Answer:
x=-5, y=-2
Step-by-step explanation:
3x+2y= -19
-3x-5y= 25
Add the two equations together
3x+2y= -19
-3x-5y= 25
------------------
0x -3y = 6
Divide each side by -3
-3y/-3 = 6/-3
y = -2
Now find x
3x+2y = -19
3x +2(-2) =-19
3x-4 = -19
Add 4 to each side
3x -4+4 = -19+4
3x= -15
divide by 3
3x/3 = -15/3
x = -5
Answer:
x = -5, y = -2
Step-by-step explanation:
3x + 2y = -19
-3x - 5y = 25
Add both equation together.
- 3x + 2y = -19
- <u>+ -3x - 5y = 25</u>
- <u> 0 x -3y = 6</u>
- -3y = 6
Divide each side by -3.
Now, find x.
Substitute the value of y into the equation 3x + 2y = -19
- 3x + 2( -2 ) = -19
- 3x <u>- 4</u> = - 19
Move the constant to the right hand side and change their sign.
Divide both side by 3.
Therefore, x = -5 and y = -2

Answer:
Formula: a² + 2ab + b² = (a + b)²
The square root of 1/9x² = 1/3x so a = 1/3x and b = 1/5y.
The answer is (1/3x + 1/5y)².
In the ratio, the numbers are 2 for the shortest side, 3 for the middle sized side, and 4 for the longest side.
2 is to 6 cm as 4 is to x
2/6 = 4/x
2x = 4 * 6
2x = 24
x = 12
Answer: The longest side measures 12 cm.
