Determine whether y varies directly with x. if so, find the constant of variation.
y=12x

Which function has the domain x> -11?

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
