If 3x−y=12, what is the value of 8x2y?
D) The value cannot be determined from the information given.
y = 3x - 12 ...... but x, y can take on infinite values because this is a line
So...without any other info
8x2y could take on infinite values, as well
which can be rewritten
Since the numerator and denominator have a common base, this expression can be rewritten as 2(3x−y). In the question, it states that 3x−y=12, so one can substitute 12 for the exponent, 3x−y, which means that
I think is this right?
