Solve the system and write the solution as an ordered pair.

6u+5v=-2
2u+3v=6

Step-by-step explanation:

6u+5v=-2 => ×1 => 6u + 5v = -2

2u+3v=6 => ×3 => 6u + 9v = 18

-

-4v = -20

=> v = -20/-4 = 5

2u +3v = 6

2u +3(5)=6

2u +15 = 6

2u = -9

u = -9/2 = -4.5

so, the solutions : {(-4.5 , 5)}

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
