Answer:
rise, run
Step-by-step explanation:
When finding the slope of a line using a slope triangle, the RISE length is divided by the RUN length. (I think. Sometimes the "divided by" makes me confused about which is on top, but I'm pretty sure this is right.)
Answer:
the answer is inspection
Step-by-step explanation:
Center is (-6,7) and radius is 9. A circle with a center at (h,k) and a radius of r has the equation (x-h)^2 + (y-k)^2=r^2 so h= -6 k= 7 r is 9 you just work back wards, what two numbers multiplied gives you 81? Well 9
Answer:
d. 
Step-by-step explanation:
![\displaystyle [3 + i]^2 = [3 + i][3 + i] = 9 + 6i + i^2 → 9 + 6i - 1 → 6i + 8](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B3%20%2B%20i%5D%5E2%20%3D%20%5B3%20%2B%20i%5D%5B3%20%2B%20i%5D%20%3D%209%20%2B%206i%20%2B%20i%5E2%20%E2%86%92%209%20%2B%206i%20-%201%20%E2%86%92%206i%20%2B%208)
Therefore, the d-value is 6.
