Select the correct answer. Consider the following system of equations.

y − 10 = 7x
y = x2 + 4x

Determine which resulting quadratic equation would be a step in solving the given system of equations.

x2 + 3x + 10 = 0

x2 + 3x − 10 = 0

x2 − 3x + 10 = 0

x2 − 3x − 10 = 0

Apositive number a or the same number a increased by 50% and then decreased by 50% of the result?

Is this a polynomial function? i need to know asap
