Answer:
The solution will be "x = 2 and x = -1".
Step-by-step explanation:
The given equation is:
⇒ 
On solving "
", we get
⇒ 
As we know, if the base are same then their powers will be added together.
⇒ 
...(equation 1)
⇒ 
...(equation 2)
From equation 1, we get
⇒ 
⇒ 
From equation 2, we get
⇒ 
⇒ 
So that the correct answer will be "x = 2" and "x = -1".
Answer:
Correlation
Step-by-step explanation:
- This can be explained if we consider the case of correlation as in correlation this condition can arrive where a statement should be satisfied to be true when does not in or make it true itself.
- Correlation is indicative of the degree to which there is a fluctuation in one more varying values together. The increase or decrease in the value is indicated by the positivity or negativity of the correlation respectively where the correlation itself does not make it true or is true in itself.
- sufficient and necessary conditions are fulfilled only when one value needs to be true or false for the other to be true or false respectively.
- Causality also known as causation is the effectiveness or potency in which one process or a cause, leads to the generation of of another process or an effect, where cause and effect are partially dependent on each other.
Answer:
10 persons
Step-by-step explanation:
Step one:
given data
We are told that they have a total of $275
also, they want to spend $5 on packing space
and a ticket cost $27 per person.
Step two:
let the number of persons be x
and let the total amount to be spent be y
hence the inequality is
y≤ 5+ 27x
now for y= $275, let us find x
Substitute into the inequality we have
275≤5+27x
275-5≤27x
270≤27x
Divide both sides by 27
x ≤ 270/27
x ≤ 10
Hence the number of persons should not be more than 10
