Answer:
n(A) = 3
n(B) = 6
-6 ∈ A => True
-14 ∈ A => False
k ∈ B=> True
Q∈B = >False
Step-by-step explanation:
Given
A is the set of integers greater than - 7 and less than - 3
B={c, h, j, k, v, y}
For set A:
The integers greater than -7 will be -6,-5 ....
As the set has integers less than -3, the set will be:
<u>Cardinalities:</u>
Cardinality is the number of elements in the set.
So,
Now for the statements:
-6 ∈ A True as -6 is a member of set A
-14 ∈ A False as -14 is not a member of A
k ∈ B True
Q∈B False
Hence,
n(A) = 3
n(B) = 6
-6 ∈ A => True
-14 ∈ A => False
k ∈ B=> True
Q∈B = >False
20% of 150 is 30
Change the percentage into a decimal by dividing it over 100:
20 / 100 = 0.2
Multiply:
0.2 × 150 = 30
Step-by-step explanation:
Remember: the formula for solving for volumes:
l • w • h
An easy way to do this is to convert all the numbers to decimals.
3 1/2 = 3.5
5 1/4 = 5.25
4 = 4
Now, we can multiply.
3.5 • 5.25 • 4 = 73.5
Convert 0.5 to a fraction: 1/2
Our final answer: D: 
Answer:
I think your answer should be 5x and -5x
The slope of the graphed is 
.
Solution:
Two points represented in the line are (2, 4) and (–3, –4).
Here, 
To find the slope of the line:
Substitute the given points in the formula.
Slope of the line .
Hence the slope of the graphed is .
