The first thing you would do is switch the x and y (B).
For example, to find the inverse of y = 2x + 8:
1. Swap x and y
x = 2y + 8
2. Solve for y (set the equation equal to it):
x - 8 = 2y
y = (x - 8) ÷ 2
= 1/2x - 4
For example, to find the inverse of y = 2x + 8:
1. Swap x and y
x = 2y + 8
2. Solve for y (set the equation equal to it):
x - 8 = 2y
y = (x - 8) ÷ 2
Answer:
Step-by-step explanation:
Angles <em>B</em><em> </em>and<em> </em><em>C</em><em> </em>form a straight angle, so you set both expressions equal to 180°:
180° = (2x + 15)° + x°
180° = 15° + [3x]°
- 15° - 15°
