Answer: 9x-3
Step-by-step explanation:
Answer:
x = 3 x = 7 Okay well I got C. f(x) = x2 - 10x + 21 I got it because u subtract and add at the last part.
Step-by-step explanation:
Answer:
The general solution of the equation is y = 
+ 5
Step-by-step explanation:
Since the differential equation is given as y'(t) = 3y -5
The differential equation is re-written as
dy/dt = 3y - 5
separating the variables, we have
dy/(3y - 5) = dt
dy/(3y - 5) = dt
integrating both sides, we have
∫dy/(3y - 5) = ∫dt
∫3dy/[3(3y - 5)] = ∫dt
(1/3)∫3dy/(3y - 5) = ∫dt
(1/3)㏑(3y - 5) = t + C
㏑(3y - 5) = 3t + 3C
taking exponents of both sides, we have
exp[㏑(3y - 5)] = exp(3t + 3C)
3y - 5 = 
3y - 5 = 
3y = + 5
dividing through by 3, we have
y = + 5
So, the general solution of the equation is y = + 5
The equation is in standard form. Standard form is in this formula:
Ax + By = C
To convert a standard form to slope intercept form you first move Ax to the other side of the equation by inverse operations.
2x + 1.50y = 15
-2x -2x
1.50y = -2x + 15
You then divide B (From By) across the whole equation. (If you can't evenly divide make it a fraction)
1.50y = -2x + 15
1.50 1.50
y = -2/1.50x + 10
Dividing 3.6 by 0.25 follows the following generic approach : You have
to firstly need to multiply both divisor and dividend by that number
such that the divisor becomes a whole number first .
So we multiply both dividend and divisor by 100 such that the problem converts to 3.6*100/0.25*100 = 360 being divided by 25 .
So the approach to divide a number froma decimal number is to first
convert problem into dividing the number from a whole number , by
multiplying both the number and divisor from the approriate number .
Which was in above problem comes out to be 100 .
