Answer:
6 years
Step-by-step explanation:
Given
Required
When will it get to 4000
This question illustrates a geometric progression and will be solved using:
In this case;
So, we're to solve for n
Divide through by 150
Take Log of both sides
Apply law of logarithm
Take Log values
Make n - 1 the subject
Add 2 to both sides
(Approximated)
<em>Hence, it'll take 6 years</em>

➷ Pick any two sets of values
I will just select the first two:
(-2,-9) , (1,3)
First, you need to find the slope
slope = difference in y values / difference in x values
slope = (3-(-9)) / (1-(-2))
slope = 12 / 3
slope = 4
Substitute the slope into the general equation of a line form with one of the coordinates:
3 = 4(1) + c
3 = 4 + c
c = -1
The equation would be y = 4x - 1

Answer:
True, (-∞, ∞) 5 ≤ 11
Step-by-step explanation:
−11 ≤ −5 Add 16 to both sides
−11 + 16 ≤ −5 + 16
5 ≤ 11
The distributive property is being used because a is being distributed to b and c, which leaves you with ab + ac
