Answer:

X=6. Y= - 6

Step-by-step explanation:

Put y=6-2x in b)

4x+3(6-2x)=6

4x+18-6x=6

-2x=6-18

- 2x=-12

Divide both sides by - 2

X=6

Put x=6 in y = 6-2x

Y=6-2(6)

Y=-6

Answer:

13 seconds.

Step-by-step explanation:

Given

$h = -4.9(t - 13)(t + 2).$

Required

Determine a reasonable solution for t

To do this, we equate h to 0.

$h = -4.9(t - 13)(t + 2).$ becomes

$0 = -4.9(t - 13)(t + 2).$

Divide through by -4.9

$0 = (t - 13)(t + 2).$

Reorder the expression

$(t - 13)(t + 2) = 0.$

Split

$t-13 = 0$ or $t + 2 = 0$

This gives:

$t = 13$ or $t = -2$

But time can't be negative, So:

$t = 13$
