The product of the function is 2x^2+ 5x - 3
We are to find the product of the functions x + 3 and 2x -1
Taking the product:
f(x)g(x) = (x+3)(2x -1)
f(x)g(x) = x(2x) - x(1) + 3(2x) + 3(-1)
f(x)g(x) = 2x^2 - x + 6x - 3
f(x)g(x) = 2x^2+ 5x - 3
Hence the product of the function is 2x^2+ 5x - 3

0.4 is the first one
0.4 is also the second one
The points lie on a line. Such a pattern is called a linear relationship because it represents a straight line relationship between the coordinates of the points. We can describe the relationship between x and y in words as follows: The y-coordinate is three times the x-coordinate.....hope this helps
so two fellows did all the carpeting in 10 days.
now, how long did "1" fellow work only? well, it worked for 10 days.
how long did the other fellow work for? well, it was working alongside the first one, and it was there for also 10 days.
so the two guys working together, really did 10+10 = 20 "days worth of work". So that the whole carpeting job can be done in 20 "days worth of work".
now if we want to finish it in 4 days, 20 ÷ 4 = 5.
so if we hire 5 guys, since each one will do 4 days worth, 5*4 = 20 <- the whole job.
For it to double its price the price has to be +100% more, and every year you get +2.4%, so you do:
100/2.4≈ 42 years or 41.66666667.. years.
