Sketch and shade the region in the xy-plane defined by the equation or inequalities. |x| < 7 and |y| < 2

Here we have:

IxI < 7

This also can be written as:

-7 < x < 7

and:

IyI < 2.

As above, we can write this as:

-2 < y < 2.

Then the graph of this region will be a rectangular area, where the perimeter is a dashed line (because here we use the strictly smaller or strictly larger symbols)

Such that the vertical component goes from -2 to 2, and the horizontal component goes from -7 to 7.

The area would be the area inside that rectangle, where i did not shade it so it is easier to read.

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !
