The cost of renting roller blades is $4 plus $3.50 for each hour that the roller blades are rented. Write an expression to repre
Pavel [41]

Answer:

The expression is equal to 3.50h+4

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

y=mx+b

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

m=\$3.50\ per\ hour

The y-intercept is equal to

b=\$4 ----> value of y when the value of x is equal to zero

substitute

y=3.50x+4

For x=h hours

substitute

y=3.50h+4

Write the equation of the lines resented below in slope-intercept form
scoray [572]

Slope intercept form: y = mx + b

mx = slope

b = y-intercept

We know the y intercept is 0, so nothing will be written there.

To find the slope of this line, we can use the slope formula.

\frac{y.2 - y.1}{x.2 - x.1} = m

We'll use the points (1, 0) and (3, 1) to find the slope.

Now we can just plug these values into the equation to find the slope.

1 - 0 / 3 - 1

1 / 2

The slope of the line is 1/2, or 0.5.

The slope-intercept form of this line can be written as:

y = 0.5x

Hunter placed 2 red, 3 blue, 1 yellow, 8 black, and 7 white straws into a bag.
Sphinxa [80]
7/21 or 1/3rd, it's just a ratio of white to all, there's 7 white straws and 21 in all, then you can simplify it down to 1/3rd.
