We first need to write the function in standard form.
y = -x^2 - 7x + 18
To find the axis of symmetry, we do -b/2a
The a and b are the coefficients of the x values.
So a would be -1 since -x is same as -1x
Follow that, b would be -7.
Then just plug the values in. - (-7)/2(-1) = -7/2
The axis of symmetry is -7/2
Answer:
Of those farms, 686 harvested 100 acres (0.40 km 2) or more, which accounted for over 196,000 of the total acres of trees harvested. That same year, there were only three U.S. Christmas tree farms with more than 10,000 acres (40 km 2) of cropland in production.
Explanation:
Each year, forests in North America grow significantly more wood than is harvested. In the U.S., average net annual increase in growing-stock trees on timberland is about 25 billion cubic feet.
The transition from desirable ethics to internal values to actual behavior is internalization of ethical issues and looking inward to ones values.
I believe the answer is d.
