1. Solve the rational equation quantity 4 times x plus 3 end quantity divided by 5 equals quantity 8 times x minus 1 end quantit

Vladimir [108]

Answer:

1. x = 8

2. $x=-\dfrac{3}{2}$

Step-by-step explanation:

1. Solve the rational equation

$\dfrac{4x+3}{5}=\dfrac{8x-1}{9}$

First, cross multiply:

$9(4x+3)=5(8x-1)$

Now, use distributive property:

$36x+27=40x-5$

Separate terms with x and without x into different sides of equation:

$36x-40x=-5-27$

Simplify:

$-4x=-32$

Divide by -4:

$x=8$

2. The rational function

$f(x)=\dfrac{x-4}{2x+3}$

This rational function is undefined for all values of x, for which the denominator is equal to 0. Find these values:

$2x+3=0\\ \\2x=-3\\ \\x=-\dfrac{3}{2}$

This means that the line $x=-\dfrac{3}{2}$ is a vertical asymptote for the rational function f(x).

Use the given function to evaluate for the given value of x

Jet001 [13]

Answer:

32/13.

Step-by-step explanation:

Just substitute the value of x inside the respective functions. I assume you are asking for help in question 9 as you said "the given function"!

f(x) = (3x^2 + 2x - 1) / (4x + 1)

So f(3) = (3 * 3^2 + 2 * 3 - 1) / (4 * 3 + 1)

= (27 + 6 - 1) / (12 + 1)

= 32 / 13.
