Answer:

30 and 9

Step-by-step explanation:

x+y=39 , x-y=21

Solve for x:

x+y=39 , x-y=21

x= 30

Substitute x with 30:

(30)+y=39 , (30)-y=21

Solve for y:

y=9

Fernando purchased a new motorhome for $180,000, but the motorhome will depreciate
Dmitry_Shevchenko [17]

Your answer would be 122,400.

<em>To solve, follow these steps!! </em>First let's start with the price of the motorhome, 180,000. If it <em>depreciates, </em>that means it's going to lose value ever year.

It will depreciate 4% every year, so we need to find 4% of 180,000. You can just plug this into a calculator and get 7,200.

Next, it will depreciate for 8 years, so we multiply 7,200 x 8 and get 57,600. Lastly, we will subtract this from 180,000 and get 122,400.

Reptile [31]

Answer:

(2x + 1)(x - 3)

Step-by-step explanation:

y = 2 {x}^{2}  - 5x - 3

2 {x}^{2}  - 5x - 3 = 0

(2x + 1)(x - 3)  = 0

x =  -  \frac{1}{2}
