Answer:
a. Negative discriminant: above
b. Positive discriminant: below
c. Discriminant is zero: on
Step-by-step explanation:
If the discriminant is negative, then there are no real zeros. We have an upward-facing parabola, then the vertex is located above the x-axis
If the discriminant is positive, then there are two different real zeros. We have an upward-facing parabola, then the vertex is located below the x-axis
If the discriminant is zero, then there is one zero. We have an upward-facing parabola, then the vertex is located on the x-axis
Answer:
B. Combine like terms
Step-by-step explanation:
Inside the parenthesis, they combined -2 and 6 to get a total of 4x
Answer:
3.375 pounds.
Step-by-step explanation:
Total number of pounds of pecans =
2 1/2 pounds of pecans + 4 3/8 pounds + 3.25 pounds
= (6.875 + 3.25) pounds
= 10.125 pounds.
The total number of person = 3 person.
Therefore, the number of pounds each person would shell =
10.125 pounds/3
= 3.375 pounds
