Which expression is equivalent to the following complex fraction? StartFraction 2 Over x EndFraction minus StartFraction 4 Over
Harlamova29_29 [7]

The equivalent expression of \frac{\frac 2x - \frac 4y}{-\frac 5y + \frac 3x} is \frac {2(y - 2x)}{ 3y-5x}

<h3>How to determine the equivalent expression?</h3>

The complete question is in the attached image

We have:

\frac{\frac 2x - \frac 4y}{-\frac 5y + \frac 3x}

Take the LCM

\frac{\frac {2y - 4x}{xy}}{\frac{-5x + 3y}{xy}}

Divide through by xy

\frac {2y - 4x}{-5x + 3y}

Rewrite as:

\frac {2y - 4x}{ 3y-5x}

Factor out 2

\frac {2(y - 2x)}{ 3y-5x}

Hence, the equivalent expression of \frac{\frac 2x - \frac 4y}{-\frac 5y + \frac 3x} is \frac {2(y - 2x)}{ 3y-5x}

Find k so that the line through (3,-1) and (k,2) is perpendicular to 2x+3y=6
zalisa [80]
The slopes of perpendicular lines are negative reciprocals.
That means that the product of the slopes of perpendicular lines is -1.

First, we find the slope of the given line.
2x + 3y = 6
3y = -2x + 6
y = (-2/3)x + 6
The slope of the given line is -2/3.

The slope we need is 3/2.
Now we set the slope of the line through the two given points equal to 2/3, and we solve for k.

(-1 - 2)/(3 - k) = 3/2
-3/(3 - k) = 3/2
3/(k - 3) = 3/2
k - 3 = 2
k = 5
