Use the following information. Most meat thermometers are accurate to within plus or minus \(2^{\circ} \mathrm{F}\). Ham needs to reach an internal temperature of \(160^{\circ} \mathrm{F}\) to be fully cooked. To what temperature reading should you cook a ham to ensure that the minimum temperature is reached? Explain.

Evaluate each expression if \(x=4, y=-2,\) and \(z=3.5\) \(\frac{y^{3}+2 x z}{x^{2}-z}\)

Solve each inequality. Then graph the solution set on a number line. \(4 y+7>31\)

Solve each equation. Check your solution. $$ y+14=-7 $$

Identify the additive inverse and multiplicative inverse for each number. $$ -8 $$

Solve each inequality. Then graph the solution set on a number line. \(n \leq \frac{n-4}{5}\)

Use the following information. Simple interest is calculated using the formula \(I=p r t,\) where \(p\) represents the principal in dollars, \(r\) represents the annual interest rate, and \(t\) represents the time in years. Find the simple interest I given each set of values. \(p=\$ 1800, r=6 \%, t=4\) years

Solve each equation. Check your solutions. \(|x+4|=17\)

Solve each inequality. Graph the solution set on a number line. $$ |h| < 3 $$

Use the following information. Simple interest is calculated using the formula \(I=p r t,\) where \(p\) represents the principal in dollars, \(r\) represents the annual interest rate, and \(t\) represents the time in years. Find the simple interest I given each set of values. \(p=\$ 31,000, r=2 \frac{1}{2} \%, t=18\) months
