Line l is perpendicular to a line with slope -5 and passes through (2, -2). find an equation of line l and write the answer in the slope - intercept form.

y=1x +8

5

Step-by-step explanation:

y-y1 = m(x-x1)

y+2 = -5(x-2)

y+2 = -5x + 10

y = -5x +8

Now to find line L we have to change the slope because it is perpendicular

y= 1x +8 (The slope is one fifth, but idk

5. to put it, I'm sorry)

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)

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
