What is 5x-9 > 11 i need the whole anderr

x ≥ 4

Step-by-step explanation:

Start with: 5x - 9 ≥ 11

Add 9 to both sides: 5x - 9 + 9 ≥ 11 + 9

Divide both sides by 5:

Simplify: x ≥ 4

Since you are not dividing both sides by a negative number, the greater than or equal to sign faces the same direction.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

(x+3)(x+7)
