13.2 Addition and Subtraction Inequalities Solve each inequality. Graph the solution. 4. C - 28 -32 5. + 17 20 6. Today's high temperature of 80'F is at least 16' warmer than yesterday's high temperature. What was yesterday's high temperature? 13.3.13.4 Multiplication and Division Inequalities Solve each inequality. Graph the solution. 7. 7 S 35 9 10 9.259 2 150 10.

Answer 1

The inequality is

$80\ge x+16$

Where x is yesterday's temperature.

$\begin{gathered} 80\ge x+16 \\ 80-16\ge x \\ 64\ge x \\ x\leq64 \end{gathered}$

Hence, yesterday's high temperature is at most 64 degres F
