Describe the graph of the solution of x+3≤4. By solving the inequality to obtain x≤ , the graph has circle at and an arrow pointing in the direction.

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

According to the data set, where should the upper quartile line of the box plot be placed?
