Answer:
the solution is (-8, 4)
Step-by-step explanation:
Let's use the addition/subtraction method here to eliminate one variable:
-x+y=4
x+3y=4
Combining these two equations results in
4y = 8, so that y = 2. Substituting y = 2 into the second equation, we get:
x + 3(2) = 4, or x = -2.
Then the solution is (-8, 4)
Answer:
27/4 or negative 3/4
Step-by-step explanation:
If it was 23 degrees below zero it would be -23 degrees
Y=40x + 225
Because x is your per hour cost.
