Answer:
is the system of equations representing the situation.
Step-by-step explanation:
Given:
Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes.
Now, to find the system of equations representing the situation.
<u><em>Let the number of haircuts be </em></u><u><em /></u>
<u><em>Let the number of hair dyes be </em></u><u><em /></u>
So, Alexandra can give 3 haircuts and 2 hair dyes in:
Now, giving 2 haircuts and 4 hair dyes in:
Therefore,
is the system of equations representing the situation.
According to the given graph, the function is not increasing from x = -1 to x = 1.
Remember that not increasing behavior is expressed as a horizontal line.
<h2>Hence, the interval is [-1, 1].</h2>
