The formula of a midpoint between two points:

M\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)

We have:

(5,\ -2)\to x_1=5,\ y_1=-2\\\\(-1,\ 3)\to x_2=-1,\ y_2=3

Substitute:

\dfrac{5+(-1)}{2}=\dfrac{4}{2}=2\\\\\dfrac{-2+3}{2}=\dfrac{1}{2}

Answer: T\left(2,\ \dfrac{1}{2}\right)

Answer:

2.

4x^2 + 4 - 5x + x - 2x^2 + 8

= (4x^2 - 2x^2) + (x - 5x) + (4 + 8)

= 2x^2 - 4x + 12

=> D is correct

3.

2x^2 + 6x - 7x + 8 - 3x^2 + 1

= (2x^2 - 3x^2) + (6x - 7x) + (1 + 8)

= -x^2 - x + 9

=> C is correct

4.

B is correct (4 and 3)

Hope this helps!

Type the correct answer in the box. Use numerals instead of words.
Mandarinka [93]

Answer:

34

Step-by-step explanation:

We are here given a modulus expression and we need to find out the value when m = -5 and n = 3 .

<u>Modulus</u><u> </u><u>:</u><u>-</u> It always gives positive value . For example ,

\rm\implies |-a| = a

\rm\implies |a| = a

<u>The </u><u>given</u><u> </u><u>modulus </u><u>expression</u><u> is</u><u> </u><u>:</u><u>-</u><u> </u>

\rm\implies |m^2+ n^2|

As the number inside the modulus operator are already squared therefore they will always give positive value for real numbers . Here we can omit the modulus .

\rm\implies m^2 + n^2

Plug in the given values ,

\rm\implies (-5)^2 + 3^2

Solve 5² and 3² and add them ,

\rm\implies 25 + 9

On adding ,

\rm\implies 34

Therefore ,

\rm\implies \boxed{\blue{\rm |m^2+n^2| = 34 }}

<u>Hence</u><u> the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>34</u><u> </u><u>.</u>
