Which of the following statements are true about the given rational equation? check all of the boxes that apply. 4 x 6 1 x2 = x
Agata [3.3K]

We can actually see that the statements that are true are:

A. x = 1 is a solution.

C. x = –1 is a solution.

<h3>What is rational equation?</h3>

Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.

We can see then that:

\frac{4}{x + 6}  +  \frac{1}{ {x}^{2} }  =  \frac{x + 10}{ {x}^{3} + 6 {x}^{2}  }

It's clear that: x ≠ 0 and x ≠ -6.

Looking for the LCM of the left hand side, we will have:

\frac{4}{x + 6}  +  \frac{1}{ {x}^{2} }  =  \frac{4 {x}^{2 }  + (x + 6)}{(x + 6) {x}^{2} }

So, we will see that left hand side and right hand side are equal.

4 {x}^{2}  + x + 6 = x + 10

4 {x}^{2}  = 10 - 6

4 {x}^{2}  = 4

{x}^{2}  = 1

x = 1

or

x =  - 1

So, we can see that options A and C are correct.

How do you turn -3 1/3 into a negative fraction decimal
lina2011 [118]
Dear Joanna243,  what do you mean by a "negative fraction decimal". You can't have a fraction and a decimal at the same time. I'll solve it anyway. Take 1/3 and do 1÷3 to get approximately 0.33, then you plug the -3 with 0.33 to get -3.33

What are the independent and dependent quantities?
Anit [1.1K]

There are two types of variables-independent and dependent. Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

Hope this helps! :)
