Answer:

y = x + 4

Step-by-step explanation:

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Slope-Intercept Form: y = mx + b

Step 1: Define variables and points

<em>b</em> = 4

Random point (3, 7)

Step 2: Find slope

m = (7 - 4)/(3 - 0)

m = 3/3

m = 1

y = x + <em>b</em>

<em />

Step 3: Rewrite linear equation

y = x + 4

a gas company in massachusetts charges $1.30 for 16.7 ft3 of natural gas. convert this rate to dollars per liter of gas
Katyanochek1 [597]

By using a change of units, we can see that the rate in dollars per liter is:

R = $0.0027 per liter.

<h3>How to convert the rate?</h3>

Here we have a rate in dollars per cubic foot, and we want to rewrite this in dollars per liter. So we just need to apply a change of units.

The original rate is in dollars per square foot, and it is given by:

R = $1.30 for 16.7ft^3

We know that the relation between cubic feet and liters is:

1ft^3 = 28.32 L

Then, if we apply a change of units, we can rewrite the volume as:

16.7ft^3 = 16.7*(28.32) L = 472.9 L

Then the rate is $1.30 per 472.9 L, taking the quotient we get:

R = ($1.30/472.9 L) = $0.0027 per liter.

Which is greater 1/3 or 30%
Brilliant_brown [7]
30% = 30/100 = (30 x 3)/(100 x 3) = 90/300

1/3 = (1 x 100)/(3 x 100) = 100/300

As    90/300 < 100/300

Therefore 30% < 1/3
