Step-by-step explanation:
Y= x - 2. Y = 3x + 5
Putting value of y
x - 2 = 3x + 5
-2 - 5 = 3x - x
-7 = 2x
-7/2 = x
Putting value of x
Y = 3(-7/2) + 5
Y = - 10.5 + 5
Y = - 5.5

Answer:
The demand will drop approximately 23 T-shirt per month.
Step-by-step explanation:
Consider the provided formula.

You currently sell T-shirts for $15 each and you raise your price by $2 per month,
That means p=$15 and 
We need to find how fast demand will drop.
So differentiate the above function with respect to time.


Substitute the respective values as shown:


Hence, the demand will drop approximately 23 T-shirt per month.
2x + 7y + 2 = 0
2(-1) + 7(-3) + 2 = 0
-2 - 21 + 2 = 0
-21 = 0
125m-75m+43,875=45,450-175m
We simplify the equation to the form, which is simple to understand
125m-75m+43,875=45,450-175m
We move all terms containing m to the left and all other terms to the right.
+125m-75m+175m=+45.45-43.875
We simplify left and right side of the equation.
+225m=+1.575
We divide both sides of the equation by 225 to get m.
m=0.007
