A carpet installer charges a flat rate of $40, plus $1.50 per square foot for labor. So, the total cost for labor depends on the
2 answers:
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 , 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.

Answer:
D
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle will always total 180.
Therefore:
Let’s solve for <em>x: </em>
Combine LIke Terms:
Add:
Subtract 80 from both sides:
Divide both sides by 25:
Therefore, the value of <em>x </em>is 4.
Now, to find A, we can substitute it for A.
A is measured by:
Substitute 4 for <em>x</em> and evaluate:
Hence, our answer is D.
