20 years will take for the group to have 290 member. In the year 2020 the group have 290 members, if the group was formed in the year 2000.
Step-by-step explanation:
The given is,
Points ( 2, 38 ) and ( 5, 80 )
Equation, [tex]y = 14x+10[/tex]...............................(1)
Where, x - number of years since the group was formed
y - number of members
Step:1
The given points are verifies the equation for the values relation between members and year of group,
If we apply x=2 years, the answer becomes members y=38. similarly for point (5, 80).
Step:2
For the first question,
Members, y = 290
From equation (1),
290 = 14 (x) + 10
290 - 10 = 14 (x)
280 = 14 (x)
x = [tex]\frac{280}{14}[/tex]
x = 20
No. of years, x = 20 years
Step:3
For second question,
From the step 1, 20 years will take for the group to have 290 members,
Group formed year = 2000
For 290 members = Group formed year + Years to have 290 members
= 2000+20
= 2020
For 290 members = 2020
Result:
20 years will take for the group to have 290 member. In the year 2020 the group have 290 members, if the group was formed in the year 2000.
Answer:
The answer is A. Membership grows by 14 each year.
