Label the slope and y intercept

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol

Which of the following is the graph of y= square root -x-3

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola is (0, –12). the y-intercept of the second parabola is (0, –24). what is the positive difference between the a values for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth
