! no links ! do these equations represent an exponential function?

a1. y= 12• x^12

a2. y= 7x+ 3

b1. what does the equation,
y= 130(0.45)^x represent?

exponential growth, decay, or linear?

What are “like terms”? why can we only add like terms?

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x

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.
