Answer:

x+10=x^2+2x+1

Step-by-step explanation:

Given equation:

\sqrt{x+10}-1=x

Add 1 to both sides:

\implies \sqrt{x+10}-1+1=x+1

\implies \sqrt{x+10}=x+1

Square both sides:

\implies (\sqrt{x+10})^2=(x+1)^2

\implies \sqrt{x+10}=(x+1)(x+1)

Simplify:

\implies \sqrt{x+10}=x(x+1)+1(x+1)

\implies \sqrt{x+10}=x^2+x+x+1

\implies x+10=x^2+2x+1

Answer:

  x + 10 = x² + 1

(third option listed)

Step-by-step explanation:

assuming that you meant: \sqrt{x+10-1}=x  , because otherwise there would be no equivalent relationships,

(goal: isolate x on one side of the equation whilst having x on the other side of the equation also, like the equation in the question)*

   x + 10 = x² + 1

        -1            -1

   x + 10 - 1 = x²

  \sqrt{x+10-1} =\sqrt{x^2}                  [find √ of both sides to isolate x]

\sqrt{x+10-1} =x         (equation in problem)

       

{note: there's no reason to not simplify the equation to \sqrt{x+ 9, but the question leaves the equation that way, so I didn't simplify it either}

*I used this goal to decide which equations seemed about right, and then trying to test things out in my head

determine the householder transformation that annihilates all but the first entry of the vector [1 1 1 1 ]t. specifically, if (
Stolb23 [73]

Answer:

v=a+ 2e1= [3 1 1 1] x^{T}.

Step-by-step explanation:

Let a = ^{}\left[\begin{array}{ccc}\\1&1&1\\\end{array}\right] ^{T}and we know that\alpha=±║α║₂= 2.

As we have gone over in class, the formula for v is v= a-\alphae1

with the sign of chosen to avoid subtraction. This gives v=a+ 2e1= [3 1 1 1] x^{T}.

60 + 84<br> the sum of the numbers as a product of their GCF is?
Deffense [45]
The sum is the gcf, if 60 plus 84 is 148 then wouldn't it be 148 that's what they all have in common, you can use a calculator to figure this out like say 148 times 2 equals 296, divide 296 by 60. Does it go in?
