Answer:
2/5
Step-by-step explanation:
Let's simplify this equation to find the slope. I am going to make this into
y = mx+b form where m is the slope and b is the y-intercept.
y - 3 = 2/5(x+7)
y - 3 = 2/5(x) + 14/5
y = 2/5(x) + (14/5 + 3)
y = 2/5(x) + 29/15
The slope of this equation is 2/5

There are 12 months in a year so you times 525 by 12
It seems that you have missed the most important detail for us to answer this question which is the table where we can base the values. I would be very much interested to help of you are going to attach it here. Let me know if you need more help next time. Have a great day!

Answer:
- C. (-∞, -2)∪(-2, 1)∪(1, ∞)
- A. The first 12 are $2 ea; $1 ea after
Step-by-step explanation:
1. The denominator in the first part of the function definition factors as ...
x² +x -2 = (x -1)(x +2)
This has zeros at x = -2 and x = 1, which will be values of x excluded from the domain. (These zeros are in the domain x < 2, which is applicable to this part of the function definition.)
The second part of the function definition is defined for all x ≥ 2, so the only exclusions are x = -2 and x = 1. The domain of the piecewise function is ...
(-∞, -2)∪(-2, 1)∪(1, ∞)

2. It is helpful to take a look at the graph to see what the axis labels are. The x-axis is labeled "number of cupcakes", so "12" on that axis means "12 cupcakes". The y-axis is labeled "total cost", which we are to presume is in dollars. That means the slope of the graph is Δy/Δx = "dollars per cupcake", the cost of one cupcake.
We observe that the slope of the graph decreases at x=12. This means the cost of a cupcake goes down after 12 are purchased. The appropriate description is ...
The first 12 cupcakes cost $2 each, and all cupcakes after that cost $1 each.
(The other choices have either increasing slope at the breakpoint, or a different breakpoint, or both, so cannot be right.)
