Answer:
-3.25
Step-by-step explanation:
Simply plug in a -1 for the x and a 4 for the y, and then use a calculator
The value of the expression 13x^-3y^-1, when x is -1 and y is 4, is -3.25.
The given expression is 13x-3y-1 and the provided values are x = -1, y = 4. Plugging these values in, the expression is simplified to:
13*(-1)-3*(4)-1
This simplifies to:
13*(1/-1)*1/4 = -13/4 = -3.25
So, the result is -3.25.
