Evaluate the expression 4x - y x + 2y if x = -1 and y = 2

Step-by-step explanation:

The given expressions are:

and

Now, we have to evaluate the expression using x=-1 and y=2, therefore by putting the values of  x=-1 and y=2 in both the given expressions, we get:

and

which are the required solutions.

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
