Question

7|-x|-4|3y-3,4 при x -1,1 и у y 0,8

Answer 1

7*1,1-4*|3*0,8-3,4|=7,7-4*|2,4-3,4|=7,7-4*1=7,7-4=3,7

Answer 2

To solve this expression for $x = -1, 1$ and $y = 0, 8$, we substitute these values into the expression and simplify:

For $x = -1$ and $y = 0$:

$7|-(-1)|-4|3(0)-3,4$

Simplify:

$7|1|-4|0-3,4$

$7-3,4 = 3,6$

For $x = -1$ and $y = 8$:

$7|-(-1)|-4|3(8)-3,4$

Simplify:

$7|1|-4|24-3,4$

$7-92,4 = -85,4$

For $x = 1$ and $y = 0$:

$7|-(1)|-4|3(0)-3,4$

Simplify:

$7|1|-4|0-3,4$

$7-3,4 = 3,6$

For $x = 1$ and $y = 8$:

$7|-(1)|-4|3(8)-3,4$

Simplify:

$7|1|-4|24-3,4$

$7-92,4 = -85,4$

So, the results for the given values are:

1. $x = -1$, $y = 0$ → $3,6$
2. $x = -1$, $y = 8$ → $-85,4$
3. $x = 1$, $y = 0$ → $3,6$
4. $x = 1$, $y = 8$ → $-85,4$
