The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! so im pretty sure its 20
Answer:
two solutions
Step-by-step explanation: it cant be no solution because no solution will be a vertical line it can be one solution becuase y=x is a solution and so is y=4
Yes your answers are correct :)
Step by step review:
First line has product of 5 and (x+2) so product property is good.
2nd line has division so quotient property is good.
3rd line has equal log with base 2 so equality property is good.
4th line has multiplication so that is also good
5th line has distribution of 5 and 7 so distributive property is good.
Your answer is correct.
Answer:
The probability that on any given day the water supply is inadequate 
Step-by-step explanation:
Given
α = 2 and β = 3
As per Gamma distribution Function
Expanding the function and putting the given values, we get -
