What would need to be added to both sides in order to complete the square in the following equation? x² — 18x + 9 = 17?

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

step-by-step explanation:

it's possible to build a triangle with side lengths of 3, 3, and 9.- true ( b.)

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
