Answer:
The final answers are x = 1 OR x = -3.
Step-by-step explanation:
Given the equation is x^2 -3 = -2x
Rewriting it in quadratic form as:- x^2 +2x -3 = 0.
a = 1, b = 2, c = -3.
Using Quadratic formula as follows:- x = ( -b ± √(b² -4ac) ) / (2a)
x = ( -2 ± √(4 -4*1*-3) ) / (2*1)
x = ( -2 ± √(4 +12) ) / (2)
x = ( -2 ± √(16) ) / (2)
x = ( -2 ± 4 ) / (2)
x = (-2+4) / (2) OR x = (-2-4) / (2)
x = 2/2 OR x = -6/2
x = 1 OR x = -3
Hence, final answers are x = 1 OR x = -3.
Answer:
The greater percent of cell phone ownership in Japan than the U.S was <u>13.7%</u>.
Step-by-step explanation:
Given:
About 543 out of every 1,000 people in United States owned a cell phone in 2003.
In japan,the are was 68 for every 100 people.
Now, to find the greater percent of cell phone ownership in Japan than the U.S.
So, to get the percent of people owned cell phone in United States:



Now, to get the percent of people owned cell phone in Japan:

So, to get the percent greater of cell phone ownership in Japan than the U.S we subtract the percent of people owned cell phone in United States from the percent of people owned cell phone in Japan:

Therefore, the greater percent of cell phone ownership in Japan than the U.S was 13.7%.
