Step-by-step explanation:
(-2,0) option b is the correct answer
706,421 rounded to the nearest thousand is 706,000 because the 421 is less than 500 so the 6 would remain a 6.
If you simplify what's in the bracket, you get 3n
=(3n)+4=32/2
=3n+4= 32/2(here we can either crossmultiply or equate)
3n+4-4=32/2-4(subtract 4 from both sides)
3n=32/2-4
3n=24/2
3n=12
3n=12(divide both sides by the coefficient of the unknown)
3n/3=12/3
n=4
Use the identity: 
and solve for 
. You get: 
Do the substitution on the left side to get:
