Step-by-step explanation:
X + 9= 7
get x by itself you -9 on both sides
X + 9 = 7
- 9. -9
X = -2

Just substract simple
Answer:
30 times
Step-by-step explanation:
It will take 6 spoonfuls to make one cup of flour, so you multiply 6 by 5 to get 30 spoonfuls.

Answer:
The correct answer is 10 for lowest average cost and the cost function is 0.2
+ 75x + 20.
Step-by-step explanation:
Average cost function is given by =
= C(x) = 0.2x +
+75.
For minimizing we need to find
C(x) = 0.
⇒
C(x) = 0.2 -
.
⇒
= 0.2
⇒
= 100.
⇒ x = ±10
⇒ x = 10 ; cost cannot be negative.
Second order derivative is positive which implies the average cost minimizes.
Original cost function is given by C(x) × x = 0.2
+ 75x + 20.
