What are the solutions to the equation x2 = 9? explain why is more than one solution to the equation.

ANSWER

The degree is two so it must have more than one solution.

EXPLANATION

The given equation is

Let us use the square root method to solve this equation.

Since the degree of x is two, the fundamental theorem of algebra says it must have 2 roots.

We take square root to obtain,

Split the plus or minus sign to obtain,

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
