Answer:
12 ≥ x - 7
Step-by-step Explanation:
When it says twelve is at least, it means that twelve is at least equal to something and it can also be greater. And when it says a number decreased by seven, it means a number, which is the variable x because it’s unknown, minus 7. All of this can be expressed as 12 ≥ x - 7, which is true because a number, which is x, minus 7, is the smallest “thing” that 12 can equal to.
I hope you understand and that this helps with your question! :)

Step-by-step explanation:
Given the zero x = a of f(x) then f(a) = 0
(5)
f(9) =9³ - 8(9)² - 2(9) - 63 = 729 - 648 - 18 - 63 = 0
Hence x = 9 is a zero of the polynomial
(6)
2
- 3(- 3)³ - 36(- 3)² - 37(- 3) - 26 = 162 + 81 - 324 + 111 - 26 = 4 ≠ 0
Hence x = - 3 is not a zero of the polynomial
