Question

ms. joseph is dropping marbles into a cylinder one at a time. she records the volume of what’s in the cylinder after each marble is dropped in. find the volume if there were 8 marbles. you’re trying to find the volume in the cylinder if there were 8 marbles. the number of marbles is represented by x, so start by substituting 8 for x in the equation. slope: 2 vertical intercept: 10 volume = initial volume + volume of marbles v = 10 + 2x v = 10 + 2·□

Explanation:

Step1: Substitute x=8 into equation

$v = 10 + 2 \cdot 8$

Step2: Calculate the product term

$2 \cdot 8 = 16$

Step3: Sum to find total volume

$v = 10 + 16$

Answer:

26 mL
