Answer:
The answer would be division (B)
Step-by-step explanation:
4x equals the total amount
x equals the cost of one item
Therefore you'd divide total cost by 4 and that would find the cost of one item
Answer:
2
Step-by-step explanation:
Use order of operations PEMDAS
3^2 = 9 * 2 = 18
20-18= 2
Answer:
y=-2x+15
Step-by-step explanation:
So first we can write it in point slope form.
That is y-y1=m(x-x1)
y1 is the y coordinate
m is the lope
x1 is the x coordinate
This means that the equation is:
y-7=-2(x-4)
We can then convert it to slope intercept form which is
y=mx+b
so
y-7=-2x+8
y=-2x+15
Answer:
The sum of the first 880 terms in the sequence is 2,273,920.
Step-by-step explanation:
Arithmetic sequence:
The difference between consecutive terms is always the same, called common difference, and the nth term is given by:

In which d is the common difference.
Sum of the first n terms:
The sum of the first n terms of an arithmetic sequence is given by:

ai = ai-1 + 6
This means that 
In this question:
Sum of the first 800 terms, so 
First term is -53, so 
The 880th term is:

Sum

The sum of the first 880 terms in the sequence is 2,273,920.
