Answer:
Janet has coins worth 252.5, 101, and 50.5.
Step-by-step explanation:
Let us call the three coins , and
.
The first coin is 5 times another coin<em> (let's say </em>
); therefore,
,
and the third coin is 2 times the value of another coin<em> (it's coin </em><em>):</em>
<em /><em>.</em>
The total worth of all coins is 404; therefore,
or
with the value of in hand, we find
and
:
and for

Answer:
(0,0)
Step-by-step explanation:
Let's think about how the graph of this would look.
We know that y will be , meaning that if x was 0, y would be 0.
If x was 1, y would be 1
If x was 2, y would be 4.
Now let's think about negative numbers.
If x was -1, y would be 1 (since
If x was -2, y would be 4 (since ).
This means that our graph would turn at the point where x and y are equal (excluding 1,1)
This is 0,0.
So 0,0 is the turning point of this graph.
Hope this helped!
