For this case we have the following system of equations:
Equating the equations we have:
To find the solutions we factor the equation. To do this, we look for two numbers that, when multiplied, result in -3 and when added, result in -2.
These numbers are: -3 and +1
Thus, the factored equation is:
Then, the solutions for the variable "x" are:
We find the solutions for the variable "y":
Thus, the solutions are:
ANswer:
The domain and range of a function is the set of input and output values, the function can take.
<em />
From the question, we have:
<u>The domain</u>
He cannot mow more than 6 yards a day.
This means that the domain is: 0 to 6
<em>This is properly represented as: [0,6]</em>
<u></u>
<u>The range</u>
When he mows 0 yards, his earnings is:
When he mows 6 yards, his earnings is:
This means that the range is: 0 to 90
<em>This is properly represented as: [0,90]</em>
