Answer:

(-∞, -1/3) U (3, ∞)

Step-by-step explanation:

The given inequality is equivalent to two inequalities (joined with OR).

-3x +7 ≥ 8 . . . . . . eliminate parentheses

-3x ≥ 1 . . . . . . . subtract 7

x ≤ -1/3 . . . . . divide by 3

3x ≥ 9 . . . . . add 1

x ≥ 3 . . . . . . divide by 3

Then the solution to the inequality is the union of these intervals:

x ∈ (-∞, -1/3) ∪ (3, ∞)

Answer:

Two sets are called disjoint if they have no elements in common. For example:

The sets S = { 2, 4, 6, 8 } and T = { 1, 3, 5, 7 } are disjoint.

Another way to define disjoint sets is to say that their intersection is the empty set,

Two sets A and B are disjoint if A ∩ B = 0.

In the example above,

S ∩ T = ∅ because no number lies in both sets.

Answer:

1.1(for infinity) or 0.9

Step-by-step explanation:

it depends if you do 90/100 or 100/90

90/100 = 0.9

100/90 = 1.1(for infinity)

so sorry i couldn't figure out specifically what to divide but i hope both of these answers helped you!
