<h2>The height of the rocket increases for some time and then decreases for some time.</h2>
The height from the ground increases from 4 to 26, then decreases from 26 to 0.
Why the others are wrong.
A. The height of the rocket changes at a constant rate for the entire time.
The graph is a curve. This means the rate is not constant. If it were constant, the graph would be linear - a straight line.
C. The height of the rocket remains constant for some time.
The graph is a curve. This means the rate is not constant. If it were constant, the graph would be linear - a straight line.
D. The height of the rocket decreases for some time and then increases for some time.
This implies the graph decreases first then increases. However, the rocket will increase, then decrease.

Answer:
x=2, y= 21
Step-by-step explanation:
y = 6x + 9
y = 7x + 7
Since both equations are equal to y, we can set them equal to each other
6x+9 = 7x+7
Subtract 6x from each side
6x+9-6x = 7x -6x+7
9 = x+7
Subtract 7 from each side
9-7 = x+7-7
x=2
Now we need to find y
y = 6x+9
y = 6(2) +9
y = 12 +9
y = 21
Answer:
Option C.
Step-by-step explanation:
As we can see from the graph, we have plotted the different points.
If the line drawn through the scatter plots, shows the relationship between the length x and mass f(x) then the function will be in the form of
f(x) = mx + b
where m = slope of the line that fits the best
b = y-intercept of the line
Since the plotted line passes through two pints (1, 1) and (10, 94).
Then the slope m = 
m = 
m = 
m = 10.3
Now we place the coordinates (1, 1) in the equation to find the value of y-intercept b.
1 = 10.3 + b
b = 1 - 10.3
b = -9.3 ≈ 9
So the function will be f(x) = 10.3x - 9
Option C is the answer.
