In the function y = 1.25x + 5, y represents the cost of a foot of cable and x represents the number of feet. how much does the cost of cable increase for every foot?
a) x
b) $1.25
c) $5.00
d) $6.25

i will medal

The correct answer is B). $1.25  

Step-by-step explanation:

The function is given to be :

y = 1.25x + 5

where y represents the cost of a foot of cable and x represents the number of feet

Here , 5 represents the initial cost of the cable

And 1.25 represents the cost of the cable which increases for every foot

Thus, The amount of cost of cable which increases for every foot = $1.25

Therefore, The correct answer is B). $1.25

step-by-step explanation:

8^1/3=2

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
