Answer:
-15
Step-by-step explanation:
Answer:
a) 8 subsets
b) 32 subsets
Step-by-step explanation:
The total number of subset of a set is known as the power of the set
Power of a set is expressed as;
P = 2^n
n is the number of element in the set
a) For a set containing 3 elements
n = 3
Power of the set = 2³
Power of the set is 8
This means that the set contains 8 different subsets
b) Cardinality of a set is the total number of element in the set
If the cardinal number of a set is 5, this means that the set contains 5elements
Hence the power of the set will be;
P = 2^5
P = 32
Hence the total number of subset for set whose cardinal number is 5 is 32
Well first lets do the distributive property so the left side is already done 28, now the right side -4 (2x+7) when you do that you get -8x-28. So now we have 28=-8x-28. So now I would move the -28 to the left side and when you move stuff to the other side you change the sign so the sign will be positive 28+28 which is 56. Now you have 56=-8x. Now divide both side by -8 to have -7=x
Your Answer: x = -7
You set it equal to 0 then solve. you would move 4 over to the other side so you would have 1/5w=-4 then multiply -4 by the opposite of 1/5 which is 5. and you get
w= -20
Answer:
5,040 different arrangements.
Step-by-step explanation:
There are 7 different letters in PROBLEM so that would be factorial 7 :
7! = 7*6*5*4*3*2*1
= 5040,
