Work out 4/9 + 2/9 and simplify where possible (it isnt 6/9)

2/3

Step-by-step explanation:

4/9+2/9=6/9

divide each number by 3 and that with give you your answer 2/3.

6÷3=2 and 9÷3=3

Adding fractions with same denominator

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
