Answer:
x nth term =6–3(n-1)
Step-by-step explanation:
Since they start at 6 its X nth term n=6- but since the since one is 6 its 3(n-1) so x nth term=6-3(n-1)
Answer:
y = 3x + 5
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define variables</u>
Slope <em>m</em> = 3
y-intercept <em>b</em> = 5
<u>Step 2: Write linear equation</u>
y = 3x + 5
Answer: A. c = 3d
I'm gonna go with c = 3d
Step-by-step explanation: c = 3d
After looking at the table I believe the equation would be c=3d. I came to this conclusion because (6)=3(2); (9)=3(3); (15)=3(5); 18=3(6). I really hope this helps!:)

Answer:
Step-by-step explanation:
Days Cost
2 6
3 9
5 15
6 18
Now to find equation that models the given data we will use two point slope form.
Formula:
Substitute the values in the formula
where y denotes the number of days and x denotes the cost
Let us suppose d denotes the number of days and c denotes the cost
So, equation becomes:
Hence an equation models the data in the table is
So, option A is true.
Answer:
Step-by-step explanation:
Deal #1: One pizza= $8.99
Deal #2: One pizza= $6.00
Deal #1: Two pizzas= $13.99
Deal #2: Two pizzas= $12.00
Deal #1: Three pizzas= $18.99
Deal #2: Three pizzas= $18.00
Deal #1: Four pizzas= $23.99
Deal #2: Four pizzas= $24.00
Therefore, after FOUR pizzas, deal #1 becomes a better deal.
