Question

(1.)Express the solution set of the inequality in set notation. x + 5 ≤ 9 ( 2.) Express the solution set of the equation in set notation. x - 2 = 10

(3.)Write a sentence to express the solution set in words. w + 9 > 10

Answer 1

Explanation:

1.

x+5≤9

x≤4

(-∞,4]

2.

x-2=10

x=12

x∈ [2]

3.

w+9>10

w>1

solution is all real values greater than one.
