Ashaunte was given the following set of data about 37 college women and invitations to join social organizations: 20 received invitations for alpha pi; 21 for beta zeta; 12 for gamma iota; 10 for alpha pi and beta zeta; 5 for beta zeta and gamma iota; 9 for alpha pi and gamma iota; and 5 received no invitations. she was asked to determine how many women were invited to join all three organizations and how many were invited to join alpha pi and beta zeta but not gamma iota. can you determine the numbers she needs?

answer: its the third option.

step-by-step explanation:

i just took the test.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely
