Vlad spent 20 minutes on his hisson our homework and then completely solved x math problems that each took 2 minutes to complete . what is the equation that can be used to find the value of y, the total time that vlad spent on his homework and what are the constraints on the values of x and y

The equation that will be used to find y, the total time spent on homework is given by:

y=20+2x  , where both x and y are integers.

with the constraints as:

x ≥ 0

and y ≥ 20

Step-by-step explanation:

Vlad spent 20 minutes on his Hisson our homework and then completely solved x math problems that each took 2 minutes to complete .

Hence, the time taken to solve maths problmem is: 2x minutes.

Let y represent he total time that Vlad spent on his homework.

Hence, the equation that is can be used to find the value of y is:

y=20+2x.

where x is any integer greater than or equal to 0.

i.e. x ≥0

and y will be an integer greater than or equal to 20.

i.e. y ≥ 20

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)
