Try first column:-
5 - 2 = 1/4(x + 8)
3 = 1/4x + 2
1/4x = 1
x = 4
B is the correct choice
65+20=85 150-85=65
She will have 65$ left over
The equation can be
65+20=85
Or
150-85
Or
65+20=85 150-85=65
It depends on the option. I hope this helped

Step-by-step explanation:
Alright, archtan /
tan
−
1
(
x
)
is the inverse of tangent. Tan is
sin
cos
. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.
Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.
Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.
Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.
