Question

5х-3|у+2| при х=-2,у=-4

Answer 1

5(-2)-3|-4+2|= -7|6|

Answer 2

5x-3/y ·2/
5x-2x/y/
5·/+2/-4/
-5+2/-4/
-5+11=6

Answer 3

To evaluate the expression 5x - 3|y + 2| when x = -2 and y = -4, we substitute the given values into the expression and perform the necessary calculations.

Substituting x = -2 and y = -4 into the expression, we have:

5(-2) - 3|-4 + 2|

Simplifying further:

-10 - 3|-4 + 2|

|-4 + 2| is equal to |-2|, which is 2. Therefore, we have:

-10 - 3(2)

Performing the multiplication:

-10 - 6

Finally, subtracting:

-16

So, when x = -2 and y = -4, the expression 5x - 3|y + 2| evaluates to -16.
