What the rate and unit rate to 9: 2 if you divide 18 and 4 by 2

The rate for 18:4 divided by 2:2 would be 9:2. This is because 18 divided by 2 is 9 and 4 divided by 2 is 2. The unit rate for 9:2 is 4.5:1. This is because you must divide 2 by 2 in order to get 1, and what you do to the second part you must do to the first part. 9 divided by 2 is 4.5.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
