What is a rational number?A rational number is a number that can be written in the form of p/q where q is not equal to zero.
We have,
Sometimes True:
The sum of a rational number and an irrational number can be rational or irrational depending on the numbers chosen.
For example, 1 + √2 is irrational, but 1/2 + √2/2 is rational.
Always True:
The product of two rational numbers is always rational, as can be shown using the definition of rational numbers.
Always True:
The sum of an irrational number and a rational number is always irrational. This can be shown by contradiction.
Assume that the sum of an irrational number a and a rational number b is rational.
Then (a + b) - b is also rational, which implies that a = (a + b) - b is rational, contradicting the assumption that a is irrational.
Sometimes True:
The product of an irrational number and a rational number can be rational or irrational depending on the numbers chosen.
For example, √2 x 2 is irrational, but √2 x (1/√2) = 1 is rational.
Always True:
The sum of two rational numbers is always rational, as can be shown using the definition of rational numbers.

What is the slope of the line that passes through the points (0, -4)) and (-2, -1)
Answer:
Step-by-step explanation:
y = mx + b
m is the slope (what you want)
b is the y-intercept, which is the value of y when x = 0
Oh, right, we already have b, isn't that great!
Given point (0, -4), so b = -4
Point (-2, -1), where x = -2 and y = -1
-1 = -2m -4 (solve for m)
3 = -2m
m = -3/2
Check:
y = -3x/2 -4
y = -3(-2)/2 -4 -> should get y = -1
y = 3 -4 = -1
Yay, we have the answer!

C. 72
Step-by-step explanation:
So imagine every straight line you see equals to 180 degrees, so given one side of the angle...180 - 108 = 72
Answer:
72
Step-by-step explanation:
Because as we know the angle of this is 180 and we already have (108°) so we have to add 108° to one of the numbers till we get to (180°)

Solve for x in the diagram below.
X=?
Answer:
x = 40
Step-by-step explanation:
Answer:
x = 40°
Step-by-step explanation:
Because a line is 180°, the sum of all three angles would be 180°. So:
x + x + 100 = 180
2x + 100 = 180
2x = 80
x = 40
