Using the linear combination method, what is the solution to the system of linear equations 7x-2y--20 and 9x+4y=-62
(-3,2)
(-2,3)
(2, -3)
(3,-2)

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

lockers 1, 4, 9, 16, 25, 40, and 49 are open
