Select the correct answer.
The table below shows the height of a baseball as it flies through the air.
Height of Baseball
Time in seconds, x 0.1 0.2 0.3
Height in feet, H(x) 5.56 5.7 5.52
0.4
0.5
0.6
5.02
4.2
3.06
Which function best models this set of data?
OA.
Hx) = 1.4x + 5.42
OB.
H(X) = -16x2 + 6.2x + 5.1
OC.
HX) = -16x2 +5.72
OD. H(x) = -16x + 7.16

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

i believe the answer is 323 ft

step-by-step explanation:

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
