What would be the range for {(-6, 4), (5, -1), (0, 3), (-2, 4)}

{4, -1, 3}

Explanation: The range is the set of all y-coordinates for our ordered pairs.

So the range for this relation is 4, -1, 3, 4.

Notice that we have two 4's as y-coordinates

but we only need to mention the 4 once.

So our range is {4, -1, 3}.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
