Answer:
-2/5
Step-by-step explanation:
We can find the slope of a line by using
m = (y2-y1)/ (x2-x1)
= (6-4)/(41-46)
= 2/-5
= -2/5
S=d/t
45=29/t
t=45/29
convert to min
t=45/29 *60=38.66min
The answer is -4k^2 - 21k - 20! so sorry if I’m wrong but it’s the answer I got :>
The word that describes it is congruent
