Question

{x+y=14​

Answer 1

X + y = 14, y = 14 - x.
x² + y² = 100,
x² + (14 - x)² = 100,
x² + x² - 28•x + 14² = 100,
2 •x² - 28•x + 96 = 0,
x² - 14•x + 48 = 0.
Дискриминант:D = 14² - 4•48 = 196 - 192 = 4.
x1 = (14 - 2):2 = 6, x2 = (14 + 2):2 = 8
y1 = 14 - x1 = 14 - 6 = 8,
y2 = 14 - x2 = 14 - 8 = 6.

Answer 2

The equation you've provided is:

x + y = 14

This is a linear equation in two variables, x and y. It represents a straight line on a Cartesian coordinate system. To graph this equation, you can rearrange it in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

To do that, we can isolate y:

x + y = 14

Subtract x from both sides:

y = 14 - x

Now it's in slope-intercept form, and you can see that the slope (m) is -1 (the coefficient of x), and the y-intercept (b) is 14. This means the line crosses the y-axis at the point (0, 14), and it has a slope of -1, which means it goes down 1 unit in the y-direction for every 1 unit to the right in the x-direction.

So, you can graph this line by plotting the point (0, 14) on the y-axis and then using the slope to find additional points. For example, if you move 1 unit to the right from (0, 14), you would go down 1 unit to (1, 13), and so on. Connect these points, and you have the graph of the line x + y = 14.
