The two graphs have the same slope. But the graph of <span>y= x – 12 is 12 units below the graph of y = x. We call that a "vertical translation."
</span>
Answer:
4x+16
Step-by-step explanation:
Just multiply x and 4 by 4 to get your answer.
The other family is traveling at 900 miles per day while your family is traveling at 950 miles per day. So your family is traveling faster.
1)We need to know the amount of yellow tint in the old mixture.
amount of yellow tint=30% of 40 liters
30%=30/100=0.3
Amount of yellow tint=0.3(40 liters)=12 liters.
2)We need to find the amount of yellow tint in the new mixture.
amount of yellow tint in the new mixture=12 liters + 9 liters=21 liters.
3) we calculate the amount of the new mixture:
amount of new mixture=40 liters + 9 liters=49 liters
4) we compute the percent of yellow tint in the new mixture:
percent of yellow tint =(amount of yellow tint / amount of mixture)*100
percent of yellow tint=(21 liters / 49 liters)100≈42.9%
Answer: The percent of yellow tint in the new mixture is 42.9%.
note: if this answer is not correct you can try it with 42.8%
