∡rst is a right angle. if rs has a slope of 3, what must be the slope of st?

Answers

Answer 1

Answer:

Answer:

The slope of st is -1/3

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

$m1*m2=-1$

we have

$m1=3$

substitute and solve for m2

$(3)*m2=-1$

$m2=-(1)/(3)$

therefore

The slope of st is -1/3

Is a negative decimal always sometimes or never equal to a positive decimal

Answers

It would never be equal because negative decimals and positive decimals are on either ends of the number line, negative is lass than 0 and positive is greater than 0. So they cannot be equal in any case.

Never. Negative numbers by definition are separate class from positive numbers, so negative decimals are never equal to positive numbers.
