Answer:
Step-by-step explanation:
15x + 12 + 10 - 20 = 12
15x + 22 - 20 = 12
15x + 2 = 12
15x = 12 - 2
15x = 10
x = 10/15 which reduces to 2/3
The union and intersection of the sets is given as { -4, -9 , 19} and { -4} respectively.
<h3>What is a set?</h3>
A set is simply a mathematical model for a collection of different things which could be elements or members.
Union of sets represented with '∪' is the combination of two sets without repetition
Intersection of sets represented with '∩' is the sum of elements common between the.
From the expression given, we have;
[-9,-4] U (-4, 19)
= { -4, -9 , 19}
[-9,-4] U (-4, 19)
= { -4}
Thus, the union and intersection of the sets is given as { -4, -9 , 19} and { -4} respectively.
