Calculate the unit price per square foot for each of the flooring types listed above. Which flooring type costs the least per square foot? a. carpet: $375 for 100 square feet

b. laminate: $340 for 80 square feet

c. vinyl: $402 for 120 square feet

Vinyl

Step-by-step explanation:

The cost per square foot are is obtained by :

Total cost / total number of square feet

a. carpet: $375 for 100 square feet

Cost per square foot = $375 / 100

= $3.75 per sq ft

b. laminate: $340 for 80 square feet

Cost per sq ft = $340 / 80

= $4.25

c. vinyl: $402 for 120 square feet

Cost per sq ft = $402 / 120

= $3.35

Arranging from least to highest

Vinyl < carpet < laminate

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
