7q + 2p = 29 & 2p - q =5

faltersainse [42]

Eliminate p terms
times 2nd equation by -1
q-2p=-5
add to 2nd equation

q-2p=-5
<u>7q+2p=29 +</u>
8q+0p=24

8q=24
divide both sides by 8
q=3
sub back

2p-q=5
2p-3=5
add 3
2p=8
divide by 2
p=4

p=4
q=3

A football is kicked from the ground and follows the graph of the function y = –t2 + 3t, where y represents height and t represe

vesna_86 [32]

Answer:

The height of the objects are the same after 2 seconds.

Step-by-step explanation:

In order to calculate at which time both objects have the same height we need to find the value of t that makes both equations equal. Therefore:

$-t^2 + 3t = -t + 4\\t^2 - 3t - t + 4 = 0\\t^2 - 4t + 4 = 0\\t_{1,2} = \frac{-(-4) \pm \sqrt{(-4)^2 - 4*1*4}}{2*1} = \frac{4 \pm \sqrt{16 - 16}}{2}\\t_{1,2} = \frac{4}{2} = 2$
