Answer:

Step-by-step explanation:

rearrange this equation into slope-intercept form(y=mx+b)

2y=-6-x

y=-3-x/2

y=-1/2*x-3

m is the slope

b is the y-int

slope=1/2

y-int= -3

Answer:

43.82 mph

266.67 feet

Step-by-step explanation:

Given :

S = √30fl

S = speed of car

f = drag Coefficient

l = Length of skid mark

If f = 0.8 ; l = 80 feets

s = √30fl

s = √(30*0.8*80)

s = √1920

s = 43.817

s = 43.82 mph

B.)

s = 80 mph

f = 0.8

s = √30fl

80 = √30*0.8*l

80 = √24l

Square both sides

80² = 24l

6400 = 24l

l = 6400/24

l = 266.67 feets
