Answer:
b. because m = -5
Step-by-step explanation:
y = -5x +9
m (gradient) is the coefficient before the 'x' term
Answer and Step-by-step explanation: The graph is shown in the attachment.
a. ΔR on [1,2] is mathematically expressed as:
ΔR = R(2) - R(1)
which means difference of population of rabbits after 2 months and after 1 month.


R(2) = 


![\Delta R = 100[\frac{4}{5} - \frac{2}{5} ]](https://tex.z-dn.net/?f=%5CDelta%20R%20%3D%20100%5B%5Cfrac%7B4%7D%7B5%7D%20-%20%5Cfrac%7B2%7D%7B5%7D%20%5D)
40
Difference of rabbits between first and second months is 40.
b. R(0) = 100(
)
R(0) = 0
Initially, there no rabbits in the population.
c. R(10) = 
R(10) = 400
In 10 months, there will be 400 rabbits.
d. R(t) = 500



t = 12.5
In 12 and half months, population of rabbits will be 500.
-10 -10y = 10
+10 +10
-10y = 20
20/-10 = -2
Y = -2
Answer:
Step-by-step explanation:
3+√5 is a root.
so 3-√5 is also a root
or (x-(3-√5)) is also a factor of f(x)
Three possible points are:
(-3, 0)
(0, 2)
(3, 4)
To find any points, simply select any value for x. Input that value, then find the corresponding y-value.
For example, if x = 0, then:
-3y = -2(0) - 6
-3y = -6
y = 2
