Answer:
-2; -7
Step-by-step explanation:
Hello, the graph is split in two lines, right?
Go to the first line at the left and move to the right until you reach the end of the line, which is for x = -1,
*** This is the meaning of x tending to
***
which value can you see for the y-axis? 
Now, go to the second line at the right and move to the left until you reach the end of the line, which is for x = -1,
*** This is the meaning of x tending to
***
which value can you see for the y-axis?

Thanks
Hello!
You first cross multiply
4 * 7 = 28
5 * r = 5 * r
r * 5 = 28
Divide both sides by 5
r = 28/5 = 5.6
The answer is 28/5 or 5.6
Hope this helps!
Usually you use addition to find a sum.
Multiply both 711.9 and 8.4 by 10 which will remove the decimal point.
and make the calculation much more easier
the required answer would be 84.75
<em><u>Polygon:</u></em> a figure formed by coplanar segments
with one distinct interior region
Figure A, Figure B, and Figure D would be considered polygons.
Notice that those figures I mentioned above are
composed of line segments, and nothing else.
In addition, these figures don't have two separate
interior regions and figures that do aren't polygons.
Figure C would not be a polygon because
it's formed by a curve rather than line segments.
