Answer:
-15.9%
Step-by-step explanation:
Opening stock = $8.18
Closing stock = $6.88
Loss = $1.30
Rate = - loss/opening stock × 100
= - 1.39/8.18 × 100
= - 15.9%
The answer would be (11) since that number is used to multiply the variable y.
Answer:
Function is decreasing on (-8,infinity)
Step-by-step explanation:
The given function is 
The first derivative is given by

For the function to be decreasing, we have

Divide both sides by -2. Since, we are dividing by a negative number hence, the inequality sign will change.

Subtract 8 to both sides

Therefore, the function is decreasing on (-8,infinity)
First option is correct.
