f(x) = 9x - 4.5
Substitute 2 for x
f(2) = 9(2) - 4.5
Multiply 9 by 2
f(2) = 18 - 4.5
Subtract
Final Answer: f(2) = 13.5

konstantin123 [22]

Answer:

x=11.

Step-by-step explanation:

Start by writing out the equation:

2x-5y=17

Then replace y with 1:

2x-5(1)=17

Multiply -5 by 1.

2x-5=17

+5 +5

Then add 5 to both sides.

2x=22

Divide 22 by 2:

x=11

the function Q(t)= Q(base o) e^(-kt) maybe be used to model radioactive decay. Q represents the quantity remaining after t years

Tanzania [10]

Half-Life = ln (.5) / k
Half-Life = .693147 / .00011
Half-Life = 6,301 years

For a radioactive substance to decay to 25%, it has to go through 2 halflives.

2 * 6,301 = 12,602 years
approximately 12,600 years
