Answer:
There are 14 dimes and 17 nickels.
Step-by-step explanation:
Let x be number of nickels and let y be number of dimes.
Given that the total is $2.25 and there are 31 coins, we know that:
Solving for x yields:
We then proceed by plugging that back into the previous equation:
--> Distribute
--> add y's together
--> subtract 1.55
--> divide by 0.05
Therefore, x must equal 17, which means you have 14 dimes and 17 nickels.
No. The circle can be composed of completely negative coordinates, but the radius is always a positive value. You can prove this by plugging any point and the center into the distance formula.
Answer:
100x+150y≤1200
y≤8-2x/3
slope = -2/3
