2. The amount of fertilizer in a landscaping company’s warehouse decreases at a rate of 3% per week. The amount of fertilizer in

the warehouse was originally 78,000 cubic yards. What function models the amount of fertilizer in cubic yards left after w weeks?
Exponential Growth: y=a*b^x where a initial amount and b is the growth factor.
Sarah identified the initial amount as 78000 and the rate as 3%. She wrote her equation as: y=78,000 〖(3)〗^x.


Error:

Correct solution:

The error is the way she wrote 3%

3% = 0.03

The correct equation should be y = 78,000(0.03)^x

Explain why their are no solutions to the system of inequalities <br> y ≤2x-5 <br> y ≥2x+1
rosijanka [135]

Answer:

Sorry this is late and I think this is right.

They are both parallel, they have the same slope, and do <em>not </em>intersect. If you were to draw a slope out for it, you would find this to be true.

For example: Say the question called for you to explain why there aren't any solutions to these system of inequalities:

<em>y < - 1/2x -3</em>

<em>y > 1/2x + 2</em>

<em>y= -x/2 -3</em> and <em>y= -x/2 + 2 </em>have the same exact slope, are parallel, and never intersect. The first line is 5 units below the second line when x = 0. Because the lines are parallel, it is always below the second line. The solutions of y < - x/2 -3 are the points in the plane below the first line. The solutions of y > 1/2 + 2 are points above the second line.

I hope this helps you. Good luck on whatever you're working on and stay safe! Please let me know if this helped you or didn't.

Mitch is buying candy bars for his friends. He wants to give 2 bars to each friend, and he wants to have 10 spare. He can afford
Xelga [282]

Hi!


So we know that he has 20 candy bars.

= 20


He wants to give 2 to each friend. So 2 candy bars x friends.

2f


He's going to keep 10.

+10


Put all of the parts together.

2f + 10 = 20


The answer is 2f + 10 = 20


Hope this helps!
