- Midpoint Formula:

Given our two points, (-3,9) and (-1,4), we can apply them to the midpoint formula and solve for it as such:

<u>Your midpoint is (-2,6.5)</u>
I think your answer is the second one
best of luck
X-intercepts are where the parabola touches the x-axis so are the roots. (X^2)+4x-60=0 ; (x-6)(x+10) =0; x-6=0 so x=6 and x+10=0 so x=-10.
The median would be 5.5 in the data set!
Times by 3. Then divide the top backup by 3 to get 9/30. 9/30+9/30+9/30=27/30=9/10.
