Help! I need help with this question. I'm not sure how to do it. Would appreciate any help you can offer.

1 answer:

6 0

A)
We first set up the ratio given
36 : 100
Using this,
0.36 butterflies for every 1 flying insect
13 butterflies for every 50 flying insects
36 butterflies for every 100 flying insects

B)
36 : 100
x : 450
x = 450 x 36 / 100
x = 162 butterflies in the conservatory.

Putting the equations in slope-intercept form changes the system from

myrzilka [38]

$15x+9y=36 \rightarrow y=-\frac{5}{3}x+4 \\ \\ 10x + 6y = 36 \rightarrow y=-\frac{5}{3}x+6$

The lines are parallel.

The slopes are equal.

<h2>Explanation:</h2>

The standard form of the equation of a line is given by the form:

$Ax+By=C \\ \\ \\ Where: \\ \\ A \ is \ a \ positive \ integer \\ \\ B,C \ are \ integers$

On the other hand, the slope-intercept form of the equation of a line is given by the form:

$y=mx+b \\ \\ \\ m:Slope \\ \\ b:y-intercept$

So let's convert each equation from the standard form to the slope-intercept form:

So, for the first equation:

$15x+9y=36 \\ \\ Solving \ for \ y: \\ \\ 9y=-15x+36 \\ \\ y=\frac{-15x+36}{9} \\ \\ y=-\frac{5}{3}x+4$

So, for the second equation:

$10x + 6y = 36 \\ \\ Solving \ for \ y: \\ \\ 6y=-10x+36 \\ \\ y=\frac{-10x+36}{6} \\ \\ y=-\frac{5}{3}x+6$

As you can see both equations have the same slope but different y-intercepts meaning that they are parallel. So these are the correct options:

The lines are parallel.

The slopes are equal.
