3x - 14 = x + 2
- x - x
2x - 14 = 2
+ 14 + 14
2x = 16
2 2
x = 8
4y - 7 = y + 11
- y - y
3y - 7 = 11
+ 7 + 7
3x = 18
3 3
x = 6
(x, y) = (8, 6)
The answer is D.

Answer:
Option 2). -4/3 is the correct answer
Step-by-step explanation:
It is given that,
sin Ø = - 4/5 and cos Ø>0.
sin Ø = opposite side/hypotenuse = - 4/5
Adjacent side = square root (hypotenuse² - opposite side²)
= square root (5² - 4²) = √9 = +3 or -3
cos Ø =Adjacent side/hypotenuse
It is given that, cos Ø>0
cos Ø = 3/5
Therefore tan Ø = Opposite side/Adjacent side = 4/3 or -4/3
The second option is the correct answer -4/3
Option d.
as we know the corner of a square is always 90°. So we can apply that (side of the square)^2+(side of the square)^2 = (diagonal of the side)^2
(side of the square)^2+(side of the square)^2 = 16
16/2=8
8=(side of the square)^2
side of square= squareroot of 8
area of square= squareroot of 8^2=8
hence answer is 8
