Step-by-step explanation:
(secx-tanx)(secx+tanx)
=sec^2-tan^2
=1
Answer:
3 x -3y = -9y
3 x -1 = -3
The factored expression is 3(-3y - 1)
Step-by-step explanation:
All you have to do is -9y / 3 = -3y and -3 / 3 = -1, then put those numbers in parentheses. All of that is multiplied by 3.
The reason is because if you distributed the 3 it would become:
3 * -3y + 3 * -1 = -9y - 3

Remember a rational number is a number that can be written with two whole numbers in a fraction, for example, 0.25 can be written as 1/4 notice how, both, the numerator and denominator are whole numbers AKA Integers(numbers that aren't decimals or fractions).
any number that can't be written by whole numbers in the numerator or denominator is an irrational number, things like Pi, Pi cannot be written by two whole numbers in the fraction.
50.652, is definitely rational because the fraction does not need decimal numbers in the numerator or denominator.
it can be written as:
or
notice how neither the numerator or denominators are decimals?
That is a strong negative correlation
strong - they look like a line
negative - the trend looks like a negative slope
