Answer:
(-8 , 27)
Step-by-step explanation:
![(-6,23)= (x ,y )\\\\(-4 ,19)=(x_1,y_1)\\\\x = \frac{x_1+x_2}{2}\\ \\-6 = \frac{-4+x_2}{2}\\ \\-12 =-4+x_2\\\\-12+4 =x_2\\-8=x_2\\\\y = \frac{y_1+y_2}{2}\\ \\23 = \frac{19+y_2}{2} \\\\46 =19+y_2\\\\46-19=y_2\\27=y_2](https://tex.z-dn.net/?f=%28-6%2C23%29%3D%20%28x%20%2Cy%20%29%5C%5C%5C%5C%28-4%20%2C19%29%3D%28x_1%2Cy_1%29%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%5C%5C%20%5C%5C-6%20%3D%20%5Cfrac%7B-4%2Bx_2%7D%7B2%7D%5C%5C%20%5C%5C-12%20%3D-4%2Bx_2%5C%5C%5C%5C-12%2B4%20%3Dx_2%5C%5C-8%3Dx_2%5C%5C%5C%5Cy%20%3D%20%5Cfrac%7By_1%2By_2%7D%7B2%7D%5C%5C%20%5C%5C23%20%3D%20%5Cfrac%7B19%2By_2%7D%7B2%7D%20%5C%5C%5C%5C46%20%3D19%2By_2%5C%5C%5C%5C46-19%3Dy_2%5C%5C27%3Dy_2)
Answer:
(1/2, 9/2)
Step-by-step explanation:
Using the midpoint formula
![\left(\frac{-4+5}{2},\:\frac{6+3}{2}\right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cfrac%7B-4%2B5%7D%7B2%7D%2C%5C%3A%5Cfrac%7B6%2B3%7D%7B2%7D%5Cright%29)
=![\left(\frac{1}{2},\:\frac{9}{2}\right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cfrac%7B1%7D%7B2%7D%2C%5C%3A%5Cfrac%7B9%7D%7B2%7D%5Cright%29)
Yes, <span>53.33/3=17.776666</span>
Not a function because of the vertical line test.
Domain is [-2,∞] since the left most point is -2 and the right is unbounded.
Range is (-∞,∞) since it is not bounded in terms of y.
