Hi again!
2x + y > 8
The correct answer is option D
-------------------------------------------
Honestly I don't think we can solve the equation to find the answer. What we can do is to find the boundary line. (I think you know what that is) After that, shading the appropriate area.
y > -2x + 8
Again, credit to my beautiful graphing calculator. Here is how it looks like.
Answer:
A character is offered five different jobs. They all include an hourly wage, as well as a set weekly base pay. One example is a job that pays $8.50 an hour, plus an additional $25 bonus for the week. (Weekly base pay is what you automatically get paid for working the entire week. A bonus is money you earn in addition to the weekly base pay.) Story Starter 2: A character is searching for the best cell phone plan to buy. One plan costs $25 a month, plus $0.89 per minute used. Story Starter 3: A character is trying to decide which cab to choose from the five available. All the cabs have different rates per mile. They also charge different flat rates in addition to the rates per mile. One cab is offering a rate of $0.75 per mile, plus a flat fee of $25.
Step-by-step explanation:
A quadratic function is a function of the form
![f(x)=ax^2+bx+c](https://tex.z-dn.net/?f=f%28x%29%3Dax%5E2%2Bbx%2Bc)
. The
vertex,
![(h,k)](https://tex.z-dn.net/?f=%28h%2Ck%29)
of a quadratic function is determined by the formula:
![h= \frac{-b}{2a}](https://tex.z-dn.net/?f=h%3D%20%5Cfrac%7B-b%7D%7B2a%7D%20)
and
![k=f(h)](https://tex.z-dn.net/?f=k%3Df%28h%29)
; where
![h](https://tex.z-dn.net/?f=h)
is the
x-coordinate of the vertex and
![k](https://tex.z-dn.net/?f=k)
is the
y-coordinate of the vertex. The value of
![a](https://tex.z-dn.net/?f=a)
determines if the <span>
parabola opens upward or downward; if</span>
![a](https://tex.z-dn.net/?f=a)
is positive, the parabola<span> opens upward and the vertex is the
minimum value, but if </span>
![a](https://tex.z-dn.net/?f=a)
is negative <span>the graph opens downward and the vertex is the
maximum value. Since the quadratic function only has one vertex, it </span><span>could not contain both a minimum vertex and a maximum vertex at the same time.</span>
