if y varies inversely as x and has the value 3/8 when x is equal to 10, what is the value of y when x is equal to 8/9?

Complete the statements about the system of linear equation respresented by the tables the equation respented the left table is

The parabola opens: y=√x-4 (principal square root) up down right left

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
