Answer:
12 sapphires
Step-by-step explanation:
Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.
# of Sapphires: x
# of Rubies:17-x
A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.
We also know the total amount of money is 100 coins, so
5*x+8*(17-x)=100
5x+136-8x=100
-3x=-36
x=12
Remember:
# of Sapphires: x
# of Rubies:17-x
...so Lara found 12 sapphires and 17-12=5 rubies.
We are given function: f(x) = 12x+3.
Generally we start x from 0 and we can take any number for x to get some real number of f(x).
Therefore, domain of the function start from 0.
And we can take any number 0 or greater than 0 to get some value of f(x).
So, we can say that domain of the function is " All real numbers greater than or equal to 0".
<h3>Therefore, Prectical domain : All real numbers greater than or equal to 0.</h3>
