Answer:
C. C-B,
A. A-B,
D. B-S
Step-by-step explanation:
Given,
Total types of pie = 6 ( Cherry, Apple, Blueberry, Strawberry, Pumpkin, and Key Lime ),
For these pie we need to make any two types of pie,
Here, the order matters ( for example C-A and A-C are same )
So, the total possible ways of getting any two pies =
= 15 ( C-A, C-B, C-S, C-P, C-K, A-B, A-S, A-P, A-K, B-S, B-P, B-K, S-P, S-K, P-K)
Hence, OPTIONS C, A and B are correct.

Answer:
C
Step-by-step explanation:
ley y = f(x) and rearrange making x the subject
y = - 1 ( add 1 to both sides )
y + 1 = ( multiply both sides by (x + 5)
(y + 1)(x + 5) = 1 ← expand factors using FOIL
xy + 5y + x + 5 = 1 , that is
xy + x + 5y + 5 = 1 ( factor first/second and third/fourth terms on left side )
x(y + 1) + 5(y + 1) = 1 ← factor out (y + 1) from each term on left side
(y + 1)(x + 5) = 1 ( divide both sides by (y + 1) )
x + 5 = ( subtract 5 from both sides )
x = - 5
Change y back into terms of x with x = (x) , then
(x) =
- 5 where x ≠ - 1
