If you add 5x to 2x+2 you will get 7x+2. You would set this equation equal to 80, so it would be 7x+2=80. When you solve this you will get 11.1428571429, which can be rounded to 11, 11.1, or 11.14, whichever you prefer. 
        
             
        
        
        
Answer:
The slope is 13.
The x intercept is  .
.
The y intercept is  .
.
Step-by-step explanation:
1. Finding the slope.
This is a linear equation, because <u>it's graph forms a line</u>. In a linear equation, the slope is always the value that multiplies x. In this case, x is being multiplied by 13, therefore, <u>the slope is 13</u>.
2. Finding the x intercept.
The x intercept is found when the value of y is 0. Let's replace the value of y for 0 in the equation and solve the x:

<u>The x intercept is </u> <u>.</u>
<u>.</u>
3. Finding the y intercept.
The y intercept is found when the value of x is 0. Let's replace the value of x for 0 in the equation and solve the y:

<u>The y intercept is </u> <u>.</u>
<u>.</u>

Answer:
5,376in^3
Step-by-step explanation:
find the volume of the smaller box first 
10×4×12 = 480in^3 
find volume of bigger box 
17×12×24 = 4,896in^3 
add both volumes 4,896 +480 = 5,376in^3
