At the curb a ramp is 11 inches off the ground. the other end of the ram rests on the street 55 inches from the curb write a linear equation in slope intercept form that relates the height y of the ramp to he distance x from the curb

The linear equation in slope intercept form that relates the height y of the ramp to he distance x from the curb is:

If we model this equation on a coordinate plane we see that the ramp passes through the point (0,11) and (55,0)

where the horizontal axis i.e. the x-axis represent the distance of the ramp from the curb and the vertical axis represent the  height y of the ramp.

We know that the ramp satisfies a linear relationship.

Hence, the slope is constant between two points.

i.e. the slope of a line passing through (a,b) and (c,d) is calculated by:

Also, the slope intercept of a line is given by:

y=mx+b

where m is the slope and b is the y-intercept.

From the given problem we have slope as:

Also, y-intercept is: b=11

( Since the y-intercept is the value where x=0 )

          The equation  is given as:

1. minimum

2. 6400

3. eight

hope this !

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
