9. An ice manufacturing machine requires 10 minutes to warm up before the production of ice begins. The weight, in tonnes, of ice produced varies directly as the number of hours of production. Given that 20 tonnes of ice are produced when the machine is run for half an hour, find the weight of ice manufactured when the machine is run for \( 1 \frac{3}{4} \) hours.

Solve: \( \frac{16^{x-1}}{4}=64 \)

A furniture company plans to have 19 employees at its corporate headquarters and 8 employees at each store it opens. Let \( s \) represent the number of stores and \( m \) represent the total number of employees. \( m= \) the function \( m=8 s+19 \) to find the value of \( m \) when \( s=2 \).

[2. Graphs and Functions What is the slope of the line with the equation \( -3 x+4 y=8 \) ? Hint: Use the formula sheet to determine the formula(s) needed to solve the problem. A -3

Read the following description of a relationship: \[ \begin{array}{l}\text { A furniture company plans to have } 19 \text { employees at its corporate headquarters } \\ \text { and } 8 \text { employees at each store it opens. } \\ \text { Let } s \text { represent the number of stores and } m \text { represent the total number of } \\ \text { employees. }\end{array} \] Use the function \( m=8 s+19 \) to find the value of \( m \) when \( s=2 \). \( m=\square \)

Read the following description of a relationship: Tori uses 12 tomatoes to make each bowl of salad. Let \( s \) represent the number of bowls of salad and \( t \) represent the total number of tomatoes she uses. Use the function \( t=12 s \) to find the value of \( t \) when \( s=7 \).
