Could someone help me with (Q 15?) Maybe a brainliest if you do step by step and get the correct answer. Thank you :D

For the following equations, find the ratio of a to b. be sure to show all of your work. a. 3a = 6b b. 15a = 5b

The image of abc is a'b'c. what transformations would result in this image? abc is reflected over the line x = 1, then is rotated -90° around the origin. abc is reflected over the line y = x - 1, then t: (x, y) → (x - 1, y - 1). abc is rotated 90° around the origin, then is reflected over the y-axis. abc is rotated -90° around the origin, then is reflected over the line y = -1.

(05.02)how many triangles can be made if two sides are 4 inches and the angle between them is 90°? 1 , 2, more than 2, or none
