What property was used to rewrite the polynomial expression
(x+5)+3(a+(6x)y) to (5+x)+3(a+(6x)y)

The parabola x = y² - 9 opens: a.)up b.)down c.) right d.)left

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
