Graph the line that represents a proportional relationship between d
dd and
t
tt with the property that an increase of
0.2
0.20, point, 2 units in
t
tt corresponds to an increase of
1.8
1.81, point, 8 units in
d
dd.
What is the unit rate of change of
d
dd with respect to
t
tt? (That is, a change of
1
11 unit in
t
tt will correspond to a change of how many units in
d
?
d?d, question mark)
The unit rate of change is

step-by-step explanation:

should you really be posting this isn't math boi.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
