Four items are on sale at a local store. A shirt was originally $9.50 and now is $7.60. A pair of jeans were $25.00, and now the

y are priced $20.00. A pair of boots were $55.00, and they are on sale for $44.00. Do these regular and sale prices represent a proportional relationship

Answer : Yes, regular and sale prices represent a proportional relationship.

Step-by-step explanation :

We have to determine the ratio of regular and sale prices of shirt, jeans and boots .

A shirt was originally $9.50 and now is $7.60.

$\frac{\text{Regular price}}{\text{Sale price}}=\frac{\$ 9.50}{\$ 7.60}$

$\frac{\text{Regular price}}{\text{Sale price}}=\frac{5}{4}$

A pair of jeans were $25.00, and now they are priced $20.00.

$\frac{\text{Regular price}}{\text{Sale price}}=\frac{\$ 25.00}{\$ 20.00}$

$\frac{\text{Regular price}}{\text{Sale price}}=\frac{5}{4}$

A pair of boots were $55.00, and they are on sale for $44.00.

$\frac{\text{Regular price}}{\text{Sale price}}=\frac{\$ 55.00}{\$ 44.00}$

$\frac{\text{Regular price}}{\text{Sale price}}=\frac{5}{4}$

From this we conclude that, all the items are in same ratio that means the regular and sale prices represent a proportional relationship.

Hence, yes, regular and sale prices represent a proportional relationship.

2(x+5)-3=-(2x+1)+1<br> What is the solution for x???

netineya [11]

Hi there,

2 (x +5) - 3 = -(2x + 1) + 1
2x + 10 - 3 = -2x - 1 + 1
2x + 10 - 3 = -2 - 1 + 1
2x + 7 = -2x
2x + 2x = -7
4x = -7

Hence, X= -7/4

Hope this helps :)

Solve the initial value problems.

Both equations are linear, so I'll use the integrating factor method.

The first ODE

$xy' + (x+1)y = 0 \implies y' + \dfrac{x+1}x y = 0$

has integrating factor

$\exp\left(\displaystyle \int\frac{x+1}x \, dx\right) =\exp\left(x+\ln(x)\right) = xe^x$

In the original equation, multiply both sides by eˣ :

$xe^x y' + (x+1) e^x y = 0$

Observe that

d/dx [xeˣ] = eˣ + xeˣ = (x + 1) eˣ

so that the left side is the derivative of a product, namely

$\left(xe^xy\right)' = 0$

Integrate both sides with respect to x :

$\displaystyle \int \left(xe^xy\right)' \, dx = \int 0 \, dx$

$xe^xy = C$

Solve for y :

$y = \dfrac{C}{xe^x}$

Use the given initial condition to solve for C. When x = 1, y = 2, so

$2 = \dfrac{C}{1\cdot e^1} \implies C = 2e$

Then the particular solution is

$\boxed{y = \dfrac{2e}{xe^x} = \dfrac{2e^{1-x}}x}$

The second ODE

$(1+x^2)y' - 2xy = 0 \implies y' - \dfrac{2x}{1+x^2} y = 0$

has integrating factor

$\exp\left(\displaystyle \int -\frac{2x}{1+x^2} \, dx\right) = \exp\left(-\ln(1+x^2)\right) = \dfrac1{1+x^2}$

Multiply both sides of the equation by 1/(1 + x²) :

$\dfrac1{1+x^2} y' - \dfrac{2x}{(1+x^2)^2} y = 0$

and observe that

d/dx[1/(1 + x²)] = -2x/(1 + x²)²

Then

$\left(\dfrac1{1+x^2}y\right)' = 0$

$\dfrac1{1+x^2}y = C$

$y = C(1 + x^2)$

When x = 0, y = 3, so

$3 = C(1+0^2) \implies C=3$

$\implies \boxed{y = 3(1 + x^2) = 3 + 3x^2}$
