(will give quick brainliest & many many points! )

the linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time, x, measured in seconds: {graph pictured}

use complete sentences

part a: during what interval(s) of the domain is the water balloon's height increasing?

part b: during what interval(s) of the domain is the water balloon's height staying the same?

part c: during what interval(s) of the domain is the water balloon's height decreasing the fastest? use complete sentences to support your answer.

part d: use the constraints of the real-world situation to predict the height of the water balloon at 14 seconds. use complete sentences to support your answer.

answer:

see below

step-by-step explanation:

part a: from the graph you can see that the graph is increasing between 0 and 2.  

part b: the height is staying the same where the graph is a horizontal line. (slope of zero) between 2 and 4.  

part c: the balloons height is decreasing the fastest from 8 to 10.   this is where the graph has the steepest negative slope.  

part d:   from the graph- at 14 seconds the balloon remains on the ground as it hit the ground at 10 seconds.   height would = 0

6x - 42 + x = 15 +9x + 5 ;
7x - 42 = 20 + 9x;
7x - 9x = 20 + 42;
-2x = 62;
x = -31;
