Answer:
-x^2-2xy-3x
Step-by-step explanation:
Answer:
m=0.19
Step-by-step explanation:
To work this out you would divide 0.95 by 5. this is because 0.95 is equal to 5*m and so so work out m you would divide 0.95 by 5.
hmmm we know B (2 , 1), and let's say the y-coordinate is "y" for A, so A (-10 , y).
![~~~~~~~~~~~~\textit{distance between 2 points} \\\\ B(\stackrel{x_1}{2}~,~\stackrel{y_1}{1})\qquad A(\stackrel{x_2}{-10}~,~\stackrel{y_2}{y})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ BA=\sqrt{[-10 - 2]^2 + [y - 1]^2}\implies 13=\sqrt{(-12)^2+(y^2-2y+1)} \\\\\\ 13^2=(-12)^2+(y^2-2y+1)\implies 169=144+y^2-2y+1 \\\\\\ 169=y^2-2y+145\implies 0=y^2-2y-24 \\\\\\ 0=(y-6)(y+4)\implies y= \begin{cases} 6\\ -4 \end{cases}~\hfill A= \begin{cases} (-10~,~6)\\ (-10~,~-4) \end{cases}](https://tex.z-dn.net/?f=~~~~~~~~~~~~%5Ctextit%7Bdistance%20between%202%20points%7D%20%5C%5C%5C%5C%20B%28%5Cstackrel%7Bx_1%7D%7B2%7D~%2C~%5Cstackrel%7By_1%7D%7B1%7D%29%5Cqquad%20A%28%5Cstackrel%7Bx_2%7D%7B-10%7D~%2C~%5Cstackrel%7By_2%7D%7By%7D%29%5Cqquad%20%5Cqquad%20d%20%3D%20%5Csqrt%7B%28%20x_2-%20x_1%29%5E2%20%2B%20%28%20y_2-%20y_1%29%5E2%7D%20%5C%5C%5C%5C%5C%5C%20BA%3D%5Csqrt%7B%5B-10%20-%202%5D%5E2%20%2B%20%5By%20-%201%5D%5E2%7D%5Cimplies%2013%3D%5Csqrt%7B%28-12%29%5E2%2B%28y%5E2-2y%2B1%29%7D%20%5C%5C%5C%5C%5C%5C%2013%5E2%3D%28-12%29%5E2%2B%28y%5E2-2y%2B1%29%5Cimplies%20169%3D144%2By%5E2-2y%2B1%20%5C%5C%5C%5C%5C%5C%20169%3Dy%5E2-2y%2B145%5Cimplies%200%3Dy%5E2-2y-24%20%5C%5C%5C%5C%5C%5C%200%3D%28y-6%29%28y%2B4%29%5Cimplies%20y%3D%20%5Cbegin%7Bcases%7D%206%5C%5C%20-4%20%5Cend%7Bcases%7D~%5Chfill%20A%3D%20%5Cbegin%7Bcases%7D%20%28-10~%2C~6%29%5C%5C%20%28-10~%2C~-4%29%20%5Cend%7Bcases%7D)
Answer:
If the conclusion is false, then one or more of the premises must also have been false.
Step-by-step explanation:
One important distinguishing feature of valid arguments is that - if the conclusion is false, then one or more of the premises must also have been false.
An argument form is said to be valid, if and only if, when all premises are true, then the conclusion is true.
