Answer:
Brand A= 0.17 per pencil Brand B= 0.14 per pencil
Step-by-step explanation:
To find the price of each pencil, you divide the price by the number of pencils and then round to the nearest hundredth.
This seems like a lot more work than it is, but here we go
Simplifying<span>8 + -2y = 3y + -2
Reorder the terms:
8 + -2y = -2 + 3y
Solving
8 + -2y = -2 + 3y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3y' to each side of the equation.
8 + -2y + -3y = -2 + 3y + -3y
Combine like terms: -2y + -3y = -5y
8 + -5y = -2 + 3y + -3y
Combine like terms: 3y + -3y = 0
8 + -5y = -2 + 0
8 + -5y = -2
Add '-8' to each side of the equation.
8 + -8 + -5y = -2 + -8
Combine like terms: 8 + -8 = 0
0 + -5y = -2 + -8
-5y = -2 + -8
Combine like terms: -2 + -8 = -10
-5y = -10
Divide each side by '-5'.
y = 2
Simplifying
y = 2</span>
Answer:
f(-3)=3
Step-by-step explanation:
Plug in -3 for x.
f(-3)=-4(-3)-8
f(-3)=12-8
f(-3)=3
Hope this helps!
If not, I am sorry.
By taking a common factor, we will see that the equivalent expression is:
![12*\sqrt[3]{6c}](https://tex.z-dn.net/?f=12%2A%5Csqrt%5B3%5D%7B6c%7D)
<h3>
How to find the equivalent expression?</h3>
Here we start with the expression:
![5*\sqrt[3]{6c} + 7*\sqrt[3]{6c}](https://tex.z-dn.net/?f=5%2A%5Csqrt%5B3%5D%7B6c%7D%20%2B%207%2A%5Csqrt%5B3%5D%7B6c%7D)
Notice that if we define:
![\sqrt[3]{6c} = u](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6c%7D%20%3D%20u)
We can rewrite our expression as:
Now we can take the common factor u to write:
Now if we replace u y the cubic root, we will get:
So the correct option is the third one.
