13) The sum of two numbers is 90. If one of the numbers is x, express the other number in terms of x. (Use the 1-2-3 Magic method to help you. Use a table!)

y = 90 - x

Step-by-step explanation:

x + y = 90

y = 90 - x

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
