As I understand, we need to evaluate the given rational expression, we will get that the evaluated expression is equal to - 1/10

<h3>Evaluating expressions:</h3>

Evaluating an expression just means that we need to replace the variable in the expression for a given value, here we have the expression:

$\frac{3}{2} + (-k) + (-2)$

And we want to evaluate it in:

$k = -\frac{2}{5}$

So we just need to replace k by that value in the above expression, we will get:

$\frac{3}{2} + (-(-\frac{2}{5} )) + (-2)$

Now we can just solve this:

$\frac{3}{2} + (-(-\frac{2}{5} )) + (-2)\\\\\frac{3}{2} + \frac{2}{5} + (-2)\\\\\frac{15}{10} + \frac{4}{10} + (-2) = \frac{19}{10} - \frac{20}{10}= -\frac{1}{10}$

PLEASEEEE HELPPP MEEEE! NOWWWWW

Answer:

The answer is -3

Step-by-step explanation:

First of all we find the difference -4-2 = -(4+2) and than we add the numbers answer is -6 .

$- \frac{6}{4 \div 2}$

4÷2=

$- \frac{6}{2}$

And than we simplify this fraction to 2 and find the answer -3. I would be glad if you choose my answer the best. Good lessons ♡

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (11, 4) → x₁ = 11, y₁ = 4

Point (5, 8) → x₂ = 5, y₂ = 8

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(5-11)^2+(8-4)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-6)^2+(4)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{36+16}$
[√Radical] Add: $\displaystyle d = \sqrt{52}$
[√Radical] Simplify: $\displaystyle d = 2\sqrt{13}$
