Answer:
14

Step-by-step explanation:
you first have to move 4x to the right side and then add 20 yo the left side to get what i got
Answer:
1, 4 and 5
Step-by-step explanation:
Remmeber you can do anything to an equaiton as long as you do it to btoh sides
5-6(a+2)=7+a
distribute
5-6a-12=7+a
add like terms
-6a-7=7+a
add 6a both sides
-7=7+7a
minus 7 both sides
-14=7a
divide by 7
-2=a
a=-2
Im not sure about equation 1 because theres a 3 after the y and i dont know if that was an error but if it was and its actually meant to read : y=2x+1 then equation 1 &2 are both linear functions.
Answer:
n=6.77 months (exactly)
n=7 months (nearest integer, less accurate)
Step-by-step explanation:
A) The initial number of bees in a colony is 1500. Each month the number of bees decreases by 12% which means each month we must factor by (1-0.12)=0.88
So the number of bees as a function of n months is
1500*0.88*0.88...0.88 (n times)

The initial number of flowering plants is 800 and there are 25 fewer of them each month. It can be written as

B) After 6 months (n=6) there will be

And there will be
flowering plants
C) We want to know the value of n that make B = P:

Rearranging

This equation cannot be solved by exact procedures, we must approach the answer or use any numerical method to solve for n
The best value to solve the equation is n = 6.77 months in which case

And
flowering plants
If we wanted to use only integers for n, then we should use the nearest integer to our previous value, that is, n=7. In this case,

flowering plants
