The answer is 25, it moves 8 points x and 17 points y.
Answer:
dA/dt = k1(M-A) - k2(A)
Step-by-step explanation:
If M denote the total amount of the subject and A is the amount memorized, the amount that is left to be memorized is (M-A)
Then, we can write the sentence "the rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized" as:
Rate Memorized = k1(M-A)
Where k1 is the constant of proportionality for the rate at which material is memorized.
At the same way, we can write the sentence: "the rate at which material is forgotten is proportional to the amount memorized" as:
Rate forgotten = k2(A)
Where k2 is the constant of proportionality for the rate at which material is forgotten.
Finally, the differential equation for the amount A(t) is equal to:
dA/dt = Rate Memorized - Rate Forgotten
dA/dt = k1(M-A) - k2(A)
This equation is not liner because the equation is not a straight line. At the point (0, 23) the equation bends.
x 26
----- = -----
48 100
cross-multiply...
100x = 48*26
then solve for x
Hope this helps!
Square root of 5x+1=6
square root each side
5x+1=6 squared
5x+1=36
subtract 1 on both sides
5x=35
divide both sides by 5
x=7
