Assume that y varies directly with x. If y=1/4 when x=1/8, find x when y=3/16. Enter in any fractions using a / (e.g. "1/2" is t

he same as 12).

Answer:

3/32

Step-by-step explanation:

Whatever you do to y always happens to x right? I'm REALLY new to this question so i'm not really sure so wait for more responses if needed.

The slope-intercept form given (6,-5) & perpendicular to -5x - 7y = -17.

tatuchka [14]

Answer:

$y=\dfrac{7}{5}x-\dfrac{67}{5}$

Step-by-step explanation:

<u>Slope-intercept form of a linear equation:</u>

$y=mx+b$

where:

m is the slope.
b is the y-intercept.

<u>Rearrange</u> the given equation so that it is in <u>slope-intercept form</u>:

$\implies -5x-7y=-17$

$\implies -7y=5x-17$

$\implies y=-\dfrac{5}{7}x+\dfrac{17}{7}$

Therefore, the slope of the given equation is -⁵/₇.

If two lines are <u>perpendicular</u> to each other (at right angles), the <u>product of their slopes</u> will be -1. Therefore, their slopes will be negative reciprocals of each other.

Therefore, the slope of the line perpendicular to the given equation is:

$\sf m=\dfrac{7}{5}$

<u>Substitute</u> the found <u>slope</u> and the <u>given point</u> (6, -5) into the <u>slope-intercept formula</u> and solve for b:

$\implies -5=\dfrac{7}{5}(6)+b$

$\implies -5=\dfrac{42}{5}+b$

$\implies b=-\dfrac{67}{5}$

<u>Substitute</u> the found slope and the found value of b into the <u>slope-intercept formula</u> to create the equation for the <u>perpendicular line</u>:

$\implies y=\dfrac{7}{5}x-\dfrac{67}{5}$

The value of the output r(-3) in the given function is 2.

<h3>How to Interpret Graphs?</h3>

When we talk about graphs like this, it is pertinent to note that the x-values are the input values which would give us corresponding y-values which are the output values.

Now, we want to find r(-3) from the graph. This means we want to find the value on the y-axis when x = -3.

From the given graph, we see that when x = - 3, it is traced that the value of the output is y = 2.

Thus, the value of the output r(-3) in the given function is 2.
