Answer:
x = -5/6
Step-by-step explanation:
Multiply both sides by (3x+1):
3x - 2 = 3 (3x + 1)
Distribute:
3x - 2 = 9x + 3
Add 2 to both sides:
3x = 9x + 5
Subtract 9x from both sides:
-6x = 5
Divide both sides by -6:
x = -5/6
5 x 5 x 5
Expanded just means writing it out as you would solve it. So solving a cube would be multiplying the number by itself 3 times
Answer:
The inverse function is
Step-by-step explanation:
Inverse of a function:
To find the inverse of a function, we exchange x by y, then we isolate y.
y = -4x
Finding the inverse:
So
The inverse function is
The percentage of profit margin that
the plumbing supplies manager realizes that he has = 15%
Total sales for the month made by the plumbing supplies manager = $23000
Then
Amount of profit that has been made
by the plumbing sales manager = 15% * 23000 dollars
= (15/100) * 23000 dollars
= 15 * 230 dollars
= 3450 dollars
So the plumbing manager makes a profit of $3450 in the month as can be seen from the above deduction.
