After the outbreak of a mysterious disease, the average wait time at a hospital increased by \( 70 \% \). Before the outbreak, the average wait time at the hospital was \( m \) minutes. Which of the following expressions could represent the average wait time at the hospital after the outbreak? Choose 2 answers: A \( m+70 \) (B) \( m+0.7 \) ( ) \( 1.7 m \)

d) \( 16 \cdot 4^{15}:\left(8^{2} \cdot 4^{5}\right)=8^{x} \)

Graph the parabola. \[ y=(x-1)^{2}+5 \] Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function button.

Solve the inequality. Express the solution set in set-builder notation and interval notation. Graph the solution set on a real number line. \[ 5(x-6)>4(x-6)+x \]
