Los nutriólogos recomiendan que una persona debe tomar en promedio 2.5 litros de agua en un día, para que esté bien hidratada. ¿cuántos litros de agua debe tomar una persona en un mes para que cumpla con una buena hidratación? (considera un mes igual a 30 días) formule una expresión algebraica para determinar el total de litros de agua que debe tomar una persona dado un determinado número de días

the question in English

Nutritionists recommend that a person should drink an average of 2.5 liters of water in a day, to be well hydrated. How many liters of water should a person drink in a month to comply with a good hydration (Consider a month equal to 30 days) Formulate an algebraic expression to determine the total liters of water that a person should drink a given number of days.

Let

x-------> the number of days

y------> the total liters of water

we know that

 ------> algebraic expression to determine the total liters of water that a person should drink a given number of days

For x=30 days (1 month)

substitute in the formula

therefore

the answer is

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
