Answer: None

Step-by-step explanation:

You have to either solve for x or y by getting x/y in both equations the same value to cancel them out. In my steps I will solve for x:

-20x - 16y = -20

10x + 8y = 10

----------

<u>1.) Multiply 10x + 8y = 10 by 2</u>

-20x - 16y = -20

20x + 16y = 20

<u>2.) Cancel out values</u>

All parts cancel out.

Step-by-step explanation:

F(5)

5 > 2 so you plug the 5 into 3x+2

F(-2)

-5 < -2 < 2 so you plug the -2 into (x-2)^2

<h3>Answer:</h3>

y=1/2x

<h3>Solution:</h3>

The slopes of perpendicular lines are opposite reciprocals of each other.
The simplest way to determine a number's reciprocal is to flip it over, like so:
$-2 ~ - > -\displaystyle\frac{1}{2}$
Now, change the sign:
$\displaystyle\frac{1}{2}$
So we have the <em>slope </em>of the line that's <em>perpendicular </em>to the given line.
Now, let's find the line's equation.
First, let's write it in Point-Slope Form:
y-y1=m(x-x1)
y-(-2)=1/2(x-4)
y+2=1/2x-2 (Point slope)
Now, convert to slope-intercept:
y=1/2x+2-2
y=1/2x
