I'm guessing you're trying to simplify the equation since there is no other information lol
[(2x+y)-3]
So basically when you are trying to simplify equations you have to add the same variables together (In this case X & Y) But since there are no alike variables there really is nothing to add
So your answer would be 2x+y-3
Hoped this helped
I think it’s C but i’m not sure

Answer:
14 days
Step-by-step explanation:
Total Problems = 175
Finished Problems = 8
Remaining = 175 - 8 = 167
8 problems in 30 minutes, means:
30/8 = 15/4 = 3.75 minutes per problem
If he works for 45 minutes, at that rate, he can solve:
45/3.75 = 12 problems per day
To finish 167 problems, he will need:
167/12 = 13.91
Rounded, that is <u>14 days more to finish</u>
The correct question is
<span>Given cos theta=4/9 and csc theta < 0 find sin theta and tan theta
</span>
we know that
csc theta=1/sin theta
if csc theta < 0
then
sin theta < 0
we have that
<span>cos theta=4/9
we know that
sin</span>² theta+cos² theta=1
so
sin² theta=1-cos² theta-----> 1-(4/9)²----> 1-(16/81)----> 65/81
sin theta=-√(65/81)---->-√65/9
the answer Part a) is
sin theta=-√65/9
Part b) find tan theta
tan theta=sin theta/cos theta
tan theta=(-√65/9)/(4/9)-----> tan theta=-√65/4
the answer part b) is
tan theta=-√65/4
