1 km = 1000 meters and 1 hour = 3600 seconds.
9x1000= 9000
9000/3600= 2.5
Your answer would be 2.5 meters per second.
Answer:
20y = -5x + 10
y = -1/4x + 1/2
y - 3 = -1/4(x - 8)
y - 3 = -1/4x + 2
y = -1/4x + 5
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Given
A delivery service charge 
for each delivery
and an additional 
for each mile traveled
Suppose, x miles are covered
The charge is given by
Therefore, driver traveled 6 miles for delivery
<span>First we have to determine the slope of each lines by transforming to the slope-intercept form:
y=(3x-7/)4; m2= ¾y=(12x+6)/5, m3 = 12/5
The formula to be used in the proceeding steps is a=tan^-1(m1-m2)/1+m1m2=tan^-1(m1-m2)/1+m1m2
substituting, a=tan^-1(m1-3/4)/1+3m1/4=tan^-1(m1-12/5)1+12m1/5) =>(4m1-3)/(4+3m1)=(5m1-12)/(5+12m1)m1 = -1applying this slope
y -y1 = m(x-x1)
when y1 = 5 and x1 = 4 then,
y - 5 = -1(x-4)
y = -x +4+ 5 ; y = -x +9</span>
? is there any more context to the question?
