Jessica is selling books during the summer to earn money for college. she
earns a commission on each sale but has to pay for her own expenses.
after a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
she writes the equation of the function like this: e(x) = 7x - 25, where x is the
number of doors she knocks on during the week and e(x) is her earnings for
the week in dollars.
which of the following are reasonable interpretations of the y-intercept of
jessica's function?
check all that apply.

#2, her earnings will increase by $20 for each door knocked.

Step-by-step explanation:

Since the only variable used to determine earnings is the number of doors knocked, you can eliminate options 1 and 3 as they are based on the number of books sold, which is not a part of the equation.

That leaves the only options being the increase of $20 or $50 for each door knocked. As the x value us multiplied by 20, the correct answer is #2, her earnings will increase by $20 for each door knocked.

You can also check this by plugging in values:

Assume 10 doors are knocked:

E(10) = 20(10)-50 = 200-50 = 150

Assume 11 doors (1 more door) is knocked:

E(11) = 20(11)-50 = 220-50 = 170

The increase from 1 door is $20.

step-by-step explanation:

step-by-step explanation: the declaration of the rights of man and of the citizen (french: déclaration des droits de l'homme et du citoyen de 1789), set by france's national constituent assembly in 1789, is a human civil rights document from the french revolution.[1]

the declaration was drafted by the abbé sieyès and the marquis de lafayette, in consultation with thomas jefferson.[2] influenced by the doctrine of "natural right", the rights of man are held to be universal: valid at all times and in every place, pertaining to human nature itself. it became the basis for a nation of free individuals protected equally by the law. it is included in the beginning of the constitutions of both the fourth french republic (1946) and fifth republic (1958) and is still current. inspired by the enlightenment philosophers, the declaration was a core statement of the values of the french revolution and had a major impact on the development of freedom and democracy in europe and worldwide.[3]

the 1789 declaration, together with the 1215 magna carta, the 1689 english bill of rights (1689), the 1776 united states declaration of independence, and the 1789 united states bill of rights, inspired in large part the 1948 united nations universal declaration of human rights
