Teresa is walking. D(t), given below, is her distance in kilometers from Glenn City after t hours of walking. D(t) = 10.4 - 4t

a) Which statement best describes D^-1(x)?
a. The amount of time she has walked (in hours) when she is x kilometers from Glenn City
b. The reciprocal of her distance from Glenn City (In Kilometers) after walking x hours.
c. Her distance from Glenn City (in kilometers) after she has walked x hours.
d. The ratio of the amount of time she has walked (in hours) to her distance from Glen City (in kilometers) x.

b) D^-1(x) =

c) D^-1(5.2) =

A, (x - 10.4) / -4, -1.3

Step-by-step explanation:

(a)

D(t) = Teresa's distance in kilometers from Glenn City after t hours of walking. The inverse of this would be the time she has walked about x kilometers.

(b)

D(t) = 10.4 - 4t

Change t to x --> y = 10.4 - 4x

Switch x and y --> x = 10.4 - 4y    

Solve for y:

D^-1(x) = x - 10.4 = -4y

D^-1(x) = (x-10.4)/-4

(c)

Insert 5.2 where x is:

(5.2 - 10.4) / 4 = -1.3

i will pick c put check it over to be sure

step-by-step explanation:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
