3x+5y=10 and 5x-3y=-6 is perpendicular.
A is correct, D, And E.....
Answer:
A'(7,-3)
Step-by-step explanation:
We were given the coordinates, A(-7,3) of quadrilateral ABCD and we want to find the image of A after a reflection across the x-axis followed by a reflection in the y-axis.
When we reflect A(-7,3) across the x-axis we negate the y-coordinate to obtain: (-7,-3).
When the image is again reflected in the across the y-axis, we negate the x-coordinate to get (--7,-3).
Therefore the coordinates of A' after the composed transformation is (7,-3).
We can find the volume of one of the cubes, then multiply by 3996 to find the total volume.
The edge lengths are 1/3, so the area of one cube is:
(1/3)^3 = 1/27
The area of the prism is:
3996 * (1/27) = 148 in^3
False because the data would go more apart than closer
