The first one
Step-by-step explanation:
Test them
Answer:
The quadrilaterals will be congruent
The quadrilateral will now appear in Quadrant 2
Step-by-step explanation:
Given
Rotation across 180 degrees
Reflection across y-axis
Required
The true statement
Using point W as a point of reference; We have:
1. Rotation across 180 degrees
The rule is:
So:
2. Reflection across y-axis
The rule is:
So:
Using the above transformation on the other points; We have:
Plot the above points on a grid (see attachment).
<em>From the grid, we can conclude that: the quadrilaterals will be congruent , and it will appear in Quadrant 2.</em>
Answer:
-12x+12
Step-by-step explanation:
8-20x+12-4+8x-4
-12x+12
The unit cost decreases the more you buy at once. 1.10/1 = $1.10 you're paying $1.10 per 1. 1.98/2 = $ .99 you're paying $.99 per 1 2.89/3 = $.96 you're paying $.96 per 1. When you buy 9 you're paying less per 1 than you are when you buy 1
∡3 and ∡7 are corresponding angles, so m(∡3) = m(∡7) = 115°
∡7 and ∡5 are verically opposite angles, so m(∡7) = m(∡5) = 115°
