Step-by-step explanation: i know
The height scale is 75
<em><u>Solution:</u></em>
Given that you are trying to enlarge an image that is 4 centimeters tall and 10 centimeters wide onto a billboard that is 3 meters tall and 8 meters wide
We have to find the height scale
From given information,
Height of original image = 4 cm
Height of enlarged image = 3 meters
Both the units are different.
Let us convert 4 cm to meter
<em><u>Use the following conversion factor</u></em>
1 cm = 0.01 meter
4 cm = 4 x 0.01 meter = 0.04 meter
<em><u>What is the height scale?</u></em>
<em><u>Height scale is found by following:</u></em>
![height\ scale = \frac{height\ of\ enlarged\ image}{height\ of\ original\ image}](https://tex.z-dn.net/?f=height%5C%20scale%20%3D%20%5Cfrac%7Bheight%5C%20of%5C%20enlarged%5C%20image%7D%7Bheight%5C%20of%5C%20original%5C%20image%7D)
![height\ scale = \frac{3\ meter}{0.04\ meter}\\\\height scale = \frac{3}{0.04} = 75](https://tex.z-dn.net/?f=height%5C%20scale%20%3D%20%5Cfrac%7B3%5C%20meter%7D%7B0.04%5C%20meter%7D%5C%5C%5C%5Cheight%20scale%20%3D%20%5Cfrac%7B3%7D%7B0.04%7D%20%3D%2075)
Thus height scale is 75
Y= x + n
n = any possible real number like 3 and -8
