2. Using the substitution method Zoe is solving the following system of equations algebraically:
y + 5x = -2
4x - 7y=-14
Which equivalent equation could Zoe use?
(1) 4(-5x - 2) + 5x =-14
(3) 4x - 7(- 5x – 2)=-14
(2) 4(5x – 2) + 5x =-14
(4) 4x – 7(5x – 2)=-21

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.

The value of the expression 16-^3/4 8 1/8 -6 6 1/40 1/64

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
