[Answered] Use the drawing tool(s) to form the correct answers on the provided answer space. Beth is tracking how many miles she walks in a week. Currently, she has walked one mile and plans to walk at a brisk pace of five miles per hour for the rest of the week. Her brother Jonathan is also tracking the miles he walks in a week. He has already walked three miles and plans to walk at a slower pace of three and a half miles per hour for the rest of the week. The system of equations below represents the miles, [tex]y[/tex], walked by Beth and Jonathan in [tex]x[/tex] hours. [tex] \begin{array}{l} y=5 x+1 \ y=3 \frac{1}{2} x+3 \end{array} [/tex] Part A: Use the ray tool to graph the system of equations on the coordinate plane. Part B: Use the point tool to select an approximate amount of time Beth and Jonathan will each have to walk this week in order for them to have walked the same distance.

[Answered] At the annual art competition in Tiruvannamalai, there were 10 talented participants, out of which 6 were boys and 4 were girls. As the event reached its climax, the chief Kavitha announced: "For the grand finale, we must select a group of 5. But remember, our jury would love to see at least two girls in the final round!" As the audience waited in anticipation, Pranav, last year's winner, turned to his friend, Gopal and whispered, "What's the probability that the randomly chosen group of 5 has at least two girls?" If Gopal calculated the correct answer, what answer did he find? Note: Round off your answer to 3 decimal places. For example, if the answer is 0.5 put 0.500, if the answer is 0.5447 then put 0.545 and if the answer is 0.7825 then put 0.783.

[Answered] Solve the equation $6 z+9 z=p z+v$ for $v$. $v=$

[Answered] Since slope is calculated using the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex], and line [tex]z+b[/tex], the slope of both lines is equivalent to ________. It is given that the lines are parallel, and we calculated that the slopes are the same. Therefore, parallel lines have the same slopes. [tex]\frac{z-v}{x-w}[/tex] [tex]\frac{x-w}{z-v}[/tex] [tex]\frac{v-z+b}{x-z+a}[/tex] [tex]\frac{w-x+a}{v-z+b}[/tex]

[Answered] Which values are within the range of the piecewise-defined function? [tex]f(x)=\left\{\begin{array}{ll} 2 x+2, & x\ \textless \ -3 \\ x, & x=-3 \\ -x-2, & x\ \textgreater \ -3 \\ \end{array}\right.[/tex] y=-6 y=-4 y=-3 y=0 y=1 y=3

[Answered] What number should be added to both sides of the equation to complete the square? [tex]x^2-6 x=5[/tex]

[Answered] Complete the following multiplication and division calculations involving fractions (show all the steps). [tex]$4.1 \cdot 1 \cdot \frac{4}{6} \div \frac{3}{12}$[/tex]
