Simply 9+1/2(7n-26)-8n
kakasveta [241]
Hi there!

9 + 1/2 (7n - 26) - 8n
= 9 + 7n*1/2 - 26*1/2 - 8n
= 9 + 3.5n - 13 - 8n
= 9 - 13 + 3.5n - 8n
= -4 + 11.5n

Hope this helps!

Four students were discussing how to find the unit rate for a proportional relationship. Which method is valid? “Look at the gra
AlladinOne [14]

The correct answer is: [A]: " Look at the graph of the relationship.  Find the y-value of the point that corresponds to x = 1 . That value is the unit rate."

<h3>What is  y-value?</h3>

The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). Also called "Ordinate".

Here, The "y-axis" is located on the "vertical axis" that represents the "dependent variable" (or, at times, the "control value") that cannot be "manipulated" / controlled/ or "selected" / since it represents the "y-value" of the corresponding coordinate to which the "x-value" happens to corresponds to at the given value for "x" .

Thus, the correct answer is: [A]: " Look at the graph of the relationship.  Find the y-value of the point that corresponds to x = 1 . That value is the unit rate."
