Question
Which of the following graphs could represent the relationship between the number of manuscripts, x, and the cost, y, of acquiring ISBNs for the manuscripts?
The correct answer is:
HINT : -Total minimum cost for acquiring ISBNs for manuscript = no. of manuscripts x minimum cost for acquiring ISBNs for each manuscript.
Explanation : Given the total no. of manuscripts are x and minimum cost for reviewing each is $125
Total minimum cost for acquiring ISBNs for manuscript = no. of manuscripts x minimum cost for acquiring ISBNs for each manuscript
∴y = 125 x is the equation of graph at x= 4 the graph y= 125 x 4 then y= 1000 like in option C.

An inconsistent system is a set of equations for which no solution exists.
One solution of the system is shown as x = y = z = 0. D must be zero for endless solutions (including non-zero ones). There are thus two possible possibilities for k, but there is only one non-zero answer, e.g.: The value of K can be 2 or 0.5.

4T - 8D = 12H
The given equation can be rewritten as
T = aD + bH , where a and b are constants. What is the value of a?
A constant is a fixed value that does not change. Symbols such as a, b, c, etc., often represent constants. These constant symbols are used in algebraic expressions and equations to represent fixed values that do not change as per the above question; a and b are constants.
