If it is not contained in a fraction write it as one over the variable with a positive exponent
ex. 2^-1 = 1/2. 3^-2 = 1/3² = 1/9

if it is in the denominator of a fraction move it to the numerator and make it positive
ex. 1/4^-1 = 4. 2/3^-2 = 2*3² = 18

if it is in the numerator...you get the picture
ex 6^-2/3 = 1/3*6² = 1/108

hope that helps

SVEN [57.7K]

The inequality that can be used to represents all possible combinations of x, the number of hamburgers and y, the number of briskets that will be cooked is 5y + 0.25x ≤ 150

Given:

pounds of brisket = 5 lb

Pounds of hamburger = 0.25 lb

Total pounds of briskets and hamburgers = no more than 150 lb

number of hamburgers = x

number of briskets = y

No more than in inequality = (≤)

The inequality:

5y + 0.25x ≤ 150

Therefore, inequality that can be used to represents all possible combinations of x, the number of hamburgers and y, the number of briskets that will be cooked is 5y + 0.25x ≤ 150

You only need two numbers to do that.
The numbers are  16  and  -3 .

           16  -  3  =  13

         (16) x (-3)  =  -48
