If u need to get 20% of $34 u can find 10% which is 3.40 which means to get 20% you need to double it to 6.80 and that’s how much the tip was therefore if she had her total bill of $34+$6.80 tip that means the total is $40.80
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.

Answer:
so
slope is calculated this way:
let's calculate y init by:
3 = -3×2 + b
b = 9
so equation is:
y=-3x+9
X= -46 and y = -40 I worked it out I might be wrong
