Solve the equation 3x + 4 = 5x - 8​
CaHeK987 [17]

Answer:

x = 6

Step-by-step explanation:

3x + 4 = 5x - 8

==> add 8 to both sides

in doing so we get 3x + 4 + 8 = 5x - 8 + 8

the -8 and the +8 cancels out and 4 + 8 = 12

we are left with 3x + 12 = 5x

==> subtract 3x from both sides

in doing so we get 3x - 3x + 12 = 5x - 3x

the 3x and -3x cancel out and 5x - 3x = 2x

we are left with 12 = 2x

==> divide both sides by 2

in doing so we get 12/2 which equals 6 and 2x/2x which leaves us with

6 = x

Which of the following is written as a rational function?
Brrunno [24]

We have to identify the rational function among the given functions.

Rational function is a function that is the ratio of two polynomials. It is rational because one polynomial is divided by the other polynomial, like a ratio.

1. Consider the first function G(x)= -2x, since it is not a function that is the ratio of two polynomials. So, it is not a rational function.

2. Consider the second function P(x)= 3x+4, since it is not a function that is the ratio of two polynomials. So, it is not a rational function.

3. Consider the third function Q(x)= x^2-8x+1, since it is not a function that is the ratio of two polynomials. So, it is not a rational function.

4. Consider the fourth function F(x)= \frac{x+2}{5x}, since it is a function that is the ratio of two polynomials (x+2) and (5x). So, it is a rational function.

So, Option D is the correct answer.
