When Nicole left her house in the morning, her cell phone battery was partially charged. The charge remaining in Nicole's battery, as a percentage, can be modeled

by the equation B = -9t + 72, where t is the number of hours since Nicole left her

house. What is the slope of the equation and what is its interpretation in the context

of the problem?

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

Wrote and expression for the difference of p and 4

What is the slope of the line (-7,2) (4,6)
