No; a domain value has two range values.

x = -2 then y = 1 and 2

they would form a vertical line, which tells us that it's not a function

The cost to manufacture t shirts can be represented by the function c(x)=10.5x complete the following statement about the functi

Advocard [28]

For this case we have:

Cost of manufactures of T-shirts $C(x)=10.5x$

where x represents the number of T-shirts

Part A:

Substituting $x = 8$ in the total cost equation you have to:

$C (8) = (10.5) (8)\\\\C (8) = 84\\$

Thus, the cost of 8 shirts will be $C (8) = 84\\$

Part B:

If $x = 12$ then

$C (12) = (10.5) (12)\\\\C (12) = 126\\$

Thus, the cost of 12 shirts will be $C (12) = 126\\$

Answer:

$C (8) = 84\\\\C (12) = 126\\\\$

frozen [14]

Answer:

$2\frac{2}{3}\text{ ft}^3\approx 2.67\text{ ft}^3$

Step-by-step explanation:

We have been given that Martha has 8 cubic feet of putting soil in the 3 flowerpots. She wants to put the same amount of soil in each pot.

To find the amount of soil in each pot, we need to divide total soil (8 cubic feet) by number of pots (3) as shown below:

$\text{Amount of soil in each pot}=\frac{8\text{ ft}^3}{3}$

$\text{Amount of soil in each pot}=2\frac{2}{3}\text{ ft}^3$

$\text{Amount of soil in each pot}=2.6666\text{ ft}^3$

$\text{Amount of soil in each pot}\approx 2.67\text{ ft}^3$

Therefore, Martha needs to put approximately 2.67 cubic feet of soil in each flower pot.
