[Answered] If [tex]$TU = 2x + 1$[/tex], [tex]$UV = 15$[/tex], and [tex]$TV = 5x - 20$[/tex], what is [tex]$TV$[/tex]?

[Answered] A cave system inside a mountain has caves at different elevations above and below sea level. One cave has an elevation of [tex]$-4 \frac{1}{4}$[/tex] meters. How can you use a vertical number line to determine whether the elevation of a second cave is greater than or less than [tex]$-4 \frac{1}{4}$[/tex] meters?

[Answered] Evaluate the following. If [tex]$h(x)=(x+3)(2 x-4)$[/tex], what is [tex]$h(-9)$[/tex]?

[Answered] $\begin{array}{l}\frac{2}{5} x-4 y=10 \\ \frac{2}{5} x-4(60)=10 \\ \frac{2}{5} x-240=10 \\ \frac{2}{5} x-240+240=10+240 \\ \frac{5}{2}\left[\frac{2}{5} x\right]=\frac{5}{2}[250] \\ x=265\end{array}$ What error did Malik make first when solving the equation $\frac{2}{5} x-4 y=10$? A. Malik did not multiply $\frac{5}{2}[250]$ correctly. B. Malik added 240 to each side of the equation. C. Malik did not multiply $\frac{5}{2}\left|\frac{2}{5} x\right|$ correctly. D. Malik substituted 60 for $y$ instead of $x$.

[Answered] A circle is centered at $(7,8)$ and has a radius of 11. Which of the following is the equation for this circle? $(x-7)^2+(y-8)^2=121$ $(x-7)^2+(y-8)^2=11$ $(x+7)^2+(y+8)^2=121$ $(x+7)^2+(y+8)^2=11

[Answered] On a winter evening at sundown, a Kansas City news station reports that the temperature is [tex]$-2^{\circ} F$[/tex] and will drop by [tex]$2^{\circ} F$[/tex] per hour until sunrise. At the same time, a Chicago news station reports that the temperature is [tex]$6^{\circ} F$[/tex] and will drop by [tex]$4^{\circ} F$[/tex] per hour. Which equation can you use to find [tex]$h$[/tex], the number of hours it will take the cities to reach the same temperature? [tex]\begin{array}{l} 2 h-2=6 h-4 \\ -2-2 h=6-4 h \end{array}[/tex] How long will it take for the cities to reach the same temperature? Simplify any fractions.
