100 Solve for x: M is the midpoint of AB. AM = 4x + 19 BM = 2x + 13
100 What is ? Question: M is the midpoint of AB. AM = 4x + 19 BM = 2x + 13
200 A, B and C are collinear and B lies between A and C. If AB = 2x + 4, BC = 12, AC = 4x – 6, then find AC.
A, B and C are collinear and B lies between A and C. If AB = 2x + 4, BC = 12, AC = 4x – 6, then find AC. 200 First, 2x + 4 + 12 = 4x – 6 x = 11 Therefore, AC = 38
300 O is the midpoint of FX. If FO = 3x + 6 and FX = 66, then solve for x.
300 3x + 6 = ½ 66 x = 9
400 C is the midpoint of AE. If A is located at (7, 1) and C is located at (2, –3), then find the coordinates of E.
C is the midpoint of AE. If A is located at (7, 1) and C is located at (2, –3), then find the coordinates of E. C is in the middle!!! From A to C, we go left 5 and down 4, so if we do it again, we end up at E = (–3, –7) 400
500 Find the midpoint of AB if A is located at (a + c, d – e) and B is located at (g – h, s + t).
Find the midpoint of AB if A is located at (a + c, d – e) and B is located at (g – h, s + t). 500
100 Ray OX lies in the interior of BOD. If mBOX = 2x + 9, mDOX = 3x – 2, and mBOD = 72, find mBOX.
Ray OX lies in the interior of BOD. If mBOX = 2x + 9, mDOX = 3x – 2, and mBOD = 72, find mBOX. 100 2x + 9 + 3x – 2 = 72 x = 13 mBOX = 35
200 A and B are complementary. If mA = 2x + 4 and mB = 7x - 22, find mB.
A and B are complementary. If mA = 2x + 4 and mB = 7x - 22, find mB. 200 2x + 4 + 7x – 22 = 90 x = 12 mB = 62
300 A and B are a linear pair. If mA = 70 – 2x and mB = 8x – 10, find mB.
A and B are a linear pair. If mA = 70 – 2x and mB = 8x – 10, find mB. 300 70 – 2x + 8x – 10 = 180 6x + 60 = 180 x = 20 mB = 150
400 Ray UP bisects TUX. If mTUP = 3x + 4 and mTUX = 104, solve for x.
Ray UP bisects TUX. If mTUP = 3x + 4 and mTUX = 104, solve for x. 400 3x + 4 = ½ 104 3x = 48 x = 16
500 Based on the following, find mDXC. B (5x – 40)° A C X (2x + 2)° D
500 5x – 40 = 2x + 2 (vertical angles) x = 14 Plugging in… mAXD = 30 THEREFORE, mDXC = 180 – 30 = 150 B (5x – 40)° A C X (2x + 2)° D

Point A is at (3, 4) and Point B is at (–1, –5). Find the new location of each point when they are translated 2 units up and 4 units left. 200 Be careful…read the question… (up 2 = y + 2, left 4 = x – 4) A’ is at (–1, 6) B’ is at (–5, –3)
300 When A (–5, 2) and B (–3, 6) are reflected about the y-axis, the new coordinates of B’ are:

400 Point A (6, –4) is first reflected about the origin, then reflected about the x-axis. The new coordinates of A’ are:
Point A (6, –4) is first reflected about the origin, then reflected about the x-axis. The new coordinates of A’ are: It first moves to (–6, 4), then it moves to (–6, –4). 400

500 A (–7, 2) is rotated 90 counterclockwise. Find the location of A’.
500 The x-dimension and y-dimension switch every 90 and one sign changes. Since we rotated “left”, both the x and y became negative. (–2, –7)
100 Define inductive and deductive reasoning. Identify key phrases to help identify each type.
100 Inductive = INFERRING GENERAL TRUTHS based upon SPECIFIC EXAMPLES or a PATTERN Deductive = USING LOGIC to DRAW CONCLUSIONS based upon ACCEPTED STATEMENTS.

“If Noah studies well, then Noah earns 100% on the test.” 200 Converse: (Switch the If and then parts) “If Noah earns 100% on the test, then Noah studied well.” Contrapositive (switch AND negate it) “If Noah does NOT earn 100% on the test, then Noah did NOT study well.”
