The formula for how far a moving object travels in terms of the rate, or speed at which it moves, and the travel time, or how long it is moving, is d = rt, where d stands for distance, r stands for rate, and t stands for time. rearrange the quantities in this formula to give a new formula for travel time in terms of distance and rate of travel.
a. t=rd
b. t=d/r
c. t=r/d
d. t=d−r

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
