Question

y = 50 + 2x y = 40 + 2x Which statement about the pair of equations is true? A) The pair has no solutions because the equations are dependent. B) The pair has no solutions because the equations are not consistent. C) The pair has an infinite number of solutions because the equations are dependent. D) The pair has an infinite number of solutions because the equations are independent.

Answer 1

The pair has no solutions because the equations are not consistent.

Subtracting the second equation from the first gives 0 = 10, an obviously false result.

So the equations are not consistent.

answer is B
