Answer:
(-7,2)
Step-by-step explanation:
The point (7,-2) when reflected across the x-axis becomes (7, 2). When it is reflected across the y-axis it becomes (-7,2). You can find this because when a point is reflected across the x-axis, its y-coordinate changes its sign. The same is true when reflected across the y-axis. It's x coordinate changes its sign.
A double reflection across both axis changes the sign of each coordinate.
Answer:
12 visits to a free movie ticket
Step-by-step explanation:
224 points for a free ticket - 50 she has for signing up = 174 points needed

A plot of the points shows the polygon is a square with side length 3 units. The area is ...
... 3 units × 3 units = 9 square units
STEP 1:
Triangles= 180°
Other Angles= 7:13= 7x + 13x
Add all the angles to equal 180°
140° + 7x + 13x= 180°
combine like terms
140° + 20x= 180°
subtract 140 from both sides
20x= 40
divide both sides by 20
x= 2
STEP 2:
substitute x value to find other two angles
7x= 7(2)= 14° one angle
13x= 13(2)= 26° other angle
CHECK:
140° + 14° + 26°= 180°
140 + 40= 180
180= 180
ANSWER: The other two angles measure 14° and 26°.
Hope this helps! :)
