Solve -4x – 8y = -48<br> 8x + 3y = -34.
Likurg_2 [28]

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

Which shows the expressions in the order they would appear on a number line from least to greatest?
ziro4ka [17]
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.

Prove the trigonometric identity!<br><br> Please help!! 50 Points!
Rudiy27

Answer:

:)

Step-by-step explanation:

For simplicity I will substitue x for β.

1-sin(2x)=(cosx-sinx)^2\\1-2sin(x)cos(x)=cos^2x-2sin(x)cos(x)+sin^2x\\1=cos^2(x)+sin^2(x)\\1=1

In the first step I used the identity

sin(2x)=2sin(x)cos(x)

And I factored out (cosx-sinx)^2

Then it's just simple algebra to cancel till the 3rd step where we used another identity derived from the Pythagorean Theorem.

cos^2(x)+sin^2(x)=1

That's it!
