Simplify sin(3pi minus x)
Slav-nsk [51]

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

Re-write the quadratic function below in Standard Form y= -9(x+3)2+2
disa [49]

Answer:

18x+y=-52

Step-by-step explanation:

we all know and love(being 100% sarcastic here)the standard form  as

ax+by=c

y=-9(x+3)*2+2----This is weird and not so nice

so lets make it nice by distributing the 9::::

y=(-9x-27)2+2

and now the 2:

y=-18x-54+2

y=-18x-52

oops this is NOT in S.F we got to switch the -52 and y

52=-18x-y

-18 cant be neg. so we have to divide by -1 on both sides

-52=18x+y

18x+y=-52

HOPE THIS HELPS
