Question

X=-5.2,y=-4,8 найдите значение выражения x + y, найдите значение выражения |x + y| найдите значение выражения |x| + |y|​

Answer 1

Ответ:

Пошаговое объяснение

x+y = -5,2+(-4,8) = -5,2-4,8= -10

l x+y l = l -5,2+(-4,8) l = l -5,2-4,8 l =l -10 l = 10

lxl+lyl= l-5,2l+l-4,8l = 5,2+4,8 = 10

Answer 2

To find the values of the expressions, let's perform the calculations step by step:

1. x + y: x = -5.2 y = -4.8 x + y = -5.2 + (-4.8) = -10

2. |x + y| (the absolute value of x + y): |x + y| = |-10| = 10

3. |x| + |y| (the sum of the absolute values of x and y): |x| = |-5.2| = 5.2 |y| = |-4.8| = 4.8 |x| + |y| = 5.2 + 4.8 = 10

So, the values of the expressions are:

1. x + y = -10
2. |x + y| = 10
3. |x| + |y| = 10
