Pythagoras was the greek geometer.
Step-by-step explanation:
2sin(x)cos(x) - sin(x) + 2cos(x)-1= 0
<=> sinx( 2cosx -1) + ( 2cosx -1) =0
<=> (sinx +1) + ( 2cosx-1)=0
<=> sinx=-1 or cosx= 1/2
+) sinx=1 => x= pi/2 + k×2pi
+)cosx=1/2 => x= pi/3+ k×2pi or x=-pi/3 + k×2pi
x€ [0,2pi] => x= pi/2, pi/3.
Is there a diagram with this question?
ANSWER WITH STEPS:
Let's solve for x.
5x−10y=−5
Step 1: Add 10y to both sides.
5x−10y+10y=−5+10y
5x=10y−5
Step 2: Divide both sides by 5.
5x
5
=
10y−5
5
x=2y−1
Answer:
3/12 > 2/9
Step-by-step explanation:
Well, 3/12 in decimal form is 0.25, and 2/9 in decimal form is around 0.23 so that would make 3/12 the greater fraction.
