Answer:
sinx
Step-by-step explanation:
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
Answer:
19
----- = x
40-3a
Step-by-step explanation:
3(ax + 9) = -4 (-2 - 10x)
Distribute
3ax +27 = 8+40x
Subtract 3ax from each side
3ax-3ax +27 = 8+40x-3ax
27 = = 8+40x-3ax
Subtract 8 from each side
27-8 = 8-8+40x-3ax
19 = 40x-3ax
Factor an x on the right side
19 = x(40-3a)
Divide each side by 40-3a
19/(40-3a) = x(40-3a)/(40-3a)
19
----- = x
40-3a
