Question

the triangular region shows the number of possible ounces of platinum, x, and the number of possible ounces of silver, y, a jewelry maker can mix together to make a certain piece of jewelry. which combination of platinum and silver can the jewelry maker use? 16 oz of platinum and 30 oz of silver 12 oz of platinum and 20 oz of silver 25 oz of platinum and 20 oz of silver 10 oz of platinum and 10 oz of silver

Explanation:

Step1: Identify the coordinates on the graph.

The x - axis represents ounces of platinum ($x$) and the y - axis represents ounces of silver ($y$). We need to check which point $(x,y)$ lies within the triangular shaded region.

Step2: Check option A.

For the point $(16,30)$, when $x = 16$ and $y=30$, we can see from the graph that this point lies outside the triangular region.

Step3: Check option B.

For the point $(12,20)$, when $x = 12$ and $y = 20$, this point lies within the triangular shaded region.

Step4: Check option C.

For the point $(25,20)$, when $x=25$ and $y = 20$, this point lies outside the triangular region.

Step5: Check option D.

For the point $(10,10)$, when $x = 10$ and $y=10$, this point lies outside the triangular region.

Answer:

12 oz of platinum and 20 oz of silver
