Answer: 4x + 100

Step-by-step explanation:

The company charges $4 per foot plus an installation charge of $100.

There is therefore both a fixed element and a variable element.

The fixed element is the $100 installation charge

The variable element is 4 * the number of square feet of carpet which is x: 4 * x

Formula puts them together to give:

= Variable cost + Fixed cost

= 4 * x + 100

= 4x + 100

Find the equation of the line that passes through the following lines points (0,-1) and (3,12).​
Temka [501]

Answer:

y=13/3x-1

Step-by-step explanation:

k=(y2-y1) /(x2-x1)

A(0,-1) x1=0,y1=-1

B(3,12) x2=3, y2=12

k=(12-(-1))/(3-0)

k=(12+1)/3

k=13/3

y-y1=k(x-x1)

y-(-1)=13/3(x-0)

y+1=13/3*x

y=13/3*x-1

What is the equation of the line? (Answer choices & graph attached.)
soldi70 [24.7K]

Answer:

The answer to your question is: first option

Step-by-step explanation:

Data

A (2, 5)

B (-2, -3)

Formula

Slope = m (y2 - y1)/(x2 - x1)

Line   (y - y1) = m(x - x1)}

Process

            m = (- 3 - 5) / (-2 - 2)

            m = -8 / -4

           m = 2

Substitution in line equation

         (y + 3) = 2 (x + 2)   Line equation

Now Tn=a+(n-1)d

Tn=27+(n-1)(-2)

Tn=27-2n+2
