Answer:
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
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
