Unit 2: Logic & Proof Homework 6: Algebraic Proof Directions: Name the property of equality that justifies each statement.

1. If a = 2b then a - c = 2b - c

2. x = x

3. 3(p - 7) = 3p - 21

4. If - 7k = - 42 , then k = 6

5. If m + n = 15 and n = 2 , then m + 2 = 15

6. If x/4 = - 5 , x = - 20

7. If w ^ 2 = 2x and 2x = y , then w ^ 2 = y

8. If c - 9 = - 1 then c = 8

9. If n = - 3 , then - 3 = n

If g(x) = x+1/ x-2 and h (x) =4 - x , what is the value of ( g*h) (-3)?

Which is the graph of the function y=2(4)^x

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.
