Answer:
step 2
and then also in step 3 compensating the error in step 2
Step-by-step explanation:
I think I just answered this for another post.
sin(a - b) = sin(a)cos(b) - cos(a)sin(b)
so, step 1 is correct :
sin(A - 3pi/2) = sin(A)cos(3pi/2) - cos(A)sin(3pi/2)
but step 2 suddenly and incorrectly switched that central "-" to a "+".
yes, sin(3pi/2) = -1, but that is still an explicit factor in step 2. so it was not used to flip the central operation from subtraction to addition, and therefore this change was a mistake.
then, in step 3, another error was made by just ignoring the "-" sign of "-1" and still keeping the central "+" operation. this error compensated for the error in step 2 bringing us back by pure chance to the right result.
y = -2x + 1
y = -2x -3
none cuz they're both -2x
Answer:
3/4 of the way from A to B = 
or (-3.5, 1.25)
Step-by-step explanation:
Please see attached images below for explanation:
x/3>-1
Isolate the x. Multiply 3 to both sides
(x/3)3 > -1(3)
x > -1(3)
x > -3
x > -3 is your answer
hope this helps
