Answer:
y=2/-1+8
Step-by-step explanation:
- -4= (-4,0) -4=x1 0=y1, 8= (0,8) 0=x2 8=y2
- formula is, y2-y1/x2-x1
- 8-0/0-4=8/-4=4/-2= 2/-1
- 2/-1 is the slope or (m), use (-4,0) or (0,8) i used (0,8) because its easier.
- (0,8), 0=x1 8=y1
- formula is y-y1=m(x-x1)
- y-8=2/-1(x-0) ---->distribute
- y-8=2/-1x-0 --->get y alone
+8 +8
- so the answer is y=2/-1+8

Answer: ![4\sqrt{3}](https://tex.z-dn.net/?f=4%5Csqrt%7B3%7D)
Step-by-step explanation:
For this exercise it is important to remember the following:
![i=\sqrt{-1} \\\\i^2=-1](https://tex.z-dn.net/?f=i%3D%5Csqrt%7B-1%7D%20%5C%5C%5C%5Ci%5E2%3D-1)
Given the following expression:
![-2i\sqrt{-12}](https://tex.z-dn.net/?f=-2i%5Csqrt%7B-12%7D)
You can notice that the radicand (the number inside the square root) is negative. Therefore, in order to simplify the expression, you need to follow these steps:
1. Replace
with
and simplify:
![(-2i)(i)\sqrt{12}=-2i^2\sqrt{12}=-2(-1)\sqrt{12}=2\sqrt{12}](https://tex.z-dn.net/?f=%28-2i%29%28i%29%5Csqrt%7B12%7D%3D-2i%5E2%5Csqrt%7B12%7D%3D-2%28-1%29%5Csqrt%7B12%7D%3D2%5Csqrt%7B12%7D)
2. Descompose 12 into its prime factors:
![12=2*2*3=2^2*3](https://tex.z-dn.net/?f=12%3D2%2A2%2A3%3D2%5E2%2A3)
3. Substitute into the expression:
![=2\sqrt{2^2*3}](https://tex.z-dn.net/?f=%3D2%5Csqrt%7B2%5E2%2A3%7D)
4. Since
, you can simplify it:
![=(2)(2)\sqrt{3}=4\sqrt{3}](https://tex.z-dn.net/?f=%3D%282%29%282%29%5Csqrt%7B3%7D%3D4%5Csqrt%7B3%7D)
Answer: Tammy's sample may not be vaild because she surveyed the students only from her class and it is likely that other classes might not like the subject maths. She might get the accurate results by surveying a larger number of people in the school instead of just her class.
Answer:
Negative since the line is coming like this \
It gets to be negavite will if it was like this/ it could have been positive
