Answer this question showing work. 2b − 7 ≥− 14 + 2b
jeka94

Answer:

No solution

Step-by-step explanation:

This answer has no solution, follow these steps to see how.

First, you add 7 on both sides.

Then you should have 2b > -7 +2b

You see how there is a 2b on both sides? this makes the problem unsolvable.

Say you were to continue though. You would subtract 2b on both sides and end up getting 0 > -7.  Therefore there is no solution.

denis23 [38]

Answer:

449.25 units

Step-by-step explanation:

The amount of profit, y, made by the company, is  related to the selling price of each widget, x, by the given equation as follows :

y=-x^2+51x-201 ...(1)

For maximum profit,

Put dy/dx = 0So,

\dfrac{d}{dx}(-x^2+51x-201)=0\\\\-2x+51=0\\\\x=\dfrac{51}{2}\\\\x=25.5

Now put x = 25.5 in equation (1).

y=-(25.5)^2+51(25.5)-201\\\\y=\$ 449.25

so, the required answer is 449.25 units.
