If the coefficient is positive, then just multiply or divide by the same coefficient.
2X less than or equal to 8
divide by 2 throughout to get X is less than or equal to 4

If the coefficient is negative, then multiply or divide by the negative sign and the same number throughout
-2X is less than or equal to 8
divide by -2 throughout to get
 X is GREATER THAN OR EQUAL to 8.
Remember the sign changes when you divide or multiply by negative.

Josephine purchased a used vehicle that depreciates under a straight-line
lys-0071 [83]

Answer:

D. $4000

Step-by-step explanation:

Initial value of the car is given $5000

Salvage value given $500

Useful life of car given is 5 years

Formula

Depreciation for n years is given as:

d_{n}= \textrm{Salvage value}\times \textrm{Number of years used}

d_{n}=\textrm{Salvage Value}\times n

Plug in 2 for n. This gives,

d_{2}=500\times 2=1000

∴ Depreciation after 2 years =$ 1000

Value of car after 2 years = Initial value - Depreciation after 2 years

Value of car after 2 years = 5000- 1000=4000

Therefore, value of car after 2 years = $ 4000
