Use the linear equation “slope of a line” to find the slopes of the given points. m= y2-y1/x2-x1
4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5
n = 1/2
Answer:
The correct option is A.
Step-by-step explanation:
The general exponential growth model is defined as

Where, a is initial value, r is growth rate and x is time.
The initial population of town is 9800 and growth rate is 2%. The population growth model is defined as



Put x=7 to find the estimated population after 7 years.


Therefore the correct option is A.
Answer:
x = 48 ft
Step-by-step explanation:
Triangle DEF is similar to triangle XYZ
10 x 4 = 40 ft
so
12 x 4 = 48 ft
Answer
x = 48 ft
