find the difference between two points
Answer:
no solution
Step-by-step explanation:
Given
(21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )
21 - 3a = 18 - 3a ( subtract 21 from both sides )
- 3a = - 3 - 3a ( add 3a to both sides )
0 = - 3 ← not possible
This indicates the equation has no solution
We can use the equation [ f(x) = 16*4^(x-1) ] where x equals the year of study.
f(7) = 16*4(7-1)
f(7) = 16*4^6
f(7) = 16*4096
f(7) = 65,536
There is no option that resembles the correct answer.
Best of Luck!
