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).

Please help (CORRECT ANSWERS ONLY)

german

-2(8m+8) = -16

-16m - 16 = -16

His first mistake lies in his distribution. When multiplying -2 * 8, he made it a positive 16, when he should have made it a negative 16.

-16m - 16 = -16

Add 16 to each side.

-16m = 0

Divide that by -16

m = 0

I need some help here plz

Answer:

I don't know if this is correct but id say

$5500 \times \frac{2}{100} = 55 \times 2 = 110$

Step-by-step explanation:

the interest is 2 % so you'd say 2/100 times the amount of money in the interest so that is 2% of 5500

the interest is 110
