 into both side -7/-7 = -5x/-7 + 10/-7

and the answer is y = 5x/7 + 10/-7
