What number should be added to both sides of the equation to complete the square?x2 – 6x = 5

Answers

take 1/2 of -6 and square it
-6/2=-3
(-3)^2=9
9 should be added
x^2-6+9=5+9
(x-3)^2=14

9 should be added

To complete the square of the equation, the number to add to both sides is: 9.

How to Complete the Square of an Equation?

To complete the square of an equation, the number to add to both sides should be determined by squaring half of the term that has a variable without an exponent.

Given the equation, x² - 6x = 5:

To complete the square, square half of -6

1/2 of -6 = -3

Square of -3 = 9

Therefore, to complete the square of the equation, the number to add to both sides is: 9.

Jayne stopped to get gas before going on a road trip. The tank already had 4 gallons of gas in it. Which of the statements below best describes why the graph relating the total amount of gasoline in the tank, y, to the number of gallons that she added to it, x, will be continuous or discrete? A. The graph will be continuous because the amount of gas that she added to the tank does not need to be an integer amount. B. The graph will be continuous because we are not told a maximum value for the amount of gas. C. The graph will be discrete because there are already exactly 4 gallons of gas in the tank.

Answers

A. The graph will be continuous because the amount of gas that she added to the tank does not need to be an integer amount.
