Answer:
The expression is: ![\text{total thickness} = \text{cookie thickness} + \text{frosting thickness}](https://tex.z-dn.net/?f=%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Ctext%7Bcookie%20thickness%7D%20%2B%20%5Ctext%7Bfrosting%20thickness%7D)
The thickness of the cookie is:
cm
Step-by-step explanation:
The cookie is formed by two layers, the cookie and the frosting. So if we want to know the total thickness of the cookie and frosting we need to sum the thickness of each layer as shown below:
![\text{total thickness} = \text{cookie thickness} + \text{frosting thickness}\\\text{total thickness} = \frac{9}{10} + \frac{33}{100}\\\\\text{total thickness} = \frac{10*9 + 33}{100}\\\\\text{total thickness} = \frac{123}{100} \text{ cm}](https://tex.z-dn.net/?f=%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Ctext%7Bcookie%20thickness%7D%20%2B%20%5Ctext%7Bfrosting%20thickness%7D%5C%5C%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Cfrac%7B9%7D%7B10%7D%20%2B%20%5Cfrac%7B33%7D%7B100%7D%5C%5C%5C%5C%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Cfrac%7B10%2A9%20%2B%2033%7D%7B100%7D%5C%5C%5C%5C%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Cfrac%7B123%7D%7B100%7D%20%5Ctext%7B%20cm%7D)
The expression is: ![\text{total thickness} = \text{cookie thickness} + \text{frosting thickness}](https://tex.z-dn.net/?f=%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Ctext%7Bcookie%20thickness%7D%20%2B%20%5Ctext%7Bfrosting%20thickness%7D)
The thickness of the cookie is:
cm
Answer: D. The range stays the same, but the domain changes.
Step-by-step explanation: A function can be reflected over or across an axis. When the function is reflected in the y-axis, it means:
g(x) = f(-x)
i.e, the x-values are opposite to the original function.
In the image below, when we reflected the function across the y-axis, the new one will be drawn at the positive x-axis but still at the negative y-axis as shown in red at the second attachment.
<u>Domain</u> of a function is all the values x can assume. <u>Range</u> of a function is all the results the variable y assume.
According to the new graph, <u>y-values didn't change, so Range stays the same. However, x-values changed their signal. Therefore, domain changes.</u>
Answer: The answer is 40 minutes
Step-by-step explanation:
He only read 20 minutes last saturday so that means he needs to read 10 extra minutes so he can make up for the minutes he lost. Add 10 to 30 minutes and you get 40 minutes.
Answer:
y = 6x + 4
Step-by-step explanation:
We know the equation is linear. First, use two points to find the slope of the line.
m = (y₂ − y₁) / (x₂ − x₁)
m = (10 − 4) / (1 − 0)
m = 6
The y-intercept is 4. So the equation of the line is:
y = mx + b
y = 6x + 4
