A quadratic with roots at 8 and 5 is f(x) = x^2 +12x + 20
In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.
x = -2 ----> add 2 to both sides
x + 2 = 0
We can do the same for the other zero.
x = -10 ----> add 10 to both sides
x + 10 = 0
Now that we have both of these, we can multiply these two things together. This will give us the function we need.
f(x) = (x + 2)(x + 10)
f(x) = x^2 + 10x + 2x + 20
f(x) = x^2 + 12x + 20

Step-by-step explanation:
Graphs are <em>equivalent</em> if they have the same structure, but not necessarily the same labeling.
The graph given is one big loop with one of the edges doubled. An equivalent graph is one that can be drawn as one big loop with one of the edges doubled. The attachment shows one way to draw such a graph.
Renaming the vertices of the attached graph to A, C, D, B (clockwise from lower left) will make it <em>equal</em> to the given graph.
Mrs. Guilhermina received hands of what she imagined this month, so she had to use the limit of her overdraft. What approximate amount will she pay, if she used R $ 5,500.00 for 1 month andto 14% in compound interest?
Amount owed = R$ 5.500,00 * (1+014./12)^1 = R$ 5.500.00*(1.011) = R$ 5.564,00
The ratio should be 1:6 seeing that every 1 cup of salad dressing there are 6 cups of vegetables
