Solve the following math problem and give me an example please C/-7+3.2=2.7
jasenka [17]
C/-7+3.2=2.7

Step 1) Add 7 to both sides because what you do to one side you must do to the other
         C/<u>-7</u>+3.2=<u>2.7</u>
          <u>  +7          +7
</u>          C/+3.2=9.7

Step 2) Subtract 3.2 from both side
          C/<u>+3.2</u>=<u>9.7
</u>          <u>    -3.2   -3.2
</u>              C/=6.5

Your answer is C=6.5<u>

(5,12)and (2,6) rate of change?<br> Initial value?<br> HURRY i NEED this done.
Otrada [13]

Answer:

Part 1) The rate of change is 2

Part 2) The initial value is 2

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope or rate of change

b is the y-intercept or initial value

step 1

Find the slope or rate of change

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the points

(5,12)and (2,6)

substitute the values in the formula

m=\frac{6-12}{2-5}

m=\frac{-6}{-3}

m=2

therefore

The rate of change is 2

step 2

Find the initial value

we have

m=2

point\ (2,6)

substitute in the equation y=mx+b

6=2(2)+b

solve for b

6=4+b

b=2 ---> initial value

The linear equation is equal to

y=2x+2

The y-intercept or initial value is 2
