Answer:
-6
Step-by-step explanation:
firstly arrange whole equation,
-2x+7=19
Now, Transpose 7 to RHS (right hand side)
-2x=19-7
-2x=12
Further, seperate coefficient -2 from x
and transpose it to RHS and divide them
x=12/-2
Hence, x= -6
Answer:
4/7 = 40/70
3/10 = 21/70
Step-by-step explanation:
Each week, there are 24+12x more new instances recorded than there was the previous week which is increasing exponentially.
There were 24 cases of flu reported in a city's hospital on January 4.
In the next 5 weeks, the number of new cases reported each week had grown exponentially.
Let "A" represent the number of flu cases at time "t." Any population "A" grows exponentially over time at a rate of "t." The beginning population directly affects the rate of population change.
dA/dt = k( T - 24 )
T- 24 = c ×
[Differentiate with 't']
T = 24 + c ×
After 1 week T = 36 and t = 1
36 - 24 = c × 1
c = 12
T = 24 + 12x.
Therefore, 24 + 12x new instances have been reported each week, increasing exponentially.
