Answer: n < -5 or n > 5
Step-by-step explanation: Solve for n
Answer: No. You reversed the domain and range
#2) B) x ≥ 0
#3) B) [0, ∞)
<u>Step-by-step explanation:</u>
#2 is asking about the domain, which is all of the x-values.
The graph appears to be touching the y-axis so it equals 0 and all other x-values are greater than zero. (0, 1), (1, 0), (2, -0.8), (3, -1.5), etc. All of the x-values are moving toward the right, which is positive infinity. --> x ≥ 0
#3 is asking for the range, which is all of the y-values.
The vertex is at (0, 0) and all other y-values are above zero (positive numbers), moving toward positive infinity. --> [0, ∞)
<h3>Solution:</h3>
<u>Given:</u>
<u>In the diagram given, we can tell that:</u>
- ∠A and ∠B are a linear pair.
- ∠B and ∠C are a linear pair.
<u>This means that:</u>
- ∠A + ∠B = 180°
- ∠B + ∠C = 180°
<u>Step-1: Find ∠B.</u>
- ∠A + ∠B = 180°
- => 50 + ∠B = 180°
- => ∠B = 180 - 50
- => ∠B = 130°
<u>Step-2: Find ∠C.</u>
- ∠A = ∠C (Vertically opposite angles
- => ∠C = 50°
