Answer:
1
Step-by-step explanation:
1+1=2
1-1=0
you can do this the hard way by doing a system of equations
or the easy way by guessing and checking
The equation shows that the pastries that must be sold at $3.55 each in order to make a profit is 23.
<h3>How to calculate the expression?</h3>
Let the number of units be represented by x.
Based on the information given, the equation will be:
75 + (0.15 × x) = 3.55 × x
75 + 0.15x = 3.55x
3.55x - 0.15x = 75
3.40x = 75
x = 75/3.40
x = 23
Therefore, the number is 23.

Answer:
The solution would be C. (2, -4)
Step-by-step explanation: Equation: 2y = -3x - 2
1. (2, -3)
2(-3) = -3(2) - 2
-6 = -6 - 2
-6 = -8 (Not a solution)
2. (-3, 2)
2(2) = -3(-3) - 2
4 = 9 - 2
4 = 7 (Not a solution)
3. (2, -4)
2(-4) = -3(2) - 2
-8 = -6 - 2
-8 = -8 (Solution)
4. (-4, 2)
2(2) = -4(-4) - 2
4 = 12 - 2
4 = 10 (Not a solution)
