The square of 9 less than a number is 3 less than the number, what is the number?

78

Step-by-step explanation:

The square of 9 is 9^2 which implies 9 × 9 = 81

Let the unknown number be represented by X. Thus,

9^2 - x = 3

81 - x = 3

Add x to both sides

81 - x + x = 3 + x

81 = 3 + x

Subtract 3 from both sides

81 - 3 = 3 - 3 + x

78 = x

x = 78

Check

81 - x = 3

Since x = 78

81 - 78 = 3

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

he sells x mount because thats eqivilqant to the maz and then divided into quarters
