A proportional relationship between the number of pounds of oranges (x) and the price in dollars (y) can be graphed, and the ordered pair (6, 5) is on the graphed line. Part A: What is the price of 1 pound of oranges? Show your work. (8 points)
Part B: What does the ordered pair (12, 10) on the graph represent? Explain in words. (2 points)

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

step-by-step explanation:

compare

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
