Answer:d=18FT
Step-by-step explanation:
YOUR WELCOM :)
In order to determine whether the equations are parallel, perpendicular, or neither, let's simply each equation into a slope-intercept form or basically, solve for y.
Let's start with the first equation.

Cross multiply both sides of the equation.


Subtract 6x on both sides of the equation.


Divide both sides of the equation by -5.


Therefore, the slope of the first equation is 4/5.
Let's now simplify the second equation.

Add x on both sides of the equation.


Divide both sides of the equation by -4.


Therefore, the slope of the second equation is -5/4.
Since the slope of each equation is the negative reciprocal of each other, then the graph of the two equations is perpendicular to each other.
The Carbon Dioxide in the atmosphere is only very small
relative to other gases. Typically, it only consists about 0.038 percent or
0.04 percent of the gases in the atmosphere.

Even though it is only small, CO2 is very important since it is one of the
greenhouse gases which ensures that the Earth stays warm.</span>
<u>A straight line is 180 degrees in measure</u>
<u>The straight line is made up of three angles</u>
--> angle 1
--> angle 2
--> angle with a little square on it
(<em>angle with a little square means it is 90 degrees in measure)</em>
<u>Let's set up an equation</u>

Thus angle 1 is <u>3 degrees</u> or the <u>second choice</u>

Hope that helps!
I know this is not technically answering your question but there is this app called photomath that I'm pretty sure could help u answer this question. hope if u try out the app it works for you.....
