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

I bet you 10 points you will not answer this<br><br> I think its B i need assurance
Flauer [41]

Answer:

(a) seems to be the closest to being correct of these five statements.

Step-by-step explanation:

Let's go through the list of possible descriptors:

a) There are no outliers.  This seems to be the response most likely to be correct.

b) The distribution is not skewed left.  It's skewed right.

c) The center is not 44.  From what I see, the center is 48.

d) This distribution is not bimodal; it does not have two peaks.

d) The spread is not 38 to 67; it's 29 to 67.

Quadrilateral ABCD is similiar to quadrilateral EFGH. The lengths of the three longest sides in quadrilateral ABCD are 20 feet,
Harman [31]

First, let's list the lengths of the sides in descending order.

Lengths of sides of quadrilateral ABCD: 20, 18, 14, a

Lengths of sides of quadrilateral EFGH: b, c, 6, 5

From the listings above, we see that he sides measuring 14 and 6 are corresponding.

We are looking for c which corresponds to 18.

14 is to 6 is as 18 is to c

14/6 = 18/c

7/3 = 18/c

7c = 3 * 18

7c = 54

c = 54/7 = 7 5/7

Answer: 7 5/7 feet

||x-4|-2|&lt;3 <br> Solve for X
miv72 [106K]

Answer:

x<11

Step-by-step explanation:

x−4(|−2|)<3

Simplifies to:

x−8<3

Let's solve your inequality step-by-step.

x−8<3

Step 1: Add 8 to both sides.

x−8+8<3+8

x<11

Find the inverse of f(x)=−3/2x+7/2.
timama [110]

Answer: f^{-1}(x)=-\frac{2}{3}x+\frac{7}{3}

Step-by-step explanation:

To find the inverse of a function, you want to replace x with y and y with x. Then, you solve for y.

y=-\frac{3}{2}x+\frac{7}{2}                       [replace y with x and x with y]

x=-\frac{3}{2}y+\frac{7}{2}                       [subtract both sides by 7/2]

x-\frac{7}{2} =-\frac{3}{2}y                       [multiply both sides by -2/3]

-\frac{2}{3} (x-\frac{7}{2} )=y                     [distribute]

y=-\frac{2}{3}x+\frac{7}{3}

Now, we have our inverse function.

f^-^1(x)=-\frac{2}{3}x+\frac{7}{3}
