Expressions are mathematical statements represented with the variables
The value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5
<h3>How to determine the value of the variable</h3>
The expression is given as:

When x = -1, the expression becomes

Evaluate the exponent

When y = 5, the expression becomes

Evaluate the exponent
- 12/5
Hence, the value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

Step-by-step explanation:





Circumference = pi x diameter
So for this it is
36 = 3.14 x d (d = r x 2)
36 / 3.14 = 2r
11.46 = 2r
11.46 / 2 = r
5.73 = r
Answer:
If

then
0
