Where x is years after 1999, the population is predicted to be ...
p(x) = 478,434*1.07^x
For x=11, this is
p(11) = 478,434*1.07^11 ≈ 1,007,033
The relation predicts the Las Vegas population in 2010 to be 1,007,033.
A first step in solving the equation 1/4 x + 1/2 = 3/4x will be answer A multipllied by 4 on both sides.
What is an equation?
The equation is actually a relationship between the numbers and the variables.The given equation is 1/4 x + 1/2 = 3/4x
Now the solution of the equation will be:-
1/4 x + 1/2 = 3/4x
By multiplying with 4 the equation will become:-
x+2=3x
3x-x=2
2x=2
x=1
Hence the solution of the given equation will be x=1
