Can you me with these? i need on how to solve these questions! urgent!

You can fill the choices into the equations for x and solve then to see if they are correct. For example, you could put -3 and 3/2 into x^2-12x+27=0
Which would make (-3)^2-12(3/2)+27=0.
From the picture I posted, you can see that 0=0, so the equation is correct

Aline graph should be used

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
