4y+18=-8y+17 what’s the answering

y = -1/12

Step-by-step explanation:

4y+18=-8y+17

Add 8y to each side to get the variable on one side

4y+8y+18=-8y+8y+17

12y +18 = 17

Subtract 18 from each side to get the constant on the other side

12y +18-18 = 17-18

12y =-1

Divide each side by 12 to isolate the variable

12y/12 =-1/12

y = -1/12

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)
