5x + 6y = 18 2x-3y-12
As a first step in solving the system shown, Yumiko multiplies both sides of the equation 2x-3y- 12 by 6.
By what factor should she multiply both sides of the other equation so she can add the equations and eliminate a variable?
What one-variable equation is she left with after adding?

Enter the number of complex zeros for the polynomial function f(x) = x 4+ 5x² +6

Which compound inequality could be represented by the graph?

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.
