$D:k-9\geq 0 \wedge k\geq0\\
D:k\geq 9 \wedge k\geq0\\
D:k\geq 9\\
\sqrt{k-9}-\sqrt k=-1\\
\sqrt{k-9}=-1+\sqrt k\\
k-9=(-1+\sqrt k)^2\\
k-9=1-2\sqrt k+k\\
2\sqrt k=10\\
\sqrt k =5\\
k=25

If x=2k + 1, y=k - 1 is a solution of the equation 2x - 3y + 5=0. find the value of k.

devlian [24]

Answer:

$x = 2k + 1 \\ y = k - 1 \\ given$

if u substitute the givens in the eqn we will get..

$2(2k + 1) - 2(k - 1) + 5 = 0 \\ 4k + 2 - (2k - 2) + 5 = 0 \\ 4k + 2 - 2k + 2 + 5 = 0 \\$

then collect like terms

$4k - 2k + 2 + 2 + 5 = 0 \\ 2k + 4 + 5 = 0 \\ 2k + 9 = 0$

$2k = - 9 \\ k = \frac{ - 9}{2}$
