When 2 less than 3 lots of a number is doubled the result is 5

What is the upper quartile in the box plot?

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

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1
