The best explanation is: If you were to follow the instructions,
then the answer would jump out at you.

The first word on the page tells you to GRAPH the equations.
You didn't do that. You read that, and you said to yourself
"Self ! You don need to do dot." so of course you're having
trouble finding the answer.

When you GRAPH the two equations, you'll find that you have
two straight lines on the graph, and they're parallel. Whatever
point you pick on the upper line, the lower line is ALWAYS exactly
9 units below it. The lines are never closer together, and they're
never farther apart. Always exactly 9 units.

The lines never cross anywhere.

A "solution" to the system is a point where the lines cross.

There isn't any.

Whats the value of 1¹²

velikii [3]

Step-by-step explanation:

Answer is 1, because, your multiplying 1 12 times, so it is

1*1*1*1*1*1*1*1*1*1*1*1=1

even if it was 1 to the power of 100, it's still going to be 1, if the base number is 1, then exponent can be any number and still getting 1.

Square root of the quantity x minus 2 end quantity plus 8 equals x

Butoxors [25]

ANSWER

x=11

EXPLANATION

We want to solve the equation:

$\sqrt{x - 2} + 8 = x$

Add -8 to both sides:

$\sqrt{x - 2} = x - 8$

Square both sides of the equation to get:

$(\sqrt{x - 2} )^{2} =( x - 8)^{2}$

$x - 2 = {x}^{2} - 16x + 64$

Rewrite in the form ax² +bx+c=0

${x}^{2} - 16x - x + 64 + 2 = 0$

${x}^{2} - 17x + 66 = 0$

Factor to get,

$(x - 11)(x - 6) = 0$

This implies that,

$x = 11 \: or \: x = 6$

Checking for extraneous solutions.

When x=6, the original equation becomes,

$\sqrt{6- 2} + 8 = 6$

$\sqrt{4 } + 8 = 6$

2+8= 6 is not true.

x=6 is an extraneous solution.

When x=11, the original equation becomes,

$\sqrt{11- 2} + 8 = 11$

$\sqrt{9} + 8 = 11$

$3 + 8 = 11$

This is true, hence x=11 is the only solution.
