I think the correct answer from the choices listed above is option C. <span>The graph of a system of equations with the same slope and the same y-intercepts will never have no solutions. Rather, it has an infinite number of solutions since all points of the lines intersects.</span>
Answer:
The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds
Step-by-step explanation:
Let
x ----> amount of 65 cents per pound flour to use
y----> amount of 95 cents per pound flour to use
we know that
---->
----> equation A
----> equation B
substitute equation A in equation B
![0.65x+0.95(100-x)=0.83(100)](https://tex.z-dn.net/?f=0.65x%2B0.95%28100-x%29%3D0.83%28100%29)
Solve for x
![0.65x+95-0.95x=83](https://tex.z-dn.net/?f=0.65x%2B95-0.95x%3D83)
![0.95-0.65x=95-83](https://tex.z-dn.net/?f=0.95-0.65x%3D95-83)
![0.30x=12](https://tex.z-dn.net/?f=0.30x%3D12)
![x=40\ lb](https://tex.z-dn.net/?f=x%3D40%5C%20lb)
Find the value of y
![y=100-40=60\ lb](https://tex.z-dn.net/?f=y%3D100-40%3D60%5C%20lb)
therefore
The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds
Answer:
<h2>-28
°</h2>
Step-by-step explanation:
