Use a graphical method to find the solution(s) to the equation x³ - 4x² + x + 2 = 0 -15 -10 -5 15 10 5 0 -5 -10 -15 0 5 10 15

please give me a step by step solution for the following problem: 6(-9)-(-8)-(-7)(4)+11

Why is the sum of the square roots of positive numbers always greater than the square root of their sum, but the sum of two squared numbers always less than the square of the sum of those same two numbers?

3) Without graphing, determine the number of solutions for Sy-3x = 6 (3y - 9x = 18

X(3x-7)=0 is what . Can you please solve this

Two students, James and Joe were solving the equation 6-5(11-2x) = 17x. Their work is shown below for questions 2 - 5. James' Work 6-5(11-2x) = 18x 6-5(11-2x) =18x 6 6 -5(11-2x) = 3x -55 + 10x = 3x -10x10x -55 = -7x -7 -7 7 = = x J:SC Joe's Work 6-5(11-2x) = 17x 6-55 +10x = 17x -49 + 10x = 17x -10x10x : -49 = -7x -7 -7 7=x first stop the students used in solving the equation.
