Answer:
Fourth option.
Sixth option.
Step-by-step explanation:
We know that:
- Any number you can find on the number line, is a Real number.
- Integers contains positive numbers, negative numbers and zero. Every Integer is a Rational number.
- A Rational number is that number that can be written in the following form:
Where "a" and "b" are integers ().
- An Irrational number cannot be written as a simple fraction.
- A Whole number is any of the numbers {}. Every Whole number is a Rational number.
- Natural numbers contain the set of positive integers{} or to the set of nonnegative integers {
}, Every Natural number is a Rational number.
Based on this, since is in the form
where
and
, it is a Rational Number and therefore a Real number.
Answer:
Step-by-step explanation:
We can model this function using the equation of a line:
Where a is the slope of the line and b is the y-intercept.
To find the values of a and b, we can use the two points given:
(-9, -3):
(-12, 4):
If we subtract the second equation from the first one, we have:
Then, finding the value of b, we have:
So the equation is:
Answer:
belongs to the line
. Please see attachment below to know the graph of the line.
Step-by-step explanation:
From Analytical Geometry we know that a line is represented by this formula:
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- y-Intercept, dimensionless.
If we know that ,
and
, then we clear slope and solve the resulting expression:
Then, we conclude that point belongs to the line
, whose graph is presented below.
Therefore 1364.69 should be rounded up to 1000.
