Answer:
x = 14 and y = 6
Step-by-step explanation:
To find the solution to this problem, we plug in the values of x and y from each answer choice and simplify.
1.
- (11) + (9) = 20. 20 = 20.
- (11) - (9) = 20. 2 ≠ 8.
2.
- (9) + (11) = 20. 20 = 20
- (9) - (11) = 20. -2 ≠ 8.
3.
- (14) + (6) = 20. 20 = 20.
- (14) - (6) = 8. 8 = 8.
4.
- (6) + (14) = 20. 20 = 20
- (6) - (14) = 8. -8 ≠ 8.
Therefore, the correct answer is x = 14 and y = 6.
Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:
( √15 + 8)/7
Step-by-step explanation:
TanA = -√15
.we are to find tan(A-π/4).
In trigonometry
Tan(A-B) = TanA - TanB/1+ tanAtanB
Hence:
tan(A-π/4) = TanA - Tanπ/4/1+ tanAtanπ/4
Substitute tan A value into the formula
tan(A-π/4) = -√15-tanπ/4 / 1+(-√15)(tanπ/4
tan(A-π/4) = -√15-1/1-√15
Rationalize
-√15-1/1-√15 × 1+√15/1+√15
= -√15-√225-1-√15/(1-√225)
= -2√15-15-1/1-15
= -2√15 -16/(-14)
= -2(√15+8)/-14
= √15 + 8/7
Hence the required value is ( √15 + 8)/7
