I need help fast... if answered Correctly I will mark brainliest Choose the ordered pair which is the solution to: -2x + 7y = 17 and 3x - 4y = -19.

O (0,17/7)
O (-1,-2)
O (-5,1)
O (-1,3)

9514 1404 393

  (-5,1)

Step-by-step explanation:

To eliminate x, multiply the first equation by 3 and add 2 times the second equation.

  3(-2x +7y) +2(3x -4y) = 3(17) +2(-19)

  -6x +21y +6x -8y = 51 -38

  13y = 13

  y = 1 . . . . . matches the third answer choice

  (x, y) = (-5, 1)

i'm not entirely sure

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
