Suppose you have a clothes dryer that uses 4000 watts of power and you run it for an average of 1 hour each day. If you pay the utility company 14¢ per kilowatt-hour of elec- tricity, what is the average daily cost to run your dryer? How much would you save in a year if you replace it with a more efficient model that uses only 2000 watts?

equal to

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

50- 250 is correct i did that one too

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
