Answer:
If the lines intersect, the System of equations has One Solution.
The point of intersection between the lines is the solution of the System of equations.
Step-by-step explanation:
By definition, given a System of Linear equations, if the lines intersect its means that that System of equations has One Solution.
Then, the point of intersection 
between the lines is the solution of the System of equations.
Observe the graph attached in the exercise.
You can notice that the are two lines which are intersecting each other at a point.
In this case, you can identify that the intersection between those lines are at the following point:
Where:
(Observe the picture attached)
That is the solution of the System of equations.
Answer:
She earned $20 in tips.
Step-by-step explanation:
First, you need to work out how much pay she'd get for 12 hours work:
12 x $11.25 = $135 for 12 hours work
Then, find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:
2/5 of $11.25 = $4.50
Add both these sums together to get her total pay for hours worked:
$135 + $4.50 = $139.50
Subtract that sum from her total pay to find out how much money she earned in tips:
$159.50 - $139.50 = <u>$20</u>
Answer:
