The points (1,r) and (0,-6) fall on a line with a slope of
-4. what is the value of r?
r=

Hey!

--------------------------------------------------

Steps To Solve:

Slope Formula:

~Substitute with the coordinates given

~Simplify

Now we can solve for r.

~Simplify the equation.

r + 6 = -4

~Subtract 6 to both sides

r + 6 - 6 = -4 - 6

~Simplify

r = -10

--------------------------------------------------

Hence, the value of r is

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
