1/2 - y (6y - 8)
1/2 -6y2 - 8y
the answer is A
If you do 81 x 9 which equals 729. If you want to check, you do 729 divided by 9 and you get 81.
Responder:
10 (2ny- (x-y))
Explicación paso a paso:
Dada la expresión 10ny-10x + 10ny + 10y, para simplificar la expresión, se deben seguir los siguientes pasos;
Paso 1; Separa la expresión en términos similares
= 10ny-10x + 10ny + 10y
= (10ny + 10ny) - (10x + 10y)
Paso 2: Factoriza los valores comunes en ambos paréntesis
10ny (1 + 1) - 10 (x-y)
= 10ny (2) - 10 (x-y)
= 20ny - 10 (x-y)
Factoriza nuestro valor común en ambos términos:
= 10 (2ny- (x-y))
Answer:
x₁ = 20 x₂ = 0
z (min) = 20
Step-by-step explanation:
According to the problem statement:
Let´s call
Objective quiz = x₁ Recall quiz = x₂
First constraint
Quantity of quizzes at least 15
x₁ + x₂ ≥ 15
Second constraint:
Preparation time at least 300 minutes, then
15*x₁ + 30*x₂ ≥ 300
Third constraint
Average score at least 85 points
7*x₁ + 5*x₂ ≥ 85
General constraint x₁ ≥ 0 x₂ ≥ 0
Objective function z is:
z = 1* x₁ + 1,5*x₂ to minimize
The model:
z = x₁ + 1,5x₂ to minimize
Subject to
x₁ + x₂ ≥ 15
15*x₁ + 30*x₂ ≥ 300
7*x₁ + 5*x₂ ≥ 85
Using Atozmax (online solver) we find
x₁ = 20 x₂ = 0
z (min) = 20
