Answer:
(3.25, 1.5)
Step-by-step explanation:
<em><u>First, turn the 2nd equation into y=mx+b form:</u></em>
у+ 2x = 8
<u> -2x -2x</u>
y = -2x + 8
<u><em>Next Substitute:</em></u>
З(-2x+8) - 2x = -2
-6x + 24 - 2x = -2
-8x + 24 = -2
<u><em>Then simplify:</em></u>
-8x + 24 = -2
<u> -24 -24</u>
-8x = -26
x = 3.25
<em><u>Lastly, substitute x into any one of the original equations:</u></em>
y + 2 (3.25) =8
y + 6.5 = 8
<u> - 6.5 - 6.5</u>
y = 1.5
please give me brainliest i worked hard on this :,)
and its 1000% correct, i checked it i promise
Answer:
The company needs to sell either 30 or 40 items.
Step-by-step explanation:
We are given that the cost for selling <em>x</em> items given by the function:

And the revenue for selling <em>x</em> items is given by:

The profit function is the cost function subtracted from the revenue function:

Substitute and simplify:

To find how many items must be sold in order to obtain a weekly profit of $300, we can let <em>P</em> equal 300 and solve for <em>x</em>. So:

Solve for <em>x</em>. Subtract 300 from both sides:

We can divide both sides by -0.4:

Factor:

Zero Product Property:

Solve for each case:

So, in order to obtain a weekly profit of $300, the company need to sell either 30 <em>or</em> 40 items.
