Question

Show that m = 2 is the root of the equation 9m – 4 = 14.

hintHint:

root of equation is value of m at which the equation becomes 0 find value of the m which satisfies the given equation.

The correct answer is: m = 2


    Ans :- m = 2 is root of equation 9m- 4 = 14
    Explanation :-
    Let F(m) = 9m - 4 - 14
    We know that m=2 is a  root if only if  F(2) = 0
    F(2) = 9(2) - 4 - 14 = 18 - 18 = 0
     therefore m equals 2 text  is the root of the equation  end text F left parenthesis m right parenthesis

    In the xy-plane, the point (2, 6) lies on the graph of y equals k over x   where k is a constant. Which of the following points must also lie on the graph?

    Note:
    Whenever there is an unknown constant in the given equation, we must always try to find the value of that constant first with the help of the given conditions. Another way to solve this question is; observe that the equation can be written as x y = k , that is, the product of the x co-ordinate and y co-ordinate always remains a constant. As the point (2, 6) satisfies it, we get that constant to be 12. So we check for which of the points in the options, the product of x co-ordinate and y co-ordinate is 12.
