1. Explain whether this number is prime or composite: 12 2. Explain what makes it either prime or composite.

1.The number 12 is a composite number.

2. The numbers which are divided only by 1 and the number itself is a prime number. The rest of the numbers are composite. the number 12 has factors like 1,2,3,6 &12 so it is a composite number.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

answer: (3,11) is your answer.
