What is the x-intercept of the line with this equation 8x−1/3 y=16 ? show your work, and i will mark brainliest!

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20

Solve the triangle. a = 21°, c = 105°, c = 5
