<span>90 m/s; it represents the average speed of the object between 2 seconds and 4 seconds, and here's why:
the main formula is v= D / Dt, D=Dfinal - Dinitial
Dt= tfinal - tinitial
so between t=2 and t= 4, V = 240-60/ 4-2= 90m/s

(x+y) / 2 =7
multiply both sides by 2
x+y=14
3x=.5y
divide both sides by .5
6x=y
plug 6x in for y
x+(6x)=14
simplify
7x=14
divide both sides by 7
x=2
Answer:
y=9
Step-by-step explanation:
A horizontal line has a constant y value
It goes through the point (1,9) so the y value is 9
y=9
