Answer:
Roots (It has a solution)
Step-by-step explanation:
One method to find out whether or not this equation has a solution or not is to try to solve for x..

As we could find a solution, it has a root.
Answer:
17: A,C,B 18: C,A,B 19: A,C,B 20:A,C,B
Step-by-step explanation:
Slope(rate of change) can be found by dividing the change in y over the change in x. For example, #17 table, the change in y is (1-0)=1 and the change in x is (6-3)=3. Now, divide the to to get 1/3. Once you have all the rates of change you can list them in order.
