810
Step-by-step explanation:
multiple 3x3 9 then multiple 3x9 27 multiply 27x3 equal 81 then add zero 810
Answer:
D.
Step-by-step explanation:
You pass 3x to the other side so you get 4y = -16 - 3x
to clear y you divide both sides by 4
y = (-16-3x )/ 4
you can simplify this so it so it gives us
y = -4 - 3/4x
The solution to the given equations has infinitely many solutions
Given the following set of equations:
y = 9x - 5
y = 9x + 6
Equating both expressions
9x - 5 = 9x + 6
Collect the like terms
9x - 9x = 6 + 5
0x = 11
x = 11/0
x = ∞
This shows the solution has infinitely many solutions

The two black circles represents "The selling prices that produces no profit." If the selling is 10, the profit is 0. If the selling price is 60, the profit is 0.
The selling price that provides the maximum profit is represented by the red dot. It is between the selling price of 30 and 40. Its maximum profit is equal to 12,000.
Subtract 3
-6x = 42
Divide by -6
x = -7
