That's an increase of 30,000,000 people in one year, a slope of 30 million and a good year for the internet.
If t is the year, and p is number of internet users,
p = 30000000(t - 1997) + 60000000
Answer: p = 30000000(t - 1997) + 60000000
As for linear versus exponential, one year of data can't really distinguish.
Answer:
1) g ≥ 17
2) g > -10
3) g > -1
Step-by-step explanation:
1) 7 (g-19) ≥ -14 divide both sides by 7
g - 19 ≥ -2 add 19 to both sides
∴ g ≥ 17
=======================================
2) 3(7g+17) > -19 + 14g
21g + 51 > -19 + 14g
21g - 14g> -19 - 51
7g > -70
g > -10
========================================
6(-6g+6) > -2(19g-17)
-36g + 36 > -38g + 34
-36g + 38g > 34 - 36
2g > -2
g > -1
========================================
