Answer:
D
Step-by-step explanation:
To inverse a function, switch the y for x and x for y and solve for y
f(x) = 2/(x-3)
y = 2/(x-3)
x = 2/(y-3)
x*(y-3) = 2
y-3 = 2/x
y = 2/x-3
y = 2/x - 3x/x
y = 2+3x/x

I believe the original price of the television was 580.56 because 492*18%=88.56 so 492+88.56=580.56 hope this helps
Answer:
first choice
Step-by-step explanation:
make 1/3 and 1/2 a common denominator, which is 6.
1x2
- = 2
-
3x 2 6
1 x 3
- = 3
-
2 x 3 6
now u have 2/6, and 3/6
u subtract 2/6 by 3/6 since ur finding a solution to an inequality. remember to do the opposite sign.
2/6-2/6 = 0 (u cancel that out)
3/6 - 2/6 = 1/6
now u have
q>1/6
since there's no 1/6 the first choice is the most accurate
We know that
<span>The cosine of the sum of two angles </span><span>is defined by the following trigonometric identity
</span>cos(A + B) = cos A cos B − sin A sin <span>B
A=60</span>°
B=105°
cos A=cos 60
cos B=cos 105
sin A=sin 60
sin B=sin 105
then
cos(60 + 105) = cos 60 cos 105 − sin 60 sin 105
cos(165) = cos 60 cos 105 − sin 60 sin 105
the answer is
cos (105°)
