Step-by-step explanation:
Answer:
Transversal
Step-by-step explanation:
Answer:
n=10
Step-by-step explanation:
Velocity, in km/hr is the x-axis.
Breaking distance "s" in meters is on the y-axis.
Each curved line represents the different road conditions.
for (a.) find the y-coordinate for each
Dry, curve A. follow the 50km/hr up to the curve and see it corresponds to about 30 m
Wet road, curve B. follow the 50km/hr mark up to see it corresponds to 80 m
Icey, curve T is 140 m
for (b.) they give you the breaking distance on the y-axis to find the corresponding speeds for each road condition. Follow the 60 m mark across to find each x-coordinate,.
Dry curve A, 70 km/hr
Wet curve B, about 45 km/hr
Icey curve T, 30 km/hr
5(2x-3)+7
distribute the 5 to the 2x and -3
10x-15+ 7
combine like terms -15+7
10x-8
