Answer:
we get Rate of change = -3
Step-by-step explanation:
We need to calculate the rate of change for the following data:
x y
-1 7
2 -2
7 -17
10 -26
The rate of change can be calculated using slope formula: ![Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=Rate%5C%3Aof%5C%3Achange%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
From the table, we can take any 2 points
Suppose we take (-1,7) and (2,-2)
We have: ![x_1=-1, y_1=7,x_2=2, y_2=-2](https://tex.z-dn.net/?f=x_1%3D-1%2C%20y_1%3D7%2Cx_2%3D2%2C%20y_2%3D-2)
Putting values in formula and finding rate of change
![Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}\\Rate\:of\:change=\frac{-2-7}{2-(-1)}\\Rate\:of\:change=\frac{-9}{2+1}\\Rate\:of\:change=\frac{-9}{3}\\Rate\:of\:change=-3](https://tex.z-dn.net/?f=Rate%5C%3Aof%5C%3Achange%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5CRate%5C%3Aof%5C%3Achange%3D%5Cfrac%7B-2-7%7D%7B2-%28-1%29%7D%5C%5CRate%5C%3Aof%5C%3Achange%3D%5Cfrac%7B-9%7D%7B2%2B1%7D%5C%5CRate%5C%3Aof%5C%3Achange%3D%5Cfrac%7B-9%7D%7B3%7D%5C%5CRate%5C%3Aof%5C%3Achange%3D-3)
So, we get Rate of change = -3
34x+95=3(14x+9)
We move all terms to the left:
34x+95-(3(14x+9))=0
We calculate terms in parentheses: -(3(14x+9)), so:
3(14x+9)
We multiply parentheses
42x+27
Back to the equation:
-(42x+27)
We get rid of parentheses
34x-42x-27+95=0
We add all the numbers together, and all the variables
-8x+68=0
We move all terms containing x to the left, all other terms to the right
-8x=-68
x=-68/-8
x=8+1/2
So 4a=0.24 well its simple
your gonna divide 4 on both sides the 4 crosses out and 0.24 divided by 4 equals 0.06 or just .06 does that make sense?

well all you need to do is try your best
