Answer:

B. The two lines are neither parallel nor perpendicular.

Step-by-step explanation:

First, put both lines into the same format. In this example, we're going to use y=mx+b format.

x - 4y = -9

-4y = -x + -9

y = (-x + -9) / -4

y = (x+9)/-4

y = (-1/4)x + (-9/4)

y = 3x - 7

If two lines are parallel, they have the same slope. (ie 4 and 4)

If two lines are perpendicular, one line's slope is the negative reciprocal of the other. (ie 4 and -1/4)

Neither is true here.

Eli and Karl each throw a basketball straight up in the air at the same time. Eli is standing on a deck and the height of his ba

tino4ka555 [31]

We are to find the time at which the height of basketball thrown by Eli and Karl is equal. We have the functions which model the heights of both basketballs. So by equating the functions representing the height of both basketballs we can find the value of x from that equation at which the height is same for both basketballs.

$-4.9 x^{2} +12x+2.5=-4.9 x^{2} +14x \\ \\ 
12x+2.5=14x \\ \\ 
2.5=2x \\ \\ 
x=1.25$

Thus after 1.25 seconds the height of basketballs thrown by Eli and Karl will be at the same height. This can be verified by finding the heights of both at x=1.25

For Eli:
$Height=f(1.25)=-4.9 (1.25)^{2}+12(1.25)+2.5=9.84375$

For Karl:
$Height=f(1.25)=-4.9 (1.25)^{2}+14(1.25)=9.84375$

Thus height of both basketball is equal after 1.25 seconds
