Step-by-step explanation:
- 2x + 4 + 3 = -4
-2x+7= -4
-2x= -4-7
-2x= -11
x=-11/-2
x=11/2
x=5.5 (if u want the answer in decimal form)
That's actually tough
Answer:
my putyy
ong its my putty hehehe
cos x=sin 2x
sin 2x-cos x=0
2 sin x cos x-cos x=0
cos x(2 sin x-1)=0
either cos x=0
or
2 sin x-1=0
54
y= -3.5x+57.5.
