Answer:
1.) y = 1/2x -1.8 slope is 1/2 and y intercept is - 1.8
Step-by-step explanation:
1.) 5x - 10y = 18
<u> +10y +10y</u>
5x = 10y +18
<u>- 18 -18</u>
<u>5x - 10y</u> = <u>18</u>
<u> 10 10</u>
= 1/2x -1.8
Answer:
In 1981 was the building worth double it’s value.
Step-by-step explanation:
Given : A townhouse in San Francisco was purchased for $80,000 in 1975. The appreciation of the building is modeled by the equation :
, where t represents time in years.
To find : In what year was the building worth double it’s value in 1975?
Solution :
The amount is $80,000.
The building worth double it’s value in 1975.
i.e. amount became A=2(80000).
Substitute in the model,



Taking log both side,



i.e. Approx in 6 years.
So, 1975+6=1981
Therefore, in 1981 was the building worth double it’s value.
