Answer:
x= -1/2 and -32
y = -10
Step-by-step explanation:
1) 2(-4x-8y)= (-48)2
8x+3y =-34
*to create a way to cancel out the x*
2) -8x-16y= -96
8x+3y= -34
*add them
-8x +8x =0
-16y + 3y = -13y
-96+ -34= -130
3) -13y =-130
isolate y
4) y = -10
*plug in* to find x into both original equations*
5) 8x + 3(-10) = -34. -4x-8(-10)= -48
*follow order of operations to solve for x
6) 8x -30 =-34. -4x +80 = -48
7) 8x =-4. -4x =128
8) x= -1/2. x = -32
17 over 9, Square root of 6, Square root of 15, Square root of 30, 33.
If you make 17 over 9 into a mixed number, you get 1 and 8/9. the square root of 6 is between 2(square root of 4) and 3(square root of 9). The square root of 15 is between 3 and 4(square root of 16). The square root of 30 is between 5(square root of 25) and 6(square root of 36)... then 33 is an outlier.
Answer:
:)
Step-by-step explanation:
For simplicity I will substitue 
for β.
In the first step I used the identity
And I factored out 
Then it's just simple algebra to cancel till the 3rd step where we used another identity derived from the Pythagorean Theorem.
That's it!
