Answer find the the solution of this system of equations -6y=50-4x 5x-6y=-49

x = 0.11, y = 8.26  to the nearest hundredth.

Step-by-step explanation:

6y=50-4x (1)

5x-6y=-49

6y = 49+5x(2)

Subtract (1) - (2):

0 = 1 - 9x

x =  1/9 or 0.11

Substitute for x in  equation (1):

6y = 50 - 4(1/9)

6y =  49.556

y =  8.26

y=mx+b is the final answer!   : )

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)
