Answer:
The expression is equal to 
Step-by-step explanation:
Let
x ----> the number of hours that the roller blades are rented
y ----> the cost of renting roller blades in dollars
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem we have
The slope is equal to

The y-intercept is equal to
----> value of y when the value of x is equal to zero
substitute

For x=h hours
substitute

Answer:
Step-by-step explanation:
-5x + 35 = 40
Subract 35 from both sides -5x + 35 - 35 = 40 - 35 = (-5x = 5)
Divide -5 from both sides -5x / -5 = 5 / -5 =
x = -1
Answer:
-23
Step-by-step explanation:
you calculate 49-|6-14|x 9
you then calculate the absolute value
49-|-8|x 9
then multiply the numbers
49-8 x 9
calculate those numbers
49 - 72
your solution will be -23
First do 104/4 which equals which equals 26
so you can drive 26miles on one gallon
then do 78/26 which equals 3
so you used 3 gallons of gas on trip 2
