It makes sense to let the # of shirts sold be the variable dependent upon the unit cost per shirt.
Notice that the # sold declines as the price increases.
Thus, the slope of this line will be -.
8000 - 5000 3000 shirts
m = ------------------- = ----------------- = -200 shirts per dollar price increase
25 - 40 -15
Answer:
This system has one solution (-1,1)
Step-by-step explanation:
The attached picture shows the solutions for the system
If we equalize the eq. obtain the following
-x=2x+3
From we obtain that x= -1
Using the first equation y=-x, we obtain that y=1
so (-1,1)

Answer:
It states that Angle A = 3x B = 3x + 10 and C = 4x -30
We know that A + B + C = 180
Therefore 3x + 3x + 10 + 4x -30 = 180
10x -20 = 180
10x = 200
Therefore, x = 20
Angle C is 4x -30
= 4 * 20 -30
Angle C = 50
Answer is D
