Answer:
<em>(12, 2)</em> is the original point on the graph of 
.
Step-by-step explanation:
<u>Given:</u>
has a point <em>(3, 6)</em> on its graph.
<u>To find:</u>
Original point on graph = ?.
<u>Solution:</u>
We are given that The point (3, 6) is on the graph of
If we put x = 3 and y = 6 in , it will satisfy the equation.
Let us the put the values and observe:
Now, let us compare the above with the following:
we get y = 2 and x = 12
So, the original point on graph of is <em>(12, 2).</em>
Answer:
- 12.5 ounces of 12% alloy
- 37.5 ounces of 24% alloy
Step-by-step explanation:
Let x represent the amount (in ounces) of 24% alloy in the mix. Then the amount of 12% alloy is (50 -x). The amount of silver in the mix is ...
24%·x + 12%·(50 -x) = 21%·50
12x = 450 . . . . . . simplify, multiply by 100 (to eliminate %), and subtract 600
x = 37.5 . . . . . . . divide by 12
The jeweler needs to mix 37.5 ounces of 24% silver alloy with 12.5 ounces of 12% silver alloy to make 50 ounces of 21% silver alloy.
Answer:x = -12
