Which statement about 'square root X - 5 minus square root X = 5'' is true? x = –3 is a true solution.
x = –3 is an extraneous solution.
x = 9 is a true solution.
x = 9 is an extraneous solution.

x=9 is an extraneous solution

Step-by-step explanation:

Given

Function is

for function to exist

Therefore, 9 satisfies the  above equation. It is it's extraneous solution.

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

x = 3 ± √(5+y)
