Answer:

Yes

Step-by-step explanation:

In mathematics, a rational number is a number such as -3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Every integer is a rational number: for example, 5 = 5/1.

An Irrational ia (of a number, quantity, or expression) not expressible as a ratio of two integers, and having an infinite and nonrecurring expansion when expressed as a decimal. Examples of irrational numbers are the number π and the square root of 2.

Rational numbers include natural numbers, whole numbers, and integers. They can all be written as fractions. Sixteen is natural, whole, and an integer. Since it can also be written as the ratio 16:1 or the fraction 16/1, it is also a rational number.

In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.

So, it is rational

Answer:

See below.

Step-by-step explanation:

The converse of the Pythagorean Theorem tells us that if the sum of the square of the two shorter lengths is equivalent to the square of the longest length, then the triangle is indeed a right triangle.

We have the side lengths (x²-1), (2x), and (x²+1).

We can see that our hypotenuse will be (x²+1), since it will always yield the largest value for x.

So, we can use the Pythagorean Theorem:

a^2+b^2=c^2

Substitute (x²-1) and (2x) for a and b, and substitute (x²+1) for c:

(x^2-1)^2+(2x)^2\stackrel{?}{=}(x^2+1)^2

Square each expression:

(x^4-2x^2+1)+(4x^2)\stackrel{?}{=}(x^4+2x^2+1)

Combine like terms:

x^4+(-2x^2+4x^2)+1\stackrel{?}{=}(x^4+2x^2+1)

Add:

x^4+2x^2+1\stackrel{\checkmark}{=}x^2+2x^2+1

We can see that the resulting equations are equivalent, proving that the triangle is indeed a right triangle.

And we're done!

erik [133]
First, substitute.

-9 = 2(-2) - 5
-9 = -4 -5
-9 = -9
Yes, the point (-2, -9) satisfies the equation
