3. now consider equations of the form x-a=sqrt (bx+c) where a, b, and c are all positive integers and b > 1
(a) create an equation of this form that has 7 as a solution and an extraneous solution. give the extraneous solution.
(b) what must be true about the value of bx+c to ensure that there is a real number solution to the equation? explain

Simonne used the following steps to simplify the given expression. 12 - 3(-2x + 4) step 1: 12 + (–3)·(–2x) + (–3)·(4) step 2: 12 + 6x + (–12) step 3: 12 + (–12) + 6x step 4: 0 + 6x step 5: 6x what property of real numbers was used to transition from step 3 to step 4? a. identity property of addition b. inverse property of addition c. associative property of addition d. commutative property of addition

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
