Emesto tried to determine the solution for the system of
equations using substitution his work is shown below.
in which step did ernesto make the first error?
xy=7
step 1
step 2
step 3
step 4
3x - 2y = 8
step 1 x=y+7
step 2: 3y + 7) - 2y = 8
step 3: 3y + 7 - 2y = 8
step 4y+ 7 = 8
step 5: y = 1

Which function is odd check all that apply a. y=sin x b. y=csc x c. y=cot x d. y=sec x

Need on this geometry question. explain how you did it.

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.
