The first step in determining the solution to the system of equations, y = -x2 - 4x - 3 and y = 2x + 5, algebraically is to set

sweet-ann [11.9K]

Answer:

Combine like terms onto one side of the equation

Step-by-step explanation:

You have

-x^2 -4x - 3 = 2x + 5

It seems that we should combine like terms to make this equations smaller.

-x^2 - 4x - 3 - 2x - 5 = 0

-x^2 -6x - 8 = 0

- (x + 2)(x + 4) = 0

x = -2 or x = -4

The length of a rectangle is 8 inches longer than half of its width.The area of the rectangle is 18 square inches.How many inche

SOVA2 [1]

Answer:

The correct answer is 2 inches.

Step-by-step explanation:

Let l inches and w inches be the length and width of a rectangle respectively.

According to the given problem, l - 8 = $\frac{w}{2}$ .

Area of the rectangle is given to be, according to the question, 18 square inches.

Thus l × w = 18

⇒ l × (2l - 16) = 18

⇒ 2 $l^{2}$ - 16l - 18 = 0

⇒ $l^{2}$ - 8l - 9 = 0

⇒ ( l - 9) ( l + 1) = 0

The possible values of l are 9 and -1. As the length cannot be equal to -1, thus the value of the length is 9 inches.

Width of the rectangle is 2 inches.

Which compound inequality is represented by the graph?

OLga [1]

<u>Answer-</u>

$\boxed{\boxed{x < -2\ or\ x \geq 4}}$

<u>Solution-</u>

As we know that, on the number line, if a number is on the right of another number, then the former number is greater than the later number.

As, the number on the right side are 4, 5, ...so on (4 is dotted so it is included)

So the inequality will be $x\geq 4$

As, the number on the left side are -3, -4, -5, ..... so on (-2 is not dotted so it is excluded)

So the inequality will be $x$

Then the compound inequality will be, $x < -2\ or\ x \geq 4$

Solve the given differential equation by using an appropriate substitution. the de is homogeneous. (y2 yx) dx − x2 dy = 0

Schach [20]

The solution for the given differential equation is lnlxl = $\frac{-x}{y} +C$

Given,

$(y^{2} +y^{x} )dx - x^{2} dy =0$

Here,

x = vy, dx = vdy + ydv

y = ux, dy = udx + xdu

Then,

$((ux)^{2} +(ux)x)dx-x^{2} (udx+xdu)=0\\=u^{2} x^{2} dx+ux^{2} dx-x^{2} udx-x^{3} du=0\\=u^{2} x^{2} dx=x^{3} du\\=\frac{x^{2} }{x^{3} } dx=\frac{1}{u^{2} } du$

Now,

$\int\limits^a_b {\frac{1}{x} } \, dx =\int\limits^a_b {u^{-2} } \, du$

l $n$ l $x$ l $=\frac{u^{-1} }{(-1)} +C$

l $n$ l $x$ l $=\frac{-1}{u} +C$

y = ux

u = $\frac{y}{x}$

That is l $n$ l $x$ l $=\frac{-x}{y} +C$
