Let us study the following examples- (i) (2+3)+4
2 +(3+4)
5+ 4
= 2 + 7
9
= 9
(ii) (-2+3) + 5
-2 + (3 + 5
1 + 5
= 2 + 8
6
6
(iii) (-2 + 3) + (-5) = (-2) + [3 + (-5)]
= (-2) + (-2)
4
1 +(-5)
-4
(iv) [(-2)+(-3)] + (-5)
-5+(-5)
-2 + [(-3) + (-5)]
-2+(-8)
-10
= -10

The coordinates of vortex a’ are (8,4) (-4,2) (4,-,4) the coordinates of vortex b’ are (6,6)(12,-,12)(12,12) the coordinates of vortex c’ are(-2,,12)(4,12)(12,-4)

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
