nearly 68 percent of American homes were electrified. But, if you don't count farms, about 85 percent of Americans had electricity by the end of the 1920s.
And there's the rub. Rural communities, including farms, were far slower in adopting electricity than the rest of the country. Of the roughly 6.3 million American farms in 1922, only about 3% had electricity. It wasn't until 1935 that the U.S. government addressed this huge rural vs urban electric divide with the formation of the Rural Electrification Administration.
6 shirts and 8 sweater cost $152
or
5 shirts and 7 sweaters cost $132
$152 - $132 = $ 20 that was taken away from both things being gone (1 sweater and one shirt)
The answer could be that a shirt costs $10 and a sweater cost $10 or it could mean the shirt cost $9 and the sweater costs $11 or it could swap and be the shirt costs $11 and the sweater costs $9. Or the shirt costs $1 and the sweater costs $19 or A shirt costs $3.50 and the Sweater costs $16.50.
The product is: 25x^2-5xy-6y^2
The average rate of change obtained from the ratio of change in y to the change in x is 27
The average rate of change can be obtained using the relation :
Rate of change = (y2 - y1) ÷ (x2 - x1)
at; x1 = -3
y1 can be calculated from the function ;
y1= 3(-3³)-1
y1=-82
At ; x2 = 3
y2 can be calculated from the function ;
y2 = 3(3³)-1
y2=80
The rate of change can be calculated thus : (y2 - y1) ÷ (x2 - x1)
[80-(-82)]/[3-(-6])
162/6
27
