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) = 10 x - 30 , where x is the number of doors she knocks on during the week and E(x) is her earnings for the weeks in dollars.

Which of the following are reasonable interpretations of the y-intercept of Jessica's function?.

Check all that apply

A. Her expenses are $30 per week.

B. If she does not knock on any doors at all during the week she will loose $30.

C. She will loose $10 per week if she does not knock on any doors

D. She can earn $10 a week even if she does not knock on any doors.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
