Answer:
check explanation for answer
Step-by-step explanation:
16 ÷ -8 = -2
- 2 \frac{2}{5} ÷ \frac{4}{5} = -3
3 \frac{3}{7} ÷ \frac{1}{7} = 3
-12.2 ÷ -6.1 = 2
Answer:
40% less
Step-by-step explanation:
12 lb is 8 lb less than 20 lb.
-8 lb
----------- = -0.4
20 lb
Multiplying this result by 100%, we get -40%.
This year's turkey was 40% less than last year's.

The answer choice which describes the function is; Choice B; neither symmetry about the y-axis nor has order 2 rotational symmetry about the origin.
<h3>What is rotational symmetry?</h3>
Rotational symmetry, otherwise termed radial symmetry, is the characteristic of a shape when it looks the same after some rotation by a partial turn. On this note, since the function represents a quartic graph, it follows that the function has neither symmetry about the y-axis nor has order 2 rotational symmetry about the origin.
Therefore, the function f(x) = −4x⁴ + 3x³ − 2x² − x + 5 is neither symmetry about the y-axis nor has order 2 rotational symmetry about the origin.

To solve any equation, we have to get the variables and the constants (numbers) on opposite sides of the equals sign.
First, we have to combine the like terms on the left side of the equation, resulting in
7a - 9 = 30
Then, because we want the constants on the right side of the equation, we have to +9 to cancel out the -9 on the left side.
7a=39
Next, the a has a coefficient of 7, which it is multiplied by. To undo multiplication, you have to divide. Therefore, we should divide both sides by 7.
a= 5 4/7 or 5.57142857143
In improper fraction form, a = 39/7, as this fraction cannot be simplified any farther.
