Brazil is the most populous country in south america .in 2005 its population was about 186 million it was growing at a rate of 1.1%per year .Nigeria is th emost populous country in africa its population in 2005 was about 129 million it was growing at a rate of about 2.4%per year assuming that these growth rates continue , write function rules to predict the populations of these countrys for any number of years x in the future

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
