For this case we can write the system of equations as two equations with two unknowns. We then define the following unknowns: incognitas: x and y. We write the system of equations: y = x2 + 3x + 1 y = 2x2 + 2x + 3 Answer: y = x2 + 3x + 1 y = 2x2 + 2x + 3
The answer would be D. y=75x+300 because if you multiply 75 and 20 you would get 1500 and subtract 1800 for how much was paid and 1500 for the result of multiplying 75 and 20 Answer is D. y=75x+300
