In exercises 1-3, find the sum.
1. (-6x² + 3x – 7) + (10x² + 4x - 2)
2. (10x4 + 3x2 – 5x + 4) + (7x5 – 5x* + 2x – 9)
3. (5x² + 3x² - 6x – 10) + (2x² – 7 x² + 6x + 1)

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

step-by-step explanation:

tangent z: 4/3

cosine y: 4/5

cotangent y: 4/3
