Answer:
Alice: 20 coins, Ben: 16 coins, and Carlos: 4 coins.
Step-by-step explanation:
We know that the dive results in 40 gold coins.
We know that:
Alice: $7,600 Ben: $5,900 Carlos: $1,400.
So they have $ 14900 in total.
Now we will divide that money by 40.
![x=\frac{14900}{40}\\\\x=372.5](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B14900%7D%7B40%7D%5C%5C%5C%5Cx%3D372.5)
So 1 gold coin costs $ 372.5. Now we will calculate how much they can get for the money they have.
![A=\frac{7600}{372.5}=20.4\\\\B=\frac{5900}{372.5}=15.8\\\\C=\frac{1400}{372.5}=3.75\\](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B7600%7D%7B372.5%7D%3D20.4%5C%5C%5C%5CB%3D%5Cfrac%7B5900%7D%7B372.5%7D%3D15.8%5C%5C%5C%5CC%3D%5Cfrac%7B1400%7D%7B372.5%7D%3D3.75%5C%5C)
We conclude that:
Alice: 20 coins, Ben: 16 coins, and Carlos: 4 coins.
Yes, (3, 2) is a solution to y = 2x - 4. (:
Answer:
7) (f+g)(x) = 4^x +5x -5
8) (f-g)(x) = 4^x +x +5
Step-by-step explanation:
7) add the two expressions.
(f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)
(f+g)(x) = 4^x +5x -5
__
8) subtract g(x) from f(x).
(f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5
(f-g)(x) = 4^x +x +5
