Given:
y = mx + b
m = slope
b = y-intercept.
m = 1.35
x = 13
25.43 = 1.35(13) + b
25.43 = 17.55 + b
b = 25.43 - 17.55
b = 7.88
y = 1.35(19) + 7.88
y = 25.65 + 7.88
y = 33.53
The monthly cost for 19HCF is $33.53
C because twice the difference of a number and 5
2 (n-5)
or it can be wrtten as 2(x-5)
2x-2(-2+1)=4
Distribute the -2 to the numbers in parantheses.
2x+4-2=4
Combine all numbers
2x+2=4
Subtract 2 from both sides
2x=2
Then divide by two
x=1
Simplify the left side
4c+9=37
Move all terms NOT containing C to the right side of the equation
4c=28
Divide each term by 4 and simplify
28 divided by 4
Answer
C=7
