Question

read the following description of a relationship:

an engineer is constructing a newtons pendulum using a frame that weighs 19 kilograms and steel balls that weigh 9 kilograms each.

let b represent the number of steel balls used and w represent the total weight of the pendulum.

complete the table using the function w = 9b + 19.

bw
2
4
6
891

Explanation:

Step1: Substitute \( b = 2 \) into \( w=9b + 19 \)

\( w=9\times2+19=18 + 19=37 \)

Step2: Substitute \( b = 4 \) into \( w=9b + 19 \)

\( w=9\times4+19=36+19 = 55 \)

Step3: Substitute \( b = 6 \) into \( w=9b + 19 \)

\( w=9\times6+19=54+19=73 \)

Answer:

When \( b = 2 \), \( w = 37 \); when \( b = 4 \), \( w = 55 \); when \( b = 6 \), \( w = 73 \)
