Answer:

There are no solutions

Step-by-step explanation:

As far as I'm aware—and I could be wrong, so take my word with a grain of salt—the answers listed should contain equations instead of just values. If they were just values, they would be directly vertical and horizontal. These lines have slopes though, so you would need an equation. The question's worded in a strange way, I don't really know for certain but this is what I'd say is the safest answer.

Find the length of side x in simplest radical form with a rational denominator.
Leto [7]
<h3>Answer:  2\sqrt{5}</h3>

======================================================

Explanation:

Both legs are the same length, as indicated by the tickmark.

  • a = \sqrt{10}
  • b = \sqrt{10}
  • c = x

Use the pythagorean theorem to solve for x

a^2+b^2 = c^2\\\\( \sqrt{10} )^2 + ( \sqrt{10} )^2 = x^2\\\\10 + 10 = x^2\\\\x^2 = 20\\\\x = \sqrt{20}\\\\x = \sqrt{4*5}\\\\x = \sqrt{4}*\sqrt{5}\\\\x = 2\sqrt{5}\\\\

Which statement is true about the function f(x)= StartRoot negative x EndRoot?
UNO [17]

Answer:

The domain of the graph is all real numbers less than or equal to 0

Step-by-step explanation:

we have the function

f(x)=\sqrt{-x}

we know that

The radicand must be positive

so

-x \geq 0

Solve for x

Multiply by -1 both sides

x\leq 0

The domain is the interval ------> (-∞,0]

All real numbers less than or equal to zero

The range of the function is the interval -----> [0,∞)

f(x)\geq 0

see the attached figure to better understand the problem

All real numbers greater than or equal to zero

<em><u>Verify each statement</u></em>

case 1) The domain of the graph is all real numbers

The statement is false

Because, the domain is all real numbers less than or equal to zero

case 2) The range of the graph is all real numbers

The statement is false

Because, the range is all real numbers greater than or equal to zero

case 3) The domain of the graph is all real numbers less than or equal to 0

The statement is true

case 4) The range of the graph is all real numbers less than or equal to 0

The statement is false

Because, the range is all real numbers greater than or equal to zero

Angles M and N are complementary. The measure of M is 27°. What is mN?
finlep [7]

Answer:

A. 63 degrees

Step-by-step explanation:

Complementary angles are angles that add up to 90 degrees. You can make an equation to solve for angle N:

27 + x = 90

rearrange the equation:

90 - 27 = x

63 = x
