Determine whether the graphs of y=6x+4 and y=1/6x are perpendicular.

Step-by-step explanation:

first we find the slopes and compare them

y = 6x + 4slope here is 6

y = 1/6xslope here is 1/6

perpendicular lines have negative reciprocal slopes.

These equations are not perpendicular.

look at y = 6x + 4slope is 6a perpendicular line will have a negative reciprocal slope...all that means is flip the slope and change the signso a perpendicular line will have a slope of :  6 or 6/1flip the slope1/6change the sign...-1/6so a perpendicular line to y = 6x + 4 would have to have a slope of -1/6.

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
