RS has endpoints R(-2,3) and S(-8,-2) whats the midpoints? whats the quadrants?
Answers
R is in Quadrant II and S in Quadrant III.
The midpoint in the x-direction is (-2-8)/2, or -5.
The midpoint in the y-direction is (3-2)/2, or 1/2.
The (single) midpoint is (-5,1/2).

The midpoint of 18.6 and 18.50 is 18.55.
What is a mean?
It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
18.6 and 18.5
The midpoint will be the average value.
Now,
Average = (18.6 + 18.5) / 2
Average = 37.1/2
Average = 18.55
Thus,
The midpoint is 18.55.

For this case, the first thing we must do is define variables.
We have then:
y: number of caps
x: number of shirts
We now write the system of equations that represents the problem:
The graphical solution of the system of equations (see attached image) is:
Therefore, we have 4 shirts and 4 caps.
Answer:
See attached image for the graphic
number of caps = 4
number of shirts = 4
6x + 3y = 36
x + y = 8
If you graph this, it gives you a solution of (4, 4)
This tells us that the friends must buy 4 shirts and 4 caps in order to spend exactly $36 and to have 8 items total.

4x + 5y= 15
-4x + 6y= 7
add the two above equations; the x term cancels out; solve for y
11y= 22
divide both sides by 11
y= 2
STEP 2:
substitute the y value in step 1 into either original equation
4x + 5y= 15
4x + 5(2)= 15
4x + 10= 15
subtract 10 from both sides
4x= 5
divide both sides by 4
x= 5/4
ANSWER: (A) x= 5/4, y= 2 or (5/4, 2)
