Answer:
m = -32.10
Step-by-step explanation:
You solve this the same way you do any two-step linear equation.
1. Subtract the constant that is on the side of the equal sign with the variable term:
m/5 = -6.42
2. Multiply by the inverse of the coefficient of the variable. That means multiply by 5 in this case.
m = 5·(-6.42) = -32.10
_____
Of course, the rules of equality tell you whatever you do to one side of the equation must also be done to the other side. So, when we say subtract 0.12, we mean subtract 0.12 from both sides of the equation. The same for multiplication or division.
Answer:
Sigh no body wants to answer this one, so I'll just take my points back
Answer:
A
Step-by-step explanation:
y = mx + c
y = -½x + 1
D
Number of hours is x values and cost of service is y.
To find slope you have to find the change in y over the change in x.
We can use any points in the table to calculate this amount.
Eg, 3-5 hours and 125-175 dollars.
The difference in y values is $50 and the difference in hours is 2.
50/2=25
The slope is 25
