A parent function is normally not streched or anything or shhifted
y=kx or
y=x^a or
y=a^x are exapmles
y=x is y=1x
y=2x^3 is not it because the parent would be y=x^3
y=1/x is y=x^-1
y=2^x is y=2^x
answer is 2x^3 is not a parent function
Answer:
$18
Step-by-step explanation:
20% of 30 is 6.
$18 is half of the total
The ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
<h3>What is wavelength?</h3>
The wavelength is the distance between two successive troughs or crests. The highest point on the wave is the crest, while the lowest point is the trough.
We have two notes
Number of cycle for blue = 8
Number of cycle for red = 4
Ratio = 8:4 = 2:1
Or
2 to 1
Thus, the ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.

Answer:
x=42
Step-by-step explanation:
<em>Add by 26 from both sides of equation.</em>
<em>6x-26+26=58+4x+26</em>
<em>Simplify.</em>
<em>6x=4x+84</em>
<em>Subtract by 4x from both sides of equation.</em>
<em>6x-4x=4x+84-4x</em>
<em>Simplify.</em>
<em>2x=84</em>
<em>Divide by 2 from both sides of equation.</em>
<em>2x/2=84/2</em>
<em>Simplify, to find the answer.</em>
<em>84/2=42</em>
<em>x=42 is the correct answer.</em>
<em>I hope this helps you, and have a wonderful day! </em>
