Complete the square by using the following form:
![(x+\frac{b}{2})^2 = x^2 +bx+(\frac{b}{2})^2](https://tex.z-dn.net/?f=%28x%2B%5Cfrac%7Bb%7D%7B2%7D%29%5E2%20%3D%20x%5E2%20%2Bbx%2B%28%5Cfrac%7Bb%7D%7B2%7D%29%5E2%20)
![y = (x^2 -6x) +16 \\ \\ y = (x^2 -6x+9) + 16 - 9 \\ \\ y = (x-3)^2 + 7](https://tex.z-dn.net/?f=y%20%3D%20%28x%5E2%20-6x%29%20%2B16%20%5C%5C%20%20%5C%5C%20y%20%3D%20%28x%5E2%20-6x%2B9%29%20%2B%2016%20-%209%20%5C%5C%20%20%5C%5C%20y%20%3D%20%28x-3%29%5E2%20%2B%207)
The vertex is at (3,7)
The squared term is positive so it opens up and vertex is a minimum.

Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
Because 4/3=4*4/3*4=16/12
Y - 4 = - 3x + 6
y = - 3x + 10
slope = - 3
Answer:
x = 74 degrees
Step-by-step explanation:
180 - 32 = 148
148 / 2 = 74
