⇒The answer is  (x-5)(3x+2)

Answer:

12 ft, 13 ft , 17 ft

Step-by-step explanation:

let x be the length of the second side , then

one side is x + 1

third side is x + 5

the perimeter P is the sum of the 3 sides, then

P = x + x + 1 + x + 5 ← collect like terms

P = 3x + 6

given P = 42 , then equating gives

3x + 6 = 42 ( subtract 6 from both sides )

3x = 36 ( divide both sides by 3 )

x = 12

x + 1 = 12 + 1 = 13

x + 5 = 12 + 5 = 17

the 3 sides are 12 ft, 13 ft , 17 ft

The sign of coordinate of x of a point after the reflection along the y-axis will be interchanged thus the coordinate of K'(2,5).

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

The given point K(-2,-5)

If we reflect a point(x,y) along the y-axis then the coordinate after reflection converts as K'(-x,y)

The reflection of K(-2,-5) along the y-axis will be  K'(2,5).

Hence "The sign of coordinate of x of a point after the reflection along the y-axis will be interchanged thus the coordinate of K'(2,5)".

The required expression is 3h(150) + h(270) which is the correct answer would be an option (D).

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Since each house will have 3 smaller bedrooms that required 150 square feet of carpet

⇒ 3 × 150

Each house will have 1 larger bedroom that requires 270 square feet of carpet.

⇒ 270

So, (3 × 150 + 270) × h

⇒ 3h(150) + h(270)

Thus, The required expression is 3h(150) + h(270).

The ellipse given by x^2+xy+2y^2=7. The y-coordinate(s) of all points are -11.3, 11.2, -5.665, 5.585 where the ellipse has a vertical tangent line.

Differentiation is the process of determining a function's derivative. Differentiating algebraic functions, trigonometric functions, and exponential functions are the three fundamental derivatives.

Given,

Ellipse given,

x²+ xy + y ² = 7

Differentiating:

dy/dx

x²+ xy + y² = 7

d/dx(x² + xy + y²) = d/dx(7)

2x + 1y + x dy/dx + 2y dy/dx = 0

dy/dx = 2x + y/ x + 2y

dy/dx = 0

2x + y = 0

x + 2y = 0

Now, we have 2 equations,

x² + xy + y² = 0

y = -2x

Solving equations by substitution method,

x² + x(-2x) + (-2x)² = 7

x² - 2x² + 4x² = 7

3x² = 7

x = ±√21/3

Using y = -2x

Points are:

( -2√21/3 , √21/3) and (2√21/3 , -√21/3)

±√21/3 = ±1.528

x² + xy + y² = 7 [-11.3, 11.2, -5.665, 5.585]}

The solution to the equation given as 2x + 4y = 6x − y has the ordered pair of (3, 4)

From the question, we have the following equation that can be used in our computation:

2x+4y=6x−y

Solving further, we need to collect the like terms

So, the equation becomes

2x - 6x = -4y - y

Next, we evaluate the like terms in the above equation

So, we have the following representation

-4x = -3y

Divide both sides by -3

The equation becomes

x = 3/4y

At this point, we assume any value for y and then solve for x

Assume that the value of y is 4

So, we have the following representation

x = 3/4 * 4

Evaluate the products

x = 3

So, we have

x = 3 and y = 4

Express as ordered pairs

(x, y) = (3, 4)

Hence, the ordered pair of the solution is (3, 4)

Answer:

Multiply and divide by √2 . You'll get √22

Step-by-step explanation:

The equation of the line perpendicular to the given line is, y = 3x + 1.

What is slope of the line?

The change in y coordinate relative to the change in x coordinate is referred to as a line's slope in mathematics. The symbols Δy and Δx stand for the net change in the y-coordinate and the net change in the x-coordinate, respectively. where "m" denotes a line's gradient. tanθ then represents the slope of a line.

Consider, the given equation of line

[tex]y = -\frac{1}{3}x+4[/tex]

We have to find the equation of line passes through the point (-2, -5) and perpendicular to the given line.

Here, the point is (-2, 5).

First to find the slope of the line.

Since, the slope of the line, perpendicular to the given line is negative reciprocal of the slope of given line.

Here, the slope of given line is, -1/3.

So, the slope of perpendicular line is [tex]-(\frac{1}{(-\frac{1}{3}) }) = 3[/tex]

Therefore, the slope of the line is 3.

Now to find the equation of the line.

Consider, the point - slope form of the line

[tex]y-y_1=m(x-x_1)[/tex]

Plug [tex](x_1, y_1) = (-2, -5) , m = 3[/tex]

⇒

[tex]y-(-5)=3(x-(-2))\\y+5=3(x+2)\\y+5=3x+6\\y=3x+6-5\\y=3x+1[/tex]

Hence, the equation of line in slope - intercept form, is y = 3x + 1.

What are coordinates?

A pair of numbers that use the separations between the two reference axes to define the location of a point on a coordinate plane. usually represented by the x- and y-values, respectively, (x, y).

The position of a point or a shape in a given space is determined by coordinates, which are numbers (a map or a graph ).

The points are in the form of ( x, y) , where y= g(x)

Plot these points on the graph and join the points through a line.

Refer to the attachment for the graph.

The slope is constant.
