Solve the inequality. 1/2 + x + 1/6 is greater than or equal to 1.

1/2 + x + 1/6 > = 1

First add the 2 fractions:

1/2 + 1/6 = 2/3

Now you have:

2/3 + x > =1

Subtract 2/3 from both sides:

x >= 1 - 2/3

X > = 1/3

a

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
