Answer:  Proportional

Step-by-step explanation:

Given : A flat rate charged by the carpet installer = $40

On addition to that , he charges $1.50 per square foot for labor.

Then , Total cost of carpet= Fixed rate of $40 +  $1.50 per square foot for labor.

Let x be the area of the carpet in square feet.

Then, the total cost ( in $)= 40 +1.50x , which is a linear function with slope 1.50.

According to the definition of linear function , we have

A linear function is in the form  of y=mx+c , it shows that the relationship between x and y is proportional.

That means ,  The relationship between the total cost for labor and the amount of carpet installed is proportional.

A number decreased by the total of the number and fourteen
Charra [1.4K]

The answer to this would be x-(x+14)

Here's an explanation:

Let x represent the unknown number. The problem says that x has been decreased by the sum of x and 14. So, to put this in a form of an equation, it would be x-(x+14), since you have to do the addition first before you can subtract the two number since you don't know what x is. This equation is equal to -14 no matter what x is.

Jessica is a custodian at Oracle Arena. She waxes 20 m² of the floor in = of an hour. Jessica
Wewaii [24]

The complete question is as follows:

Jessica is a custodian at Oracle Arena. She waxes 20 \mathbf{m^{2}} of the floor in \mathbf{\frac{3}{5}} of and hour. At this rate, how many square meters can she wax per hour ?

Answer:

\mathbf{\frac{100}{3}\approx33.33 \ m^{2} \ per \ hour}

Step-by-step explanation:

\textrm{rate}=\frac{\textrm{Area waxed in square meter}}{\textrm{Time taken to wax in hours}}

\textrm{rate}=\frac{20 \ \textrm{m}^{2}}{\frac{3}{5} \ \textrm{hours}}

\textrm{rate}=\frac{20\times5}{3}

\mathbf{rate=\frac{100}{3}\approx33.33 \ m^{2} \ per \ hour}
