The equivalent sets are <u>X n Y = { } and X U Y= {5, 6, 7,8, 9, 10, 12 ,14}</u>
<h3>Set theory and notation</h3>
Given the following sets expressed as;
X = {8, 10, 12, 14}
Y = {5, 6, 7, 8,9}
Since union means the combination of all the elements in both sets and intersection is the common elements in the set, hence;
X n Y = { }
X U Y= {5, 6, 7,8, 9, 10, 12 ,14}
Note that the intersection is an empty set since there is no common element

The slope would be 2. to find slope use the formula attached.
Answer:
60
Step-by-step explanation:
(2x+15)=135 They're corresponding angles so they equal/congruent
<u> -15 -15</u> Subtract 15 on both sides since you're looking for x
<u>2x</u> = <u> 120</u> Bring down the remains and subtract 135 from 15
2 2 Add 2 on both sides
x= 60 Divide.
Answer:
The correct answer will be X = 4
Step-by-step explanation:
Using Pythagoras
AB^2 + BC^2 = AC^2
2^2 + (2√3)^2 = AC^2
4 + (4*3) = AC^2
4+12 = AC ^ 2
AC ^2 = 16
AC = √16 = 4
Answer:
Option A. is correct.
Step-by-step explanation:
Given: A cell phone company recently noticed a 
sales decrease in the month of July compared to June such that 
represent June's sales.
Also, 
represents July's sales.
To find: equation that can be used to determine the sales in July
Solution:
June's sales 
Decrease in sales 
So,
July's sales 
Also,
July's sales 
Therefore,
So, option A. is correct.
