Question

3|-y|+7|4+x|при x=7и y=-1​

Answer 1

Ответ:

3*/-(-1)/+7*/4+7/=3*/1/+7*/11/=3*1+7*11=3+77=80

Answer 2

To evaluate the expression 3|-y| + 7|4+x| when x = 7 and y = -1, we substitute the given values into the expression:

3|-(-1)| + 7|4+7|

First, let's simplify the absolute values:

3|1| + 7|11|

The absolute value of 1 is 1, and the absolute value of 11 is 11. Substituting these values:

3(1) + 7(11)

Now, we can perform the multiplications:

3 + 77

Finally, we add the numbers:

80

Therefore, when x = 7 and y = -1, the value of the expression 3|-y| + 7|4+x| is 80.
