For all your graphing needs: www.desmos.com/calculator 
This calculator works really well and sometimes seeing how something is graphed physically and comparing the graph to the equation helps more than an explanation.

Hope this helps!! (:

Basically
graph y=x+4
wherever the line goes under the x axis, reflect that part across the x axis to make it positive
now find which part to shade
(0,0) is an option so shade down

so

find where it equals 0 or where it tursn negative
at x=-4

so graph y<x+4 from x=-4 to x=infinity
grahp y<-x-4 from x=negative infinity to -4

then shade under that
use dotted lines

Write the equation of the line that contains (-4, -3) and is parallel to the line x+2y=-10
Vikentia [17]
<h2>Introduction</h2>

Hello! I hope you are having a nice day. My name is Galaxy and I will be helping you with this problem. We can solve this problem in 2 steps, respectively Theory and Solving.

I'll go ahead and start with the Theory.

<h2>Theory</h2>

Before we attempt to solve the problem mathematically, we must first figure out how we're going to solve this problem.  

We know that we have a line and a point, we can start by graphing the equation and point that we've received.

<h2 /><h2>Solving</h2>

Now that we have our points plotted and our equations graphed, we can start to see that something odd is happening, the given point is on the line itself.

We can check this by inputting the points into our equation:

(-4)+2(-3)=-10?\\(-4)+(-6)=-10?\\-10=-10

This proves that our point is on the line that we were given.

According to the basic rules of Euclidean Geometry, we know that parallel lines can never intersect each other and due to this there cannot be any solution to this problem.

Any other line using this point would intersect the given line, and due to this, this problem has no real solutions.

* The only line that can use these points and graph is the line provided, and that cannot work due to the lines intersecting at an infinite number of points.

Cheers,
Galaxy.

Two rectangles are similar. The length and width of the first rectangle is 4 m by 5 m. The second rectangle is similar by a scal
likoan [24]
<h3>Answer:  320 square meters</h3>

===================================================

Explanation:

The scale factor 4 means the dimensions of the second rectangle are 4 times larger.

The width of 4 meters bumps up to 4*4 = 16 meters.

The length of 5 meters becomes 4*5 = 20 meters.

So a 4 by 5 rectangle is similar to a 16 by 20 rectangle.

The area of the second rectangle is therefore 16*20 = 320 square meters.

---------------

As an alternative, you can compute the area of the 4 by 5 rectangle to get 4*5 = 20. Then multiply this with 4^2 = 16 to get 16*20 = 320.

The 4^2 = 16 multiplier is the result of squaring the scale factor.

So if you know the dimensions have been multiplied by 4, then the area has been multiplied by 16.
