Answer:
1. Equal
2. Not equal.
Step-by-step explanation:
1. -2 * -0.16 = -0.32
0.16 * (-2) = -0.32 EQUAL
2. 0.4 / (-3) = - 0.1333...
-3 / 0.4 = -7.5 Not equal
Unit price means the cost per unit.
I'll provide an example.
If 4 bars of soap cost $2.35, find the unit price. Round to the nearest cent if necessary.
Remember that the unit price is the cost per unit which in this case is the cost per bar of soap. Since $2.35 is the cost for 4 bars of soap, to find the cost per bar of soap, we divide 4 into $2.35.
When we do this, we get an answer of 0.587 which rounds up to 59 cents.
Therefore, the unit price for soap is 59 cents.

Answer:
B. (1, 2)
Step-by-step explanation:
In a function, each value used in as an x-coordinate can be used only once.
Values already used as x-coordinates: -3, 8, 0, -5
The answer cannot have -3, 8, 0, or 5 as an x-coordinate.
The only choice without one of those four values as an x-coordinate is (1, 2).
Answer: B. (1, 2)

Regardless of the sign of

, we have

(never negative). But multiplying by -1 makes it negative.
On the other hand,

which can never be negative for real
