1) Winston needs at least 80 signatures from students in his school before 10 points he can run for class president. He has 23 signatures already. He and two
of his friends plan to get the remaining signatures during lunch. If each
person gets the same number of signatures, which inequality can
Winston use to determine the minimum number of signatures each
person should get so he can run for class president?
3x + 80 23
3x + 80 3 23
Option 1
Option 2
3x + 23 80
3x + 23 < 80

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x
