1) <span>B)3x+6y=22
6x+12y=44
because the equations are equivalent to each other
2*(3x+6y=22) -----> 6x+12y=44
2) </span><span>5x+10y=15 should be multiplied by -2, to get 5x*(-2)=-10x, and x then can be eliminated

The rate of change represents the <em>variable production</em> cost rate. The <em>production</em> cost is increased in 1200 units per each <em>additional</em> manufactured car.
<h3>
Interpretation of a linear function</h3>
Let be and the production cost and the number of vehicles produced, it there is a <em>linear</em> relationship between the two variables, then we have the following formula:
(1)
Where:
- - Fixed production costs.
- - Variable production cost rate.
In a nutshell, the rate of change represents the <em>variable production</em> cost rate. The <em>production</em> cost is increased in 1200 units per each <em>additional</em> manufactured car.
