Look at this:
2x+$2,000=$28,000
2x=$28,000-$2,000
2x=$26,000
x=26,000 divided by 2
x=$13,000
Answer:
A the graph represents a linear function because
Step-by-step explanation:
Answer: 41.5 min
Step-by-step explanation:
This problem can be solved with the Radioactive Half Life Formula:
(1)
Where:
is the final amount of the radioactive element
is the initial amount of the radioactive element
is the time elapsed
is the half life of the radioactive element
So, we need to substitute the given values and find from (1):
(2)
(3)
(4)
Applying natural logarithm in both sides:
(5)
(6)
Clearing :
This is the time elapsed
Answer:
A) T = -1.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10t+4−2t=2−2(t+4)
10t+4+−2t=2+(−2)(t)+(−2)(4)(Distribute)
10t+4+−2t=2+−2t+−8
(10t+−2t)+(4)=(−2t)+(2+−8)(Combine Like Terms)
8t+4=−2t+−6
8t+4=−2t−6
Step 2: Add 2t to both sides.
8t+4+2t=−2t−6+2t
10t+4=−6
Step 3: Subtract 4 from both sides.
10t+4−4=−6−4
10t=−10
Step 4: Divide both sides by 10.
Hope this helps!

Hello.
In order to solve this equation, we need to isolate the variable (in this case, the variable is x)
The first step is to use the Distributive Property and distribute 3:
Now, add 3 to both sides:
Now, subtract 2x from both sides:
Therefore, the answer is
I hope it helps.
Have a nice day.
