1 Select the correct answer.
If x is a number that is 7 more than y, how do you express x as a function of y?
A.
X = Ry) = 7 + x
O B.
x = ) = 7 + y
O C.
y = f(x) = 7x
OD. y = f(x) = y - 7
O E. y = fx) = 7+ y

answer: i can’t tell you that

step-by-step explanation:

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
