Answer:
Points on the inverse are
Step-by-step explanation:
When writing the inverse function of a set of points, you simply switch the coordinates:
We are given the points
Using our rule for function, our new points will be
From the list, the points we have for the graph of the inverse are
(-5,1) Because the two reflections make the figure go to the third quadrant. If you have a 180 degree rotation it’ll go back to the second quadrant
C, line equations are not about degrees. Line equation are fill with integers.
Answer:
346 cm²
Step-by-step explanation:
<u><em>Area of square:</em></u>
Area =
A = 20*20
A = 400 cm²
<u><em>Area of rectangle:</em></u>
Length = 3 cm
Width = 20-2 = 18 cm
<u><em>Now, The Area:</em></u>
Area =
Area = 3 * 18
Area = 54 cm²
<u><em>Now, The difference in their areas:</em></u>
=> 400-54
=> 346 cm²
Y is same as the missing angle, the triangle need to equal to 180 so if you add 20 to 60 it equal to 80
use 180 to subtract to 80 you will get the missing x, x=80
