Order the steps and justifications in solving the system of linear equations. Equation 1: -2x +y=7
Equation 2: 2x + y = -9

two data sets with the same median will not have the same varaibility

step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
