Step-by-step explanation:
The domain of this relation (not a function) is x = -5. The relation is not defined for any other x value.
Answer:
Negative
Step-by-step explanation:
If a line has a positive slope, then y always increases when x increases and y always decreases when x decreases. Thus, the graph of the line starts at the bottom left and goes towards the top right.
Answer:
Caterer One: C = 55n
Caterer Two: C = 40n + 550
Caterer Three: C = 35n + 800
Step-by-step explanation:
It's called "solve the equation for 'y' ". That means move things
around so that you end up with 'y' all alone on one side, and
everything else on the other side.
You started with 9x - 7y = -7
Subtract 9x from each side: - 7y = -9x - 7
Divide each side by -7 : y = 9/7 x + 1
