Answer:
Option D is correct that is (-4,-11).
Step-by-step explanation:
We have been given an expression:
We need to find the points of discontinuity
We will first factorize the given expression
Hence, the point of discontinuity is where denominator gives value zero
So, 
Point of discontinuity is -4
hence, after removing the point of discontinuity the function left is:
Hence, put x=-4
Therefore, option D is correct that is (-4,-11).
Equation 1) 2x - 3y = -1
Equation 2) y = x -1
Rearrange equation 2 so that x and y are on the same side. To do so, you subtract x from both sides.
2) -x + y = -1
1) 2x - 3y = -1
Multiply ALL of equation 2 by 2.
2) 2(-x + y = -1)
Simplify.
2) -2x + 2y = -1
1) 2x - 3y = -1
Add equations together.
-y = 0
So, y = 0
Plug in 0 for y in the first equation.
2x - 3y = -1
2x - 3(0) = -1
Simplify.
2x - 0 = -1
2x = -1
Divide both sides by 2.
x = -1/2
(-1/2 , 0)

Answer:
94 pizzas will be sold
Step-by-step explanation:
We have to use the equation and replace 15 with x.
x=15
y=3.4x + 43
y=3.4(15) + 43
y=51 + 43
y=94
(15,94)
There will be 94 pizzas sold nightly if 15 coupons were issued.
