Answer:
The answer is given below
Step-by-step explanation:
The question is not complete, because the function for the profit is not given but I can show you how to calculate this.
Since Mr. Wilson has a bakery and a juice bar, his total profit earned in t months would be the sum of profit from the bakery with the profit from the juice bar within t months.
Let us assume that the profit from the bakery in t months is given by:
B(t) = 2t³
while the profit from the juice bar in t months is given by:
J(t) = 
Therefore the total profit is given by:
P(t) = B(t) - J(t) =

Step-by-step explanation:
De acuerdo a la información proporcionada puedes plantear las siguientes ecuaciones:
x+y=120 (1)
2x-0,5y=80 (2)
x es el número de preguntas correctas
y es el numero de preguntas incorrectas
Primero debes despejar "x" en (1):
x=120-y (3)
Después, debes reemplazar (3) en (2):
2(120-y)-0,5y=80
240-2y-0,5y=80
240-80=2,5y
160=2,5y
y=160/2,5
y=64
Ahora puedes reemplazar el valor de "y" en (3) para encontrar el valor de "x":
x=120-y
x=120-64
x=56
De acuerdo a esto, la respuesta es que el postulante respondió mal 64 preguntas.
Answer:
1/5
Step-by-step explanation:
2/5 - 1/5
2-1 = 1
5 Stays the same so your answer is 1/5
Answer/Step-by-step explanation:
The problem replaces the x with the appropriate input. It is asking for you to find the correct output (y). Looking at the graph, when the point hits -1 on the x value, the value for y is 3. So, the correct output is 3.
