Answer:
x=-1,-2
Step-by-step explanation:
Multiply the given equation with (x+1) on both sides. We'll get,
x+2/x=-3
or,x^2+2=-3x
or,x^2+3x+2=0
or,x^2+2x+x+2=0
or,x(x+2)+1(x+2)=0
or,(x+2)(x+1)=0
or,x=-2,-1
Substitute 22 for x
2(22)-5
44-5
39
Answer:
x = 12
Step-by-step explanation:
In order for these lines to be parallel:
5x = 4x + 12
x = 12
Hope this helps
Answer:
The commutive property used twice, once on each of the two multiplication
The commutive property is where you can be able to switch around the numbers to multiply the problem to get your solution.
Since we are trying to find the number of sequences can be made <em>without repetition</em>, we are going to use a combination.
The formula for combinations is:
is the total number of elements in the set
is the number of those elements you are desiring
Since there are 10 total digits, 
in this scenario. Since we are choosing 6 digits of the 10 for our sequence, 
in this scenario. Thus, we are trying to find 
. This can be found as shown:
There are 210 total combinations.
