Independent variable - represents a quantity that is being manipulated
dependent variable- represents a quantity whose value depends on how the independent variable is manipulated.
The y intercept is 6. When looking for features like this make sure the y variable is isolated so you can identify them, so in this case you isolate it by subtracting 3x from both sides to get y=-3x+6. The y intercept would be the constant 6.
2(b + 6) - 7 <= -3b - 30
Let's distribute the 2.
2b + 12 - 7 <= -3b - 30
Combine like terms.
2b + 5 <= -3b - 30
Subtract 2b from both sides and add 30 to both sides.
35 <= -5b
Divide both sides by -5.
-7 >= b
We had to flip the sign because we divided by a negative number.
This means that b <= -7. D is correct.
The relationship between the total cost and the amount of sugar is an illustration of a linear equation.
- The equation that relates C to S is:
. - See attachment for the graph of
![\mathbf{S = 3500 + 125C}](https://tex.z-dn.net/?f=%5Cmathbf%7BS%20%3D%203500%20%2B%20125C%7D)
The given parameters are:
<em />
<em> --- the cost of renting the truck</em>
<em />
<em> -- the cost of each ton transported</em>
<em />
So, the equation is:
![\mathbf{S = Base + Rate \times C}](https://tex.z-dn.net/?f=%5Cmathbf%7BS%20%3D%20Base%20%2B%20Rate%20%5Ctimes%20C%7D)
Substitute known values
![\mathbf{S = 3500 + 125 \times C}](https://tex.z-dn.net/?f=%5Cmathbf%7BS%20%3D%203500%20%2B%20125%20%5Ctimes%20C%7D)
![\mathbf{S = 3500 + 125C}](https://tex.z-dn.net/?f=%5Cmathbf%7BS%20%3D%203500%20%2B%20125C%7D)
Hence, the equation that relates C to S is: ![\mathbf{S = 3500 + 125C}](https://tex.z-dn.net/?f=%5Cmathbf%7BS%20%3D%203500%20%2B%20125C%7D)
