Type the correct answer in each box. use numerals instead of words. albert has $105 to spend on new basketball shoes. on his favorite shoe website, the prices for a pair of the shoes range from $80 to $180. the delivery fee is one-twentieth of the price of the basketball shoes. the total cost can be modeled by the function, f(c), where c represents the price of the basketball shoes. the domain of the function is [ , ]. before purchasing the shoes, albert remembered that his friend had to repay him an amount of money of $42. after receiving this amount, the domain for the function to represent the price of the basketball shoes that albert can afford is [ , ].

Step-by-step explanation:

Given that prices for a pair of shoes lie in the interval

[80,180] dollars.

Delivery fee 20% of price.  

i.e. delivery fee will be in the interval [4, 9]

(1/20th of price)

Total cost= price of shoedelivery cost

Hence f(c) = c+c/20 = 21c/20

The domain of this function would be c lying between 80 to 180

So domain =[80,180]

Amount to be repaid = 42 dollars

Once he received this amount, the price would be

105+42 =147

But since price range is only [21*80/20, 21*180/20]

=[84, 189]

Since now Albert has 147 dollars, he can afford is

[80,147]

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
