The value of x in the equation \frac{4x}{x - 1} - \frac{5x}{x -2} = \frac{2}{x^2 - 3x + 2} is x = -1 or x = -2

<h3>How to solve the equation?</h3>

The equation is given as:

\frac{4x}{x - 1} - \frac{5x}{x -2} = \frac{2}{x^2 - 3x + 2}

Start by taking the LCM

\frac{4x(x - 2) - 5x(x - 1)}{(x - 1)(x -2)} = \frac{2}{x^2 - 3x + 2}

Expand the denominator

\frac{4x(x - 2) - 5x(x - 1)}{x^2 -3x +2} = \frac{2}{x^2 - 3x + 2}

Cancel out the common factor

4x(x - 2) - 5x(x - 1)= 2

Expand

4x^2 - 8x - 5x^2 + 5x = 2

Evaluate the like terms

-x^2 - 3x = 2

Rewrite as:

x^2 + 3x + 2 = 0\\

Expand

x^2 + 2x + x + 2 = 0

Factorize

x(x + 2) + 1(x + 2) = 0

Factor out x + 2

(x + 1)(x + 2) = 0

Solve for x

x = -1 or x = -2

Hence, the value of x in the equation \frac{4x}{x - 1} - \frac{5x}{x -2} = \frac{2}{x^2 - 3x + 2} is x = -1 or x = -2

GREYUIT [131]

Answer:

The correct answer will be; B or 40.

Step-by-step explanation:

Because when the ratio of boys changed from 8 to 32, it increased by "time 4" (8*4 = 32), so the same pattern will be followed for girls, multiplying the number that you already have by four; 10 (amount of girls given) * 4 = 40.

Hope this helped, Good Luck!

FrozenT [24]

Johnny is selling tickets to a school play. On the first day of ticket sales he sold 14 senior (S) citizen tickets and 4 child (C) tickets for a total of $200. On the second day of ticket sales he sold 7 senior (S) citizen tickets and 1 child (C) ticket for a total of $92. What is the price of one child ticket?

14S + 4C = 200

14S = 200 - 4C

S = (200 - 4C)/14

7S + 1C = 92

7S = 92 - C

S = (92 - C)/7

(200 - 4C)/14 = (92 - C)/7

7 x (200 - 4C) = 14 x (92 - C)

1400 - 28C = 1288 - 14C

1400 - 1288 = 28C - 14C

112 = 14C

C = 112/14 = 8

the price of one child ticket = $8

Please help! I’m not good with y=mb+x
3241004551 [841]

Answer:

m = -4

b = -12

Step-by-step explanation:

First, identify the slope-intercept form:

y = mx + b

y = -4x - 12

Whereas m = slope and b = y-intercept.

Slope is the steepness of the line.

The y-intercept is where the line intersects the y axis.
