Answer:
B
Step-by-step explanation:
We are given that Expression One is:
And Expression Two is:
We are given that the value of Expression Two is 20,000 times greater than the value of Expression One. And we want to find the value of <em>y.</em> In other words:
We can divide both sides by four:
Recall that:
Therefore:
Divide both sides by 10ˣ:
Solve for <em>y: </em>
<em />
<em />
Our answer is B.
Answer:
Step-by-step explanation:
We can observe the figures are mirrored over y- axis.
<u>This is a reflection and the rule is:</u>

<u><em>The correct answer is: </em></u>4.2 inches.
<u><em>Explanation</em></u><span>
<u><em>: </em></u>We use the size of the largest dimension of the reproduction to find the scale factor. The largest dimension of the original drawing was 5 inches.
The largest dimension of the reproduction is 11 inches.
<u>To find the scale factor, divide: </u>
</span></span>
<span><span>=2.1.
Since the scale factor is 2.1, to find the smallest dimension of the reproduction we <u>multiply the original by 2.1</u>:
2*2.1=4.2 inches.</span></span>
