Find all pairs of numbers that satisfy these two conditions: their sum is 20 and the sum of their squares is less than 362.

See the explanation

Step-by-step explanation:

Let

x and y the numbers

we know that

-----> equation A

-----> inequality B

using a graphing tool

The numbers that satisfy the two conditions are all the real numbers that lie on the line in the domain for x ----> (1,19)

see the attached figure

Example

(2,18),(3,17).(3.2,16.8). (3.25,16.75)....
