hello :

note :

for all x in ℝ : 1) sin(x+2π) = sinx 2) sin(π-x) = sinx

in this exercice :

3π - x = 2π+(π - x)

sin(3π - x) = sin(2π +(π - x)) =sin(π-x) = sinx

HELP ME PLEASE NEED ANSWER NOWWWWWWWWWW solve the following system of equation. Round your answer to the nearest tenth. Your ans

dlinn [17]

(A) 5x+2y=21
(B) -2x+6y=-34

multiply (A) by - 3→ -15x - 6y = - 63 (C)

Now add (C) to (B):

-15x - 6y = - 63 (C)
-2x + 6y =-34 (B)
----------- --------
-17x = - 97 and x = 97/17

Now replace x value in any of the equation and you'll find y = - 64/17

1st Answer (97/17 , - 64/17)
2nd Answer : 97/17 + (-64/17) = 97/17 - 64/17 = 33/17 ≈ 2
