Answer:
Step-by-step explanation:
2004 - 1995 = 9 years
793 - 54 = 739 new sites
739 / 9 = 82.1111111111
approx 82 websites per year change.. ( delta is change )
C & D
Step-by-step explanation:
One evident common factor between 60, 90, & 20 is 10 because all these numbers end in a 0; Therefore one way to factor the equation 60y - 90 - 20x is;
10 (6y – 9 – 2x)
5 is also a common factor between the numbers 60, 90, & 20
60/5 = 12; 90/5 = 18; 20/5 = 4
Therefore 60y - 90 - 20x is also equal to;
5 (12y – 18 – 4x)
Answer:
exponential
Step-by-step explanation:
First, find out how many messages are received a second. Do this by dividing messages by 60 seconds.
120/60 = 2 messages a second
now multiply 2 by 150
2*150 = 300messages in 150 seconds
your answer is (3) 300
120 / 18 = 20/3
x^3 / xy = x^2 / y
20x^2 / 3y
