1. Tis inversely proportional to m. If T = 6 when m = 2, find
a. the value of T when m = 4.
b. the value of m when T = 4.8.
2. y is inversely proportional to the cube of x. If y = 2, find
a. an equation of y in terms of x,
b. y when x = 1
c. x when y = .

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
