Answer:
(-∞,-4)
Step-by-step explanation:
1. Move like terms together
-4x + 18 ≤ - 2 -9x
Move -9x, the sign changes to a positive
-4x + 18 +9x ≤ -2
Move 18, the sign changes to a negative
-4x + 9x ≤ - 2 -18
2. Combine like terms
-4x+9x becomes 5x
-2-18 becomes -20
The new equation is 5x≤-20
3. Divide both sides by 5
5x÷5=x
-20÷5=-4
x≤-4
4. Write in interval notation
1. -18 +15x = 3(4x-6) + 3x
-18 + 15x = 12x - 18 + 3x
-18 + 3x = -18 + 3x
3x = 3x
x = All Real Numbers (because we don't know what x is since the equation is 3x = 3x, we can assume that it is all "real" numbers)
2. -10 + 5x = 5(x - 3) + 5
-10 + 5x = 5x - 15 + 5
-10 = -10
Answer Undefined (because the x coefficients canceled out, we don't know what x even is, so we can claim it as undefined.)
Pearl's Proof is incorrect.
The theorem is to proof ∠AKL≅ ∠FLK.
The real proof is as follows:
- Line AB ║ EF with transversal segment Gj
- Angle AKL is congruent to angle GKB . (Vertical Angles Theorem)
- Angle GKB is congruent to angle FLK (Corresponding Angles Theorem)
- angle AKL is congruent to angle FLK (Transitive Property)
Therefore, Tonya's Proof is definitely right and Pearl's Proof is definitely wrong.
The second proof of pearl was wrong. Angle AKL is congruent to angle GKB but they are not adjacent angles.

(f – g)(x) = 3x + 2 - (2x - 2)
(f – g)(x) = 3x + 2 - 2x + 2
(f – g)(x) = x + 4
