Answer: 6 = - 2.
Step by step explanation:
Subtract 4b from 7b.
3b + 3 = 3 - 3 (b+4)
Simplify 3 - 3 (b+4).
3b + 3 = - 3b - 9
Move all terms containing b to the left side of the equation.
6b + 3 = - 9.
Move all terms not containing b to the right of the equation.
6b = - 12
Divide each term by 6 and simplify.
And, voila! You have your answer, 6 = - 2.

false
Step-by-step explanation:
what exactly is the equation? If it's true or false it's false.
Answer:
The linear function that discribes the size of the population in function of the t in years is p = 700t - 1,397,300
Step-by-step explanation:
A linear function is defined by a line, so in order to determine the linear function we can use the two points that were given to us to create a line equation and use that as our linear function. The points given to us were (2009; 9000) and (2014; 12500), in this case the year is our value of "x" and the size of the population is our value of "y". The first step is to find the slope of the line which is given by:
m = (y2 - y1)/(x2 - x1)
m = (12500 -9000)/(2014 - 2009) = 3500/5 = 700
Then we can use the slope and the first point to build the equation:
p - 9000 = 700*(t - 2009)
p = 700t - 1406300 + 9000
p = 700t - 1397300
