What is the ratio 5 to 105 expressed as a fraction in simplest form?

If f(x)=x^3 and g(x)=2x+7 when g(x)=-5

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

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
