4b + 22 = 5 (b + 4) - 1 (remove the parantheses)
4b + 22 = 5b + 20 - 1 (calculate)
4b + 22 = 5b + 19 (move the terms)
4b - 5b = 19 - 22 (collect like terms and calculate)
-b = -3 (change the signs)
<em>b = 3</em>

if you want a fraction then 4/1 which is the same thing as saying 4
Answer:
10 growth per 1000.
Step-by-step explanation:
Given,
Rate of birth = 30 births per 1000
Rate of death = 20 deaths per 1000
As the growth in population is the difference in the number of the child take birth and the person die.
As we are calculating the rate of birth and rate of growth in per thousands of members, so the growth rate will be also in per thousands.
As we can see on every one thousand people,
total birth = 30
total death = 20
so, total growth = total birth - total growth
= 30 - 20
= 10
As at every 1000 persons, there are 10 persons survive, so the rate of growth will be 10 growth per 1000.
Answer:
see below
Step-by-step explanation:
Well there are two main reasons
1. exponential functions don't have a negative value, i mean
2. well exponential functions are like a curve, the firsts values are very close to each other, but then they start jumping like mad (translate it to your own words), for example in
the first positive values are
1,2,9 but then 16,25,36,49
