Answer:
9 5/6 + 1 1/4 - 2 11/12 = 14
-37 7/8 - 20 -3 1/4 = 14 5/8
17/3 - 2 19/30 +5/2 = 10 4/5
23.1 + 1 7/10 - 18 1/5 = 66/10

Answer:
c. 
Step-by-step explanation:
the domain is the set of all possible inputs of a function, in other words, all the x-values that make up the function. in this function, the first x-value is 1, and the function is continuous all the way up to 6, so, the domain would be the answer in c.
Answer: A. 17 - 17 = 0
Step-by-step explanation:
A variable is a number
If the discriminant is a positive number, there will be 2 possible solutions. If you replace the entire section of b²-4ac with 16, you will see that the equation becomes; (-b+-√16)/2a --> leading to an answer with the + and another with the -.
If the discriminant is 0, there will be 1 possible solution, (again replace this into the discriminant value) (-b)/2a ---> this formula is used to also find the x coordinates of a vertex, fyi.
If the discriminant is a negative number, there will be no solution (since squareroot of a negative number is not possible)
Hope I helped :)
