Y=7x-19

-2x+3(7x-19)=-19
-2x+21x-57=-19
19x-57=-19
19x=38
x=2

-7(2) + y = -19
-14 + y = -19
y=-5

1. (a) Solve the differential equation (x + 1)Dy/dx= xy, = given that y = 2 when x = 0. (b) Find the area between the two curves
erastova [34]

(a) The differential equation is separable, so we separate the variables and integrate:

(x+1)\dfrac{dy}{dx} = xy \implies \dfrac{dy}y = \dfrac x{x+1} \, dx = \left(1-\dfrac1{x+1}\right) \, dx

\displaystyle \frac{dy}y = \int \left(1-\frac1{x+1}\right) \, dx

\ln|y| = x - \ln|x+1| + C

When x = 0, we have y = 2, so we solve for the constant C :

\ln|2| = 0 - \ln|0 + 1| + C \implies C = \ln(2)

Then the particular solution to the DE is

\ln|y| = x - \ln|x+1| + \ln(2)

We can go on to solve explicitly for y in terms of x :

e^{\ln|y|} = e^{x - \ln|x+1| + \ln(2)} \implies \boxed{y = \dfrac{2e^x}{x+1}}

(b) The curves y = x² and y = 2x - x² intersect for

x^2 = 2x - x^2 \implies 2x^2 - 2x = 2x (x - 1) = 0 \implies x = 0 \text{ or } x = 1

and the bounded region is the set

\left\{(x,y) ~:~ 0 \le x \le 1 \text{ and } x^2 \le y \le 2x - x^2\right\}

The area of this region is

\displaystyle \int_0^1 ((2x-x^2)-x^2) \, dx = 2 \int_0^1 (x-x^2) \, dx = 2 \left(\frac{x^2}2 - \frac{x^3}3\right)\bigg|_0^1 = 2\left(\frac12 - \frac13\right) = \boxed{\frac13}

Find the AGI and taxable income:
Juli2301 [7.4K]
This "question" isn't even a question. If the question is asking to calculate AGI and taxable income I can definitely help. This is what I do for a living! I am assuming this is 3 questions.   
1. Find the AGI and taxable income: Gross Income $30,856 Adjustments $750 1 Exemption $8200 Deduction $2,300 
 AGI: $31,200 and $20,601 $30106 --- ANSWER: 30,106 (30,856-750)
 Taxable Income: $19,606 $29,586 and $18,505 $28,863 and $17,636 1 points--- ANSWER 19,606 
 2. QUESTION 5 Find the AGI and taxable income. Gross Income $67,890
Adjustments $0 3 Exemptions $24,600 Deduction $1469 
 AGI: $69,440 and $45,300 $68,990 and $42,831 $67,890 --- ANSWER:
67,890
 Taxable Income: $41,821 $65,551 and $44,821 1 points --- ANSWER: 41,821 (67,890-24,600-1,469) 
 3. QUESTION 6 Find the AGI and taxable income. Gross income $19,723 Adjustments $255 1 Exemption $8200 Deduction $1430 $19,4
 AGI: 19,468 (19,723-255)
 Taxable Income: 9,838 (19,468-8,200-1,430) 
 Goodluck! If you need anything else feel free to reach out to me directly. Not sure if you can I'm fairly new to this.
