X - y = 4
-y = 4 + x
y = -4 -x
x + y = 4
So, it's B
Answer:
I think you mean this :
![\sqrt{x - 5} = 6 \\ = > {( \sqrt{x - 5} })^{2} = {6}^{2} \\ = > x - 5 = 36 \\ = > x = 36 + 5 \\ = > x = 41](https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%20-%205%7D%20%3D%206%20%5C%5C%20%20%3D%20%20%3E%20%20%7B%28%20%5Csqrt%7Bx%20-%205%7D%20%7D%29%5E%7B2%7D%20%20%3D%20%20%7B6%7D%5E%7B2%7D%20%20%5C%5C%20%20%3D%20%20%3E%20x%20-%205%20%3D%2036%20%5C%5C%20%20%3D%20%20%3E%20x%20%3D%2036%20%2B%205%20%5C%5C%20%20%3D%20%20%3E%20x%20%3D%20%2041)
Or,
Square root of x-5=6 is :
![\sqrt{x - 5} \:=\:\sqrt{6}](https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%20-%205%7D%20%5C%3A%3D%5C%3A%5Csqrt%7B6%7D%20)
Answer:
x=19.36111..
Step-by-step explanation:
to get this you would cross multiply
the equation: 36/17=41/x
which you do 36 * x = 17 * 41
divide each side by 36 to cancel it out and leave you with x
giving you (17*41)/36
do this in a calculator...
you get x=19.3611
