Step-by-step explanation:
you work with it like with regular equations :
-9 <= 5 + 2x <= -5
-14 <= 2x <= -10
-7 <= x <= -5

4. the initial population
Answer:
slope = 2
Step-by-step explanation:
Pick two points to find the slope. (1, 2) and (3, 3)
From the left (1, 2) to (3, 3), it goes up 2 units and to the right 1 unit.
We can plug this into the slope equation which is rise/run
2/1 = 2 = slope
Answer:
Number of year = 11.725 year (Approx.)
Step-by-step explanation:
Given:
Amount invested = $200
Interest rate = 6% (compounded semi annually)
Future value = 2 x Amount invested
Find:
Number of year
Commutation:
Future value = 2 x Amount invested
Future value = 2 x 200
Future value = $400
Number of year (Semi-annual) = 2n
Interest rate (Semi-annual) = 6% / 2 = 3%
So.
A = P[1+r]ⁿ
400 = 200[1+3%]²ⁿ
2 = [1.03]²ⁿ
n = 11.725 year
Number of year = 11.725 year (Approx.)
So slope is rise/run so 5/1 would be your slope. Hope this helped.
