Answer:
a. No
b. Yes
c. No
Step-by-step explanation:
a. For BC and B'C to both be parallel to the y-axis when BC is parallel to the y-axis the figure must be rotated by a multiple of 180 degrees.
b. When you rotate a figure none of the angles in the figure change.
c. For D and D' to have the same coordinates the figure must be rotated by 360.
Answer:
If there is no context given, you cannot find out whether the graph is discrete or continuous.
You can multiply any number by both 9 and 27 to get an equivalent ratio. For example, you have 9:27. Multiply both of them by 2, and you get 18:54.
Answer: 2x -6
Step-by-step explanation:
a) 2 + 3 - 6 = 10 + 4 ⇒ -1 = 14
This is a false statement so it has NO SOLUTIONS, which means it is a CONTRADICTION
b) 17 + 5 = 23 + 4 - 6 ⇒ 25 = 21
This is a false statement so it has NO SOLUTIONS, which means it is a CONTRADICTION
c) 7 + 4 = 5 + 8 + 2 - 10 ⇒ 11 = 5
This is a false statement so it so it has NO SOLUTIONS, which means it is a CONTRADICTION
NOTE: When they make a true statement, then it has infinite solutions and is an Identity
