Answer:
B
Step-by-step explanation:
Using the cofunction identity
sin x = cos(90 - x)
Given
sin(3x + 19) = cos(5x - 25), then
3x + 19 = 90 - (5x - 25)
3x + 19 = 90 - 5x + 25
3x + 19 = 115 - 5x ( add 5x to both sides )
8x + 19 = 115 ( subtract 19 from both sides )
8x = 96 ( divide both sides by 8 )
x = 12 → B

Answer: These are all the answers written in Slope- Intercept Form
1. y = -1/5x + 1
2. y = -3/2x + 2
3. y = -2x +4
4. y = 2x - 3
5. y = 2x - 4
6. y = -3/4x + 1
7. y = 9/4x + 4
8. y = 2/5x - 2
9. y = -3/5x -5
