I need help with these pre-calculus questions. Please provide a step process/explanation for each question. Thank you so much!

\f10.) Find the slope between (-2, 5) and ( 6, 9) (1.) Find the 4-intercept for y=x- 5x2+ 2 12. ) Find the X-intercept for y= 3x-12 13. ) Apply the Pythagorean Theorem to find the value of "c" if a= 9 and b= 12. 14. ) Simplify 120 15. ) Apply the Quadratic Formula to x + 3 x-5 2 16. ) FACTOR x + 2x - 24 7. ) Factor 3x + 11 x + 10 18.) Factor x - 16 19.) FACTOR x + 27 20.) multiply x (x+ 2 ) (x + 5 ) 21. ) Solve 2x+ 9 = 9 x - 4 : 3
