For a right triangle, the two shorter sides (the legs a and b) squared must add up to equal the longest side (the hypotenuse or c) squared. This is the pythagorean theorem:

a squared + b squared = c squared

If you try all the sets in the pythagorean theorem equation, 20, 21 and 29 are the only ones that work out, so that would be the answer.

Which of the following is a solution of y - x < -3?

Mariulka [41]

Answer:

Option A. (6,2)

Step-by-step explanation:

We have the following inequality:

$y- x$

Solving for y we have:

$y$

The line that limits the region of inequality is

$y = x-3$

Then the region of inequality are all values of y that are less than $f (x) = x-3$

In other words, the points belonging to the inequality are all those that lie below the line.

To find out which point belongs to this region substitute inequality and observe if it is satisfied

A. (6,2)

$2$

$2$ <em> is satisfied</em>

B. (2, 6)

$6$

$6$ <em>it is not satisfied</em>

C. (2, -1)

$-1$

$-1$ it is not satisfied

<em>The answer is the option A</em>
