Answer:
x = -3 and y = -4
x + y = -3-4 = -7
Step-by-step explanation:
-4x + 9y = -11 ------------------------------------------------------------------------(1)
-3x + 7y = -9--------------------------------------------------------------------------(2)
multiply through equation (1) by 3 and multiply through equation(2) by 4
-12x + 27y = -33 -----------------------------------------------------------------------(3)
-12x + 28y = -36 ----------------------------------------------------------------------(4)
subtract equation (1) from equation (2)
y = -3
substitute y = -3 into equation (2)
-3x + 7(-3) = -9
-3x -21 = -9
add 21 to both-side of the equation
-3x -21 + 21 = -9 + 21
-3x = 12
divide both-side of the equation by -3
-3x/-3 = 12/-3
x = -4
x = -3 and y = -4
Subtract 4 from both sides.
Subtract 4 from 36 to get 32.
Divide both sides by −8. Since −8 is <0, the inequality direction is changed.
Divide 32 by −8 to get −4.

Answer:
? = 13.6
Step-by-step explanation:
Let unknown angle be x
so
tan x = p/b
tan x = 8/33
x =tan‐¹(8/33)
or, x = 13.62699486
so, x = 13.6
Answer:
Unlikely
Step-by-step explanation:
The probability of picking a number divisible by 5 is 2/12 or 1/6. So its pretty unlikely.
