Answer:
4
Step-by-step explanation:
Answer:
125°
Step-by-step explanation:
ABC + CBD = 180
(Supplementary angles)
8x - 41 + 9x + 17 = 180
17x = 204
x = 12°
CBD = 9(12) + 17 = 125°
Answer:
y= -2x + 9
Step-by-step explanation:
I got 2x because you use rise over run. As you can see in the image, the slope goes up two and to the left one ( 2x). It's plus 9 because that where it intersects the 9 on the y-intercept. The slope is negative because the line is going down from left to right ( always read it from left to right).
I hope this helps. I'm not that great at explaining so....:)
