Answer:
-3
Step-by-step explanation:
2/3 = 0.66
0.66 x -3 = 1.98
If you're allowed to round up, the answer is -3.
The answer is y=3/2x+3
to figure it out:
1. you need to first find the slope of the two points.
3-0/0-(-2)
2. then put them into slope intercept form: y=mx+b. m being your slope and b being your y-intercept.
Answer:
(a) 349.34
(b) 77.63 km/h
Step-by-step explanation:
Distance you covered before it rain S = 180 km
Speed v = 95/km
Time taken to cover 180 km =
=
= 1.89473 hrs.
Total time to cover the distance between school to home T = 4.5 hrs.
Remaining time t = T - t
= 4.5 - 1.89473
= 2.60527 h.
Velocity after travel 180 km. v' = 65 km/h
Distance traveled in this velocity S' = v'(t)
= 2.60527 × 65
= 169.34 km
(a) distance of hometown from school = 169.34 + 180 = 349.34 km.
(b) Your average speed V =
=
= 77.63 km/h
