Find the term that must be added to the equation x2−10x=1 to make it into a perfect square

adoni [48]

Answer:

25

Step-by-step explanation:

If you add 25 to both sides, you get

x^2-10x+25=26.

Now, you can simplify the left side into a perfect square

(x-5)^2=26

How do you get figure 1 to 2?

Hatshy [7]

Do this on paper, please.
First, rotate the larger rectangle about the origin so that it ends up being a vertically-oriented rectangle in the fourth quadrant (next to the smaller rectangle). What would you then have to do to this large, vertical rectangle so that it has the same size and shape as does the small vertical triangle?

20 POINTS~<br><br> 2/5 |5x+10| -14 > -6<br> Please explain both answers

Pavlova-9 [17]

Answer:

$x2$

Step-by-step explanation:

We have the inequality:

$\frac{2}{5}|5x+10|-14>-6$

First, we can factor out a 5 from our absolute value. This yields:

$\frac{2}{5}(5|x+2|)-14>-6$

Simplify:

$2|x+2|-14>-6$

Add 14 to both sides:

$2|x+2|>8$

Divide both sides by 2:

$|x+2|>4$

Definition of Absolute Value:

$x+2>4\text{ or } -(x+2)>4$

Solve each case individually:

Case 1:

$x+2>4$

Subtract 2 from both sides:

$x>2$

Case 2:

$-(x+2)>4$

Divide both sides by -1. Flip the sign:

$x+2$

Subtract 2 from both sides:

$x$

So, our answers are:

$x2$

Since our inequality is a <em>greater than</em>, we will have an "or" inequality.

So, our answer is all values left to the first solution and all values to the right of the second solution:

$x2$

And we're done!

3/4x-4/5=1/2x+1 what is x?

Afina-wow [57]

<span>3/4x - 4/5 = 1/2x + 1

</span>3/4x - 4/5 = 2/4x + 1

3/4x - 2/4x = 1 + 4/5

1/4x = 9/5

x = (9x4) / (5x1)

x = 36/5

x = 7 1/5
