Step-by-step explanation:

y = 28 - 2x

x = 1, y = 28 - 2(1) = 26

x = 3, y = 28 - 2(3) = 22

x = 4, y = 28 - 2(4) = 20

x = 5, y = 28 - 2(5) = 18

one number is equal to the square of another. find the numbers if both are positive and their sum is 1122
statuscvo [17]

Answer:

One number is 561

The other number is 23.6854

Step-by-step explanation:

x = y^2                One number = the square of another

x + y^2 = 1122     The sum of the two numbers is 1122

Substitute y^2 in for x on the second equation.

y^2 + y^2 = 1122    Combine like terms on the left

2y^2 = 1122            Divide by 2

y^2 = 1122/2

y^2 = 561                Take the square root of both sides.

y = 23.6854            

x = y^2

x = 561

y^2 = 561
