Find the coordinate of T' after a 90° counterclockwise rotation of the triangle about the origin and then a translation of 3 units up and 4 units to the left

 c. (0, 5)

Step-by-step explanation:

T = (2, -4)

90° rotation counterclockwise means (x, y) = (-y, x)

new T = (4, 2)

3 units up means add 3 to the y-coordinate

newer T = (4, 5)

4 units left means subtract 4 from the x-coordinate

T' = (0, 5)

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
