Step-by-step explanation:
She can wear outfits differently in 167 days.
Given that Lucy wants to wear different clothes everyday, and she has 8 dresses, 7 pairs of shoes, and 3 pairs of earrings, and Lucy can choose 1 dress, 1 pair of shoes, and 1 pair of earrings every day, but however 1 dress and 1 pair of shoes don't look good together, to determine, in such circumstances, how many days can she wear outfits differently, the following calculation must be made:
- (8 x 7 x 3) - 1 = X
- 168 - 1 = X
- 167 = X
Therefore, she can wear outfits differently in 167 days.

You have a lot of questions here, I can help with some.
1) To find the inverse, switch the x and f(x) and solve for f(x).
x = 3f(x) - 7
x + 7 = 3(f(x)
(x + 7) / 3 = f(x)
2) It is a function, because each input pairs with only 1 output.
3) Any diagonal line would be a function.
4 - 8 (We can't do without the diagram)
9) f(-9) = 3(-9) - 6
f(-9) = -27 - 6
f(-9) = -33
10) f(-2) = 42 + 3
f(-2) = 45
The equation is a^2 + b^2 = c^2 and the long slanted side is always c so
12 + b^2 = 15
So using the equation a^2 + b^2 = c^2 and the transverse property the answer is 1.732
