Remember that the radicand (the area under the root sign) must be positive or zero for a radical with an even index (like the square root or fourth root, for example). This is because two numbers squared or to the fourth power, etc. cannot be negative, so there are no real solutions when the radicand is negative. We must restrict the domain of the square-root function.

If the domain has already been restricted to x \geq -11, we can work backwards to add 11 to both sides. We see that x+11 must be under the radicand, so the answer is A.

Find the distance between the two given points. (-6, -5) and (2, 0)
Ipatiy [6.2K]

Answer:

The answer is

<h2>\sqrt{41}  \:  \:  or \:  \:  \: 6.403 \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{( {x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-6, -5) and (2, 0)

The distance is

d =  \sqrt{ ({ - 6 - 2})^{2} +  ({ - 5 - 0})^{2}  }  \\  =  \sqrt{ ({ - 4})^{2}  +  ({ - 5})^{2} }  \\  =  \sqrt{16 + 25}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

\sqrt{41}  \:  \:  or \:  \:  \: 6.403 \:  \:  \: units

Hope this helps you

3x=5x-9 pls help ?!!?!?!?!?!?!?!?!??!!?1/
lbvjy [14]

Answer: x = 4.5

Step-by-step explanation:

1) Reorder the terms:

3x = -9 + 5x

2) Solving

3x = -9 + 5x

3) Solving for variable 'x'.

4) Move all terms containing x to the left, all other terms to the right.

5) Add '-5x' to each side of the equation.

3x + -5x = -9 + 5x + -5x

6) Combine like terms: 3x + -5x = -2x

-2x = -9 + 5x + -5x

7) Combine like terms: 5x + -5x = 0

-2x = -9 + 0

-2x = -9

8) Divide each side by '-2'.

x = 4.5

9) Simplifying

x = 4.5
