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 when there are 3 marbles. you’re trying to find the volume in the cylinder when there are 3 marbles. the number of marbles is represented by x, so start by substituting 3 for x in the equation. slope: 2 vertical intercept: 10 volume = initial volume + volume of marbles v = 10 + 2x v = 10 + 2·\square

Explanation:

Step1: Substitute x=3 into equation

$v = 10 + 2 \cdot 3$

Step2: Calculate the product

$2 \cdot 3 = 6$

Step3: Sum the values

$v = 10 + 6$

Answer:

16 mL
