Answer:
The inverse is 1/3x-2
Step-by-step explanation:
y = 3x+6
Exchange x and y
x = 3y+6
Solve for y
Subtract 6 from each side
x-6 = 3y+6-6
x-6 = 3y
Divide by 3
x/3 -6/3
1/3x -2 = y
The inverse is 1/3x-2

Answer:
2 < x < 5
Step-by-step explanation:
<u>< This symbol means 'less than'</u>. The number you put on its left side is less than the number on its right side.
<u>> This symbol means 'greater than'</u>. The number put on its left is greater than its number on the right.
Think of them like a mouth. Remember the 'open side' wants to eat more.
Translate words to symbols:
'x is less than 5'
x < 5
'x is greater than 2'
x > 2
Put them together. The < and > symbols change directions, but x on the closed side of 5. Keep x on the open side of 2.
2 < x < 5
Don't confuse < and > with ≤ and ≥.
≤ and ≥ mean 'less than OR equal to' and greater than OR equation to'.
Answer:
sin(2x)/cos x = 2sin x*cos x/ cos x = 2 sin x = 2
sin x = 1
x = pi/2
but cos pi/2 = 0
so the given equation is indeterminate for x = pi/2
