Answer:
F(-7,3) -> F'(-7,-3)
G(2,6) -> G'(2,-6)
H(3,5) ->H'(3,-5)
Step-by-step explanation:
If you are taking point (a,b) and reflecting it across the x-axis (the horizontal axis), your x value is going to stay the same because you want the point on the same vertical line as (a,b). The y-coordinate is going to be opposite because you want a reflection and the opposite of b will this give you the same distance from the x-axis as b.
So the transformation is this: (a,b) -> (a,-b).
All this means is leave x the same and take the opposite of y.
F(-7,3) -> F'(-7,-3)
G(2,6) -> G'(2,-6)
H(3,5) ->H'(3,-5)
Answer:





Step-by-step explanation:

As both
,
lies in the third quadrant.
In the third quadrant,






20 x 20 = 400
4(1/2 x 20 x 30) = 1200
400 + 1200 = 1600
So, D
Answer:
X-coordinate = 3
Step-by-step explanation:
2x - y = 6
<u> x + y = 3 </u>
3x = 9
3x/3 = 9/3
x = 3
2 (3) - y = 6
6 - y = 6
-y = 6 - 6
y = 0
( 3, 0 )
3 is the x-coordinate of your solution.
