Apply dilation (x, y) ---> (2/3x, 2/3y) to A(6,-3) B(3,-3) C(0,0)

Please find new coordinates

Find the zeros of the function. write the smaller solution first, and the larger solution second f(x)= (x+6)^2-49

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

Bring the fraction a/a-4 to a denominator of 16-a^2
