i hope it will help you

Fractions are written as a ratio of two or more integers.

Given the expression

13/2x - 5/x

Find the LCM

From the given fraction, the LCM is 2x

= 13/2x - 5/x

= 13-2(5)/2x

= 13-10/2x

= 3/2x

Hence the difference in the fraction given in question is 3/2x

c) Equation of the circle

  [tex]\sqrt{(x+7)^2+(y-2)^2}=5[/tex]

Step-by-step explanation:

Given center of the circle C(-7,2) and containing the Point P(-3,5)

C P = r

C P  = [tex]\sqrt{(x_{2} -x_{1})^2+(y_{2} -y_{1} })^2 }[/tex]

C P  = [tex]\sqrt{(-3 -(-7))^2+(5 -2})^2 }[/tex]

C P = [tex]\sqrt{16+9} = 5[/tex]

The radius r = 5

The equation of the circle C(-7,2) and radius =5

[tex](x-h)^2+(y-k)^2 = (r)^2[/tex]

[tex](x-(-7))^2+(y-2)^2 = 25[/tex]

Answer: a

Step-by-step explanation:

The lineab bisects bi equally

Answer:

B, E and F.

Step-by-step explanation:

The transformation f(x) ------> f(x + a) moves f(x) a units to the left.

So when there is an increase in the number added to x in the parentheses the graph moves to the left.

So B is one because  of the (x  - 1)2 ---> (x + 1)2

The others are E and F.

The functions which has a graph in which the vertex and axis of symmetry are left of the vertex and axis of symmetry of the provided graph of f(x) are,

[tex]g(x) = -(x + 1)^2 - 2\\g(x) = -(x + 2)^2 + 2\\g(x) = 2(x + 1)^2 + 2[/tex]

Transformation of a function is shifting the function from its original place in the graph.

Types of transformation-

The function of the graph is,

[tex]f(x) = (x -1)^2 + 1[/tex]

The function to be left of the vertex of the above function, b units must be added in the parent function such that,

[tex]f(x+b)[/tex].

The option B, E and F looks like this function.

Thus, the functions which has a graph in which the vertex and axis of symmetry are left of the vertex and axis of symmetry of the provided graph of f(x) are,

[tex]g(x) = -(x + 1)^2 - 2\\g(x) = -(x + 2)^2 + 2\\g(x) = 2(x + 1)^2 + 2[/tex]

Answer:

The value of x is 6.

Step-by-step explanation:

You have to use Pythagorean Theorem, a² + b² = c². Make (4x+1)cm as the hypotenuse because any values substitute into x will give the highest length among these 3 expressions of length :

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

Let a = side = (x+1)cm,

Let b = side = 4x cm,

Let c = hypotenuse = (4x+1)cm,

[tex] {(x + 1)}^{2} + {(4x)}^{2} = {(4x + 1)}^{2} [/tex]

[tex] {x}^{2} + 2x + 1 + 16 {x}^{2} = 16 {x}^{2} + 8x + 1[/tex]

Then you have to simplify :

[tex]17 {x}^{2} + 2x + 1 = 16 {x}^{2} + 8x + 1[/tex]

[tex]17{x}^{2} + 2x + 1 - 16 {x}^{2} - 8x - 1 = 0[/tex]

[tex] {x}^{2} - 6x = 0[/tex]

Next you have to solve it :

[tex] {x}^{2} - 6x = 0[/tex]

[tex]x(x - 6) = 0[/tex]

[tex]x = 0 \: (rejected)[/tex]

[tex]x - 6 = 0[/tex]

[tex]x = 6cm[/tex]

The value of x in the right triangle is 6 cm.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

Right triangle:

The three sides are:

x + 1, 4x and 4x + 1

Applying the Pythagorean theorem.

(x + 1)² + (4x)² = (4x + 1)²

x² + 2x + 1 + 16x² = 16x² + 8x + 1

17x² + 2x + 1 = 16x² + 8x + 1

17x² - 16x² = 8x - 2x

x² = 6x

x gets canceled.

x = 6

Thus,

The value of x is 6.

Answer:

28.44$

Step-by-step explanation:

The original price of a shirt is A.

This shirt is on sale for 25% => the price of that shirt after being sale:

P1 = A - A x 25% = A - A x (25/100) = A - A x (1/4) = A x (3/4)

This shirt is discounted one more time for 25% => the price of that shirt after being discounted second time.

P2 = P1 - P1 x 25% = P1 - P1 x (25/100) = P1 - P1 x (1/4) = P1 x (3/4) = A x (3/4)^2

P2 is given to be equal to 16$, then there is an expression:

P2 = 16

or

A x (3/4)^2 = 16

=> A x (9/16) = 16

=> A = 16 x (16/9) = 28.44$

Answer:

5600 dollars

Step-by-step explanation:

The first thing we must do is calculate the area of the rectangle since the value is given per unit area.

They give it per square centimeter, therefore we must pass the measurements from meters to centimeters, knowing that 1 meter is 100 centimeters:

4m * 100cm / 1m = 400cm

5m * 100cm / 1m = 500cm

Now the area would be:

A = 400 * 500 = 20000

20000 cm ^ 2 would be the area of the rectangular wall, we calculate the value like this:

20000 * 0.28 = 5600

In other words, it has a value of 5600 dollars.

Answer:

Step-by-step explanation:

Given M is directly proportional to r³ then the equation relating them is

M = kr³ ← k is the constant of proportion

To find k use the condition r = 4 when M = 160, thus

160 = k × 4³ = 64k ( divide both sides by 64 )

2.5 = k

M = 2.5r³ ← equation of proportion

(a)

when r = 2, then

M = 2.5 × 2³ = 2.5 × 8 = 20

(b)

when M = 540 , then

540 = 2.5r³ ( divide both sides by 2.5 )

216 = r³ ( take the cube root of both sides )

[tex]\sqrt[3]{216}[/tex] = r , thus

r = 6

Answer:

A) 26°

Step-by-step explanation:

In quad ABCD

C = 90°

B = 2y

A = 180 - 68

D= 180 - (y+48)

In a quad sum of all angles = 360°

therefore,

A + B + C + D = 360°

90 + 2y + 360 - 68 - y - 48 = 360

90-116+y = 0

y = 26°

Answer:

Step-by-step explanation:

The equation is 0 + 59 = 17 which can help Aly calculate the number of more toy cars than trucks. which is the correct answer would be an option (C).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have been given that Aly has 59 toy cars and 17 toy trucks.

To determine the equation can help Aly calculate number of more toy cars than trucks she has

We have to subtract 17 from both sides and add 0

0 + 59 = 17

0 + 59 - 17 = 42

Therefore, the equation is 0 + 59 = 17 which can help Aly calculate the number of more toy cars than trucks.

Hence, the correct answer would be option (C).
