Hey there!!
To check whether x= -4, let's solve the equation.
Given:
3x+7 = x-1
Subtracting 2x on both sides:
2x + 7 = -1
Subtracting 7 on both sides:
2x = -1-7
2x = -8
Dividing 2 on both sides:
x = -8/2
x = -4
<u><em>Yes, x is -4. </em></u>
<u><em>Hope it helps!</em></u>
Answer:
c i think
Step-by-step explanation:
Answer:
Yes D is the correct answer :)
Cos (π/2 - x) = sin x = 3/5
tan x = sin x / cos x = 3/5 / 4/5 = 3/4
csc x = 1/sin x = 1 / 3/5 = 5/3
sec x = 1/cos x = 1 / 4/5 = 5/4
cot x = 1/tan x = 1 / 3/4 = 4/3.
