Answer:
Depends on what you mean by 1/4x (see below)
Step-by-step explanation:
For 1/4(x)
1/4x+5 = 4 -> subtract 5 from both sides
1/4x = -1 -> multiply both sides by 4
x = -4
OR
For 1/(4x)
1/4x+5 = 4 -> subtract 5 from both sides
1/4x = -1 -> cross multiply (-1 = -1/1)
-4x = 1 -> divide both sides by -4
x = -1/4
The answer is B.
If you multiply x by 2 then you should get y.
Cos x = 15/21
X= cos^-1 (15/21)
X=44
Answer: yes it should be C
