Answer: The graph is shifted vertically, but not horizontally
Step-by-step explanation:
Since the added constant is outside the x term, the constant will only shift the graph vertically.
To Find :
How many gallons of a 80% antifreeze solution must be mixed with 100 gallons of 20% antifreeze to get a mixture that is 70% antifreeze.
Solution :
Let, x gallons of 80% antifreeze solution is required :
So,
![(x \times 80) + ( 100 \times 20 ) = (x + 100 )\times 70\\\\8x + 200 = 7( x + 100)\\\\x = 500](https://tex.z-dn.net/?f=%28x%20%5Ctimes%2080%29%20%2B%20%28%20100%20%5Ctimes%2020%20%29%20%3D%20%28x%20%2B%20100%20%29%5Ctimes%2070%5C%5C%5C%5C8x%20%2B%20200%20%3D%207%28%20x%20%2B%20100%29%5C%5C%5C%5Cx%20%3D%20500)
Therefore, 500 gallons of 80% antifreeze solution is required.
The value of the digit 4 is worth 4,000 in the number 84,230.
0.5x + 78.2 = 287
-78.2 -78.2
subtract 78.2 on both sides you will then get 0.5x = 208.8 you will then divide by 0.5 and the answer is x = 417.6
