Answer:
2
Step-by-step explanation:
10-2=8.
The general term is

(a sub n; n is a subscript)
The first term is a1
The second term is a2
The third term is a3
and so on...
The first term starts at n = 1. We replace the n in

with 1 to get

. A similar thing happens with n = 2 and onward
The domain is therefore the set {1, 2, 3, 4, 5, ...} which is the set of...
* Counting numbers
* Positive Whole numbers
* Natural numbers
Those are three ways to express the same set
We can also say

where n is an integer or whole number
A similar inequality would be

which is effectively the same as idea as the last inequality (n is also an integer or whole number).
Answer:
166.8 pounds.
Step-by-step explanation:
Let b be the number of batches baked and f be the total weight of flour.
We have been given that a cupcake factory has already used 22.8 pounds of flour today.
They are now making cupcakes that require 8 pounds per batch, so the weight of flour used in b batches will be 8b.
The equation representing the total weight of used flour is given as:
To find the total weight of flour used, when 18 batches are baked we will substitute b = 18 in our given equation.
Therefore, the total weight of flour used in baking 18 batches will be 166.8 pounds.
A) The intersection occurs at the same height 'y', so the y of each equation must be equal:
y=y implies <span>2−x = 8x+4. The solution is -2=9x, x = -2/9=2/3, and y = 20/9
(-2/9,20/9)

B)
X | Y1 | Y2
_____________
-3 5 -20
-2 4 -12
-1 3 -4
0 2 4
1 1 12
2 0 20
3 -1 28
C) I would draw each line with the values on the table. Where both lines cross is the intersection point. It should be (-2/9, 20/9)
