Answer:

A. 16 m

B. At t = 2 and t = 6

C. 8 seconds

Step-by-step explanation:

Maximum height is at the vertex

(4,16). So maximum height is 16 m at t = 4

The rocket is at a height of 12m at two distinct times:

At 2 seconds and again at 6 seconds

The rocket is in air when the height is not zero, I.e between t=0 and t=8

8-0 = 8 seconds

Answer:

x = 8/13

Step-by-step explanation:

6 - 3x - 3/5(15x + 20) = 7(2x/7 - 2) - x

6 - 3x - 9x - 12 = 2x - 14 - x

6 - 12 + 14 = 2x - x + 3x + 9x

8 = 13x

x = 8/13

What is the solution to the following system of linear equations?

Lostsunrise [7]

x − 2y = −1 => x = 2y -1

2x + y = −12
2(2y - 1) + y = -12
4y - 2 + y = -12
5y = -10
y = -2
x = 2·(-2) - 1
x = -4 - 1
x = -5
