Is the equality sometimes always or never true? -2(2x+9)> -4x + 9
lys-0071 [83]
-2(2x+9)>-4x+9
1)We solve this inequation:
-2(2x+9)>-4x+9
-4x-18>-4x+9
-4x+4x-18>9
-18>9  This is not true, because -18<9; Therefore this inequation is never true.

Yuki888 [10]

Answer:

<em>Student 2 is incorrect because he didn't use the formula properly</em>

Step-by-step explanation:

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

C(t)=C_o\cdot(1-r)^t

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The initial value of the item is Co=$1000, the rate of decay is r=40%=0.4, and the time is t=3 years.

Substituting into the formula:

C(3)=\$1000\cdot(1-0.4)^3

C(3)=\$1000\cdot0.6^3

C(3)=$216

Student 2 is incorrect because he didn't use the formula properly
