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: 102 children and 41 adults swam at the pool that day.
Step-by-step explanation:
Let x represent the number of children that swam at the public pool that day.
Let y represent the number of adult that swam at the public pool that day.
On that certain hot summer's day, 143 people used the public swimming pool. It means that
x + y = 143
The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $219.75. It means that
1.25x + 2.25y = 219.75- - - - - - - - -1
Substituting x = 143 - y into equation 1, it becomes
1.25(143 - y) + 2.25y = 219.75
178.75 - 1.25y + 2.25y = 219.75
- 1.25y + 2.25y = 219.75 - 178.75
y = 41
x = 143 - y = 143 - 41
x = 102
Answer:
The golf ball is 2 times a likely to be orange as it is to be pink
Step-by-step explanation:
A. green = 18, pink+white+orange = 23
18 not > 23
B. pink 
white orange green
C. pink x 2 = orange?
4 x 2 = 8
D. white x 7 = green?
white = 11
green = 18
11 x 7 = 77 18
b×h=a
this is how to represent it and it is a direct variation.
