Find the following sets if ℝ is the universal set:
{x∈ ℝ :x2≥ 0}c

R, is the Universal set

Step-by-step explanation:

If x2 < 0 or x3 > 0, then x > 0. Contrapositive: If x2 0 and x3 0, then x 0.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
