Step-by-step explanation:
Answer:
A. Slope is -12 feet per second
B. Yes, it is constant.
<u>Skills needed: Linear Equations, Substitution and Division</u>
Step-by-step explanation:
1) Solving Part A (we need to find the slope):
- The slope is
--> 
, 
, 
, and 
are all values from the table. We know that the left column is the x-values, and the right column is the y-values as that is the conventional way of depicting them.
2) Using the y-values of 1150 and 1090, and their corresponding x-values (5 and 10 respectively), we can get the slope:
- ==> 
==> 
==> 
, so the slope is -12.
==================================================================
1) Part B (analysis)
We can see that no matter what 2 y-values and their corresponding x values we use, the slope always is the same. This means that the rate of change is constant.
You just have to add one eqaution to another :
-x + x -y + 2y = 7 + 7
y = 14
Then apply y = 14 to one of the equations :
eg: x + 2(14) = 7
x + 28 = 7
x = - 21
The awnser is x= -21 y= 14
I hope i awnsered your question
Answer:
The volume of the prism is the area of the base times the height. So to calculate height, divide the volume of a prism by its base area. For this example, the volume of the prism is 500 and its base area is 50. Dividing 500 by 50 results in 10.
1. 1 x-200= -200
2. -200 x 1= -200
3. 2 x -100= -200
4. -100 x 2= -200
5. -20 x 10= -200
6. -10 x 20= -200
7. -40 x 5= -200
8. -5 x 40= -200
Hope this helps! :)
