Answer:
The correct answer is A.; C.; E.
Step-by-step explanation:
A. Negative integers are rational numbers because all integers are rational numbers, i.e. integers are a subset of rational numbers, making the statement correct.
B. Mixed numbers are rational numbers because they can be written in the form of a simple fraction and thus the statement B is wrong.
C. Decimal numbers that terminate, like 0.125, are rational numbers is true as they can be written as a simple fraction making the statement true.
D. Decimal numbers that go on forever with repeating patterns, like 4.272727..... are irrational numbers is false as they can also be represented by a simple function making them rationals.
E. Decimal numbers that go on forever with no repeating patterns are irrational numbers as they can never be written as a simple fraction making the statement E true.
Answer:
The equation of the quadratic in standard form is:
Step-by-step explanation:
Since they give us the information about where the vertex of the parabola is located, and one extra points where it passes through, we can use the general form of a quadratic in vertex form:
where 
is the location of the vertex (in our case the point (-2,6).
Therefore the equation above becomes:
Now,we can use the fact that the point (-4,-2) is also a point of the graph, to find the value of the parameter 
:
Then, the equation of the quadratic with such characteristics becomes:
which is the equation of the quadratic in standard form.
since the thousands place is a 3 which is lower than a 5
it would be rounded to 20,000
