Answer:
x=4
Step-by-step explanation:
divide both sides by 3
-2x • 3x = -6x2 (the 2 is an exponent)
4y • -7y = -28y2 (the 2 is an exponent)
-2x • -7y = 14xy
4y • 3x = 12xy
14xy + 12xy = 26xy
—> -6x2(expo) - 28y2(expo) + 26xy
Check the answer again just to be sure, it’s been a while since I’ve had algebra!
Answer:
C , D , B
Step-by-step explanation:
Trigonometry is given by three formulas :
SOH - CAH - TOA
- Sin x = Opp/Hyp
So Sine must be Option D - Cos x = Adj/Hyp
So Cosine must be Option C - Tan x = Opp/Adj
So tangent must be Option B
Hope this helped and have a good day
Cosine is positive in Quadrant IV.
