Answer:
y=2x-5
Step-by-step explanation:
y=mx+c
mx=slope
In this case, the slope is already given to you which means the m=2.
y=2x+c.
The coordinates are (14, 23) and when you put -5 into c, the line goes through the coordinates (14, 23).
Hope this helps!
Answer:
<em>Perimeter of ΔMNK is </em><em>6 in.</em>
Step-by-step explanation:
<u>Midpoint Theorem-</u>
It states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.
M, N and K are the midpoints of the sides.
So,
Perimeter of a ΔABC is 12 in, i.e 
in
Perimeter of ΔMNK is,
in
Answer:
They need to sell 3 tees, and incurred $60.
Step-by-step explanation:
What is the revenue equation? R = 20x, where x is the # of tees sold.
What is the cost equation? C = 5x + 45, where x is the # of tees sold.
Set those two equations equal, we get:
20x = 5x + 45, 15x = 45, x = 3.
3*5 + 45 = 60.
