First find the slope. 4+1/3-2 = 5/1 or 5. Plug in your points to find b. 4=5(3)+b. 4=15+b. b=-11. SO the equation is y=5x-11.
Answer:
BC≈8,38
Step-by-step explanation:
AB=a
BC=c
CA=b
a²+b²=c²
3.3²+7.7²=c²
√70,18=√c²
c≈8,38
It sucks that points have to be used in order to post questions.
Openstudy - the company that merged into Brainly - was much better.
Anyway, I think that the answer to this question is A. I'm not sure, though.
The square root of 0.0036 can be calculated through the calculator. The answer is 0.06. WE can also take by the eye the square root of 0.0036 in which the square root of 36 is 6. The number must be greater than 0.0036. The answer is 0.06.
