Answer: 4) y = -1/3x² + 2x - 1
Step-by-step explanation:
Given :
y = 
+ 2
Expanding (x-3)² will give :
- 6x + 9
substituting into the function , we have :
y = 
- 6x + 9 ) + 2
Expanding , we have
y = 
+ 2x - 3 + 2
y = 
+ 2x - 1
That is the Pythagorean’s theorem, used to find the largest side on a right (90 degree) triangle.
Answer:
-4 is the slope
Step-by-step explanation:
equation is y=mx + b
m = slope
b= y intercept
It's C. For the congruent sides are the ones across from it and below it. Hope this helps.
