You're answer should be non of them if my math is right, but it usually is!
hope this helped!!! ;)
Answer:
Step-by-step explanation:
f(x) = x⁴ - 9x³ - 8x² - 9x - 2
f(-3) = (-3)⁴ -9*(-3)³ - 8*(-3)² - 9*(-3) - 2
= 81 - 9*(-27) - 8*9 + 27 -2
= 81 + 243 - 72 + 27 - 2
= 277

Answer:
The total number of units produced is 6 .
Step-by-step explanation:
Given as :
The earning of worker at the factory = $ 12 per hour + $ 2.50 each unit per hour
The total earning of worker per hour = $ 27
Let The total number of unit produced = x
According to question
The wage worker earn per hour + earning × per unit produced that hour = Total earning of worker per hour
Or, $ 12 per hour + $ 2.50 each unit per hour × x = $ 27
Or, $ 2.50 each unit per hour × x = $ 27 - $ 12
Or, $ 2.50 each unit per hour × x = $ 15
∴ x = 
Or, x = 6
Hence The total number of units produced is 6 . Answer
