Answer:
x=7
Step-by-step explanation:
The percentage discount from the base price result is 2.16%.
<h3>How to compute the value?</h3>
Discount percent will be:
= (Base price - New price)/Base price × 100
= (9.40 - 9.20)/9.40 × 100
= 0.20/9.40 × 100
= 2.16%
The new price will be:
= Base price - (2.16% of base price)
= 9.40 - (2.16% × 9.40)
= 9.20
Therefore, the percentage discount from the base price result is 2.16%.

<u>Complete question:</u>
A rodent infestation has left a landlord with a major cleanup job; in fact, the cleanup will consist of ripping out all the walls and ceilings of an 1860-square-foot house to replace them. A trip to the local home improvement store reveals that 4'x8' sheets of drywall have three price points as indicated in the table. Another consideration for the landlord is that he is equipped with only a humble half-ton pickup truck, that can hold at most 20 sheets. His truck sips fuel, so he considers only wear and tear on his vehicle at $5 to haul all the sheets he will use for the job. The holding percentage is 20%. The landlord believes the entire job - all walls and ceiling - will require 10,080 square feet of drywall.
Consider the $9.40 per sheet figure as the base price and use the information in Scenario 11.4 to answer the following question. What percentage discount from the base price results in an optimal order quantity of 101 sheets?
1.42%
2.16%
2.03%
1.86%
Step-by-step explanation:
Let's start with solving for line L using slope-intercept form (y=mx+b)
We can see that the y-intercept is 4, and the slope is rise/run. From point (5,2) to (0,5), the rise is 2, and the run is -5 (it goes backwards 5).
Using this, we can form our equation for Line L: y = -2/5x + 4
Now let's solve for Line M.
There is something very important to notice before we jump into this. Both of these lines (Line L and M) are parallel (they never touch) and therefore will contain the same slope as each other (-2/5). The y-intercept for this equation we can see is -1, as the line touches (0,-1). Now lets form our equation;
Line M: y = -2/5+4
Solving a system of equation means to find two (or more) line's interceptions on a graph (where they meet/touch). Because both of these lines are parallel and never touch each other, there is no definite answer. Therefore our answer is No Solutions.
Answer:
![f(x)=2^x - 3](https://tex.z-dn.net/?f=f%28x%29%3D2%5Ex%20-%203)
Step-by-step explanation:
The choices are all exponentials, the x is raised to a power.
First of all, an exponential in the form:
![f(x)=a^x](https://tex.z-dn.net/?f=f%28x%29%3Da%5Ex)
Where (a > 1)
Would have this shape and it will go through (0,1)
Now, looking at the graph, we see that it is translated 3 units down from (0,1).
The basic graph is
and the translated one would be:
![f(x)=2^x - 3](https://tex.z-dn.net/?f=f%28x%29%3D2%5Ex%20-%203)
<u>NOTE:</u>
Basically is this is vertically translated a units down, the equation becomes:
![f(x)=2^x-a](https://tex.z-dn.net/?f=f%28x%29%3D2%5Ex-a)
and if translated a units up, the equation would be:
![f(x)=2^x+a](https://tex.z-dn.net/?f=f%28x%29%3D2%5Ex%2Ba)
