Solve and graph the compound inequality. s + 4 > 4.5 or −3 + s ≤ −10

s > −7 or s ≤ 0.5

s > 0.5 or s ≤ −7

(hurry! ) which expression is equivalent to the following complex fraction?

One positive number is 9 more than twice another. if their product is 95, find the numbers

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
