How do you graph 4x+5y=-15

Isolate y on the left side:
- Move 4x to the right side
- Then divide the entire equation by 5

This gives you:

y = - $\frac{4}{5}$ x - 3

This gives you the equation in the familiar (y = ax + b) format. Graph this by finding your intercepts.
- Crosses the y-axis when you put 0 in for x --> y = -3
- Crosses the x-axis when you put 0 in for y --> x = - $\frac{15}{4}$

Then just draw your straight line through both points.

If a trench is 102’-6” long by 5’-4” wide and 3’-3” deep, what is the volume of the soil that was removed per cubic feet?

zzz [600]

Considering that the trench is modeled by a rectangular prism, the volume that was removed is 1776 cubic feet.

The volume of a <u>rectangular prism of length l, width w and height h</u> is given by:

$V = lwh$

In this problem, we want the measures in feet, and considering that 1 feet is 12 inches:

The length is of 102' 6''(102 feet and 6 inches), hence $l = 102.5$ .

The width is of 5' 4'', hence $w = 5.33$ .

The depth(height) is of 3' 3'', hence $h = 3.25$ .

Then:

$V = lwh = 102.5(5.33)(3.25) = 1776$

The volume that was removed is 1776 cubic feet.

ace bike rentals rents bikes for $28 per day. Renters can keep the bike for 8 hours. Bart's bikes rents bikes for $30 per day. R

lyudmila [28]

Bart company charges a lower rate. It is lower by rate $ 0.5 per hour

<h3><u>Solution:</u></h3>

Given that Ace bike rentals rents bikes for $28 per day. Renters can keep the bike for 8 hours

Also given that Bart's bikes rents bikes for $30 per day. Renters can keep the bike for 10 hours

To find: company that charges lower rate

Let us find the hourly rate of Ace and Bart

$\text {hourly rate }=\frac{\text { Rental price }}{\text { total time in a day }}$

<em><u>Hourly rate of Ace company:</u></em>

Rental price = $28

total time in a day 8 hours

$\text {hourly rate }=\frac{28}{8}=3.5$

So the hourly rate of Ace company is $ 3.5 per hour

<em><u>Hourly rate of Bart company:</u></em>

Rental price = $ 30

total time in a day 10 hours

$\text {hourly rate }=\frac{30}{10}=3$

So the hourly rate of Bart company is $ 3 per hour

<em><u>Comparing hourly rate of both companies</u></em>

Ace company is $ 3.5 per hour

Bart company is $ 3 per hour

Bart company < Ace company

3 < 3.5

Thus bart company charges a lower rate

<h3><em><u>How much lower?</u></em></h3>

hourly rate of Ace company - hourly rate of Bart company = 3.5 - 3 = 0.5

So, it is lower by rate $0.5 per hour
