Answer:

<h2>B) $10.00</h2>

Step-by-step explanation:

x - Earl's earnings per hour

The equation:

18x = 15(x + 2)         <em>use the distributive property</em>

18x = (15)(x) + (15)(2)

18x = 15x + 30        <em>subtract 15x from both sides</em>

18x - 15x = 15x - 15x + 30

3x = 30        <em>divide both sides by 3</em>

3x : 3 = 30 : 3

x = 10

<span>Multiplicative Inverse.- If two numbers are multiplied together and the product is one. They are the multiplicative inverse of each other, also called reciprocal. </span>

<span>......................................... A.B = 1 , they are the multiplicative inverse of each other. 
</span>

Hi does anyone know the answer?
Artemon [7]

Answer:

The correct equation is actually: y=10x+10.

Jaiden calculated the slope of the line incorrectly, as the y-axis increases by 10, not 2. The correct slope of the line is 20/2, which is equal to 10.

Hope this helps!
