Question

the graph shows the relationship between the number of marbles and the volume in a new cylinder. find the volume if there were 9 marbles. multiply 4 times 9 to find the volume of the marbles, or how much the volume in the cylinder would increase by if 9 marbles were added. slope: 4 vertical intercept: 6 volume = initial volume + volume of marbles v = 6 + 4x v = 6 + 4·9 v = 6 + \square

Explanation:

Step1: Calculate volume of 9 marbles

$4 \times 9 = 36$

Step2: Substitute into volume formula

$v = 6 + 36$

Step3: Compute total volume

$v = 6 + 36 = 42$

Answer:

First, the missing value from $4 \cdot 9$ is $\boldsymbol{36}$, and the total volume with 9 marbles is $\boldsymbol{42}$ mL.
