The variables x and y vary directly. use the values to find the constant of proportionality,
. then write an equation that relates.
. write any fractions in simplest form.
y=45; x=40

k=?

y=?

direct variation equation: y=kx

Solve the equation by completing the square. x^2+2x=17

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
