N A HAB Generating Equations and Inequalities Target 1 Generate equations in two or more variables to represent situations involving relationships between quantities Target 2 Gonerate inoqualitios in two or more variablos to ropresent situations involving rolationships betwoen quantities 7. A hot air balloon at 4000 feet begins its descent. It descends at a rate of $200$ feet per minute. The function 6000 $f\left(x\right)=-200x+4000$ represents the height of the balloon as it descends. $5000$ a) How many minutes have passed if the balloon is feet) 4000 below $3000$ $teet$ Write as an inequality, solve, then ght Hei3000 graph the sollution on a number line. $2000$ $1000$ 10 15 Time (minutes) & Using the graph $Pro+iA=a$ $\left(3\right)ho$ many minutes have passed $1t1ca$ still has more than $2000fca1t0$ walk Write as an inequality, solve, then graph the solution on A number line 4000 3000 2000 1000 15 1ime runutes)

Practice $Norkshcet$ Solving Rational Equations and Inequalities Solve each equation. Check extraneous solutions for rational equations.
