Solve for the variable y (move the x to the right of equal with changed sign)
M is the coefficient before the x and b is the known number
-3y = -12 - 6x
Since the y can't be negative, multiply every term for -1, therefore change their sign
3y = 6x + 12
To find y, divide both terms for 3
y = 2x+4
Therefore your answer is
y = 2x+4
Answer:
(-5, -8)
Step-by-step explanation:
150 minutes. (15,000/2)=7,500 which is 1/2 of the pool. If it fills 50 gallons per minute you’ll want to divide that by 50;(7,500/50) which equals 150
Domain: Set of all real numbersIf you want to express the domain in set-builder notation, then you'd write something like
which is fancy notation to basically say "x is any real number"
If you want to write the domain in interval notation, then you'd write
which is the interval from negative infinity to positive infinity. In other words, the entire real number line.
-----------------------------------------------------------------
The domain is the set of all real numbers because we don't have any restrictions to worry about. There are no division by zero errors. There are no cases where we have to worry about taking the square root of a negative number, or anything similar. Any number can replace x to generate an output for y.
Given:
.
Exponential regression model is
To find:
The exponential regression representing the population of Lazy Town as a function of time in years.
Solution:
Exponential regression model is
...(i)
We have, 
.
Substituting 
and 
in (i), we get.
Therefore, the exponential regression representing the population of Lazy Town as a function of time in years, is .
