Answer:

x = - [tex]\frac{3}{2}[/tex], x = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Given

2(6x² + 5x) = 12 ( divide both sides by 2 )

6x² + 5x = 6 ( subtract 6 from both sides )

6x² + 5x - 6 = 0 ← in standard form

(2x + 3)(3x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex]

3x - 2 = 0 ⇒ 3x = 2 ⇒ x = [tex]\frac{2}{3}[/tex]

Answer:

k = 77

Step-by-step explanation:

k ÷ 11 = 7

We can reverse the equation to 7 x 11 =k

Using the multiplication tables, we know that 7 x 11 is 77

Therefore:

k = 77

Plug it in:

77 ÷ 11 = 7

Answer:

77

Step-by-step explanation:

K ÷ 11 = 7

K = 7 × 11

K = 77

K is 77

Answer:

[tex]\$\,450+0.05\cdot V \geq \$\,600[/tex]

Step-by-step explanation:

El salario semanal es la suma de un coste fijo y un coste variable en función de las ventas logradas. El enunciado puede traducirse en la siguiente desigualdad:

[tex]\$\,450+0.05\cdot V \geq \$\,600[/tex]

Donde [tex]V[/tex] es el monto semanal de ventas, medido en pesos.

T is the midpoint of the line, meaning that in line SU, line ST and line TU are of equal length, since T is at the middle of the line.

[tex]9x=4x+25[/tex]

[tex]5x=25[/tex]

[tex]x=5[/tex]

[tex]ST=9x[/tex]

[tex]ST=9*5[/tex]

[tex]ST=45[/tex]

Hope this helps. 頑張って!

Answer:

Box 1

Step-by-step explanation:

If you look carefully, you will notice that Boxes 2, 3, and 4 are all equations. We know this because they all have the "=" sign. On the other hand, Box 1 is an expression. We know this because it doesn't have an "=" sign. Therefore, Box 1 is the odd one out.

Answer:

[tex] \boxed{ \bold{ \sf{Price \: of \: the \: article = \: Rs \: 6678.3}}}[/tex]

[tex] \boxed{ \bold{ \sf{Vat \: amount = \: \: Rs \: 768.3}}}[/tex]

Step-by-step explanation:

Given,

Marked Price ( MP ) = Rs 6000

Vat percent = 13 %

Discount percent = 15%

▪️Finding the discount amount

Discount amount = Discount % of MP

= 15 % of 6000

= Rs 900

▪️Finding the selling price

Selling price ( SP )= Marked price - Discount amount

= Rs 6000 - Rs 900

= Rs 5910

▪️Finding the vat amount

Vat amount = Vat % of SP

= 13 % of 5910

= Rs 768.3

▪️Finding SP with VAT

SP with vat = SP + vat amount

= Rs 5910 + Rs 768.3

= Rs 6678.3

Hope I helped!

Answer: -2, 0, and 2.

Step-by-step explanation: You are given the relation R = {(-3, -2), (-3, 0), (-1, 2), (1, 2)} The domain of the relation are all possible inputs and the range of the relation are all possible outputs. So, the inputs are : -3,-1,1; and the outputs are : -2,0,2. As a result, the domain is : -3,-1,1; and the range is : -2,0,2.

the numbers that are in the range of the relation R are -2, 0, and 2.

To determine the numbers that are in the range of the given relation R, we need to identify the second components (y-values) of each ordered pair in the relation.

The range of a relation consists of all the unique y-values that are paired with x-values in the relation.

For the given relation R = {(-3, -2), (-3, 0), (-1, 2), (1, 2)}, the second components (y-values) are:

-2, 0, 2, 2.

To find the numbers that are in the range, we look for the unique values among these y-values:

-2, 0, 2.

Therefore, the numbers that are in the range of the relation R are -2, 0, and 2.

Complete question :

The number of birds (b) in a park increases when the number of dogs in the park (d) decreases. Write the correct equation for this scenario, and solve for the number of birds when there are 10 dogs.

Dogs(d) - - birds(b)

40 - - - - - - 10

50 - - - - - - 8

Answer:

b = k/d ; 40

Step-by-step explanation:

From the table:

Dogs(d) - - birds(b)

40 - - - - - - 10

50 - - - - - - 8

The number of birds(b) in a park increases when the number of dogs (d) decreases.

Hence we can infer that an inverse relationship exists between them.

Number of birds(b) ∝ 1 / number of birds

b ∝ 1 / d

b = k/d

k = (b × d)

Where k is the proportionality constant

When d = 40, b = 10

Solve for k

k = (40 * 10)

k = 400

Therefore, number of birds(b), when there are 10 dogs;

b = k/d

k = 400, d = 10

b = 400 / 10

b = 40

40 birds when dogs = 10

Answer:

{x | -1 < x ≤ 2}

Step-by-step explanation:

Interval given in the notation of (a, b) denotes,

Upper limit at 'b' and lower limit at 'a'

Sign () denotes the interval between a and b exclusive of the numbers a and b.

Interval given as [a, b] represents,

a = lower limit

b = higher limit

Notation of [] show the interval inclusive of these numbers.

Given set in the question is (-1, 2]

Here (-1) is the lower limit and 2 is the upper limit.

(] notation shows exclusive of (-1) and inclusive of 2.

Therefore, solution set in set-builder notation will be {x | -1 < x ≤ 2}

Answer:

5

Step-by-step explanation:

Because 3 x -2 -6 and -6+6=0 so -2+7 has to be 5

The required value of X + 7 is equal to 5.

An expression is given in the question ; i.e., 3x + 6 = 0

We have to find out the value of the 'X + 7'.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , division , etc.

As per the question ;

The given expression is 3x + 6 = 0

Let's solve it to get the value of x.

i.e.,

3x + 6 = 0

3x = - 6

x = - 2

So ,

The value of X + 7 will be ;

= -2 + 7

= 7 - 2

= 5

Thus , the required value of X + 7 is equal to 5.

Answer:

13

Step-by-step explanation:

Hello, we can write a two digit number 'ab' as 10 * a + b, where a and ba are two integer between 0 and 9.

For instance, 54= 50 + 4 = 5 *10 + 4, a = 5 b = 4, right?

The sum of a two digit number is 4.

a + b = 4

If the order of the digits are reversed, the result is a number that exceeds the original number by 18.

10b + a = 10a + b + 18

9b = 9a + 18

b = a + 2

We can replace in the first equation,

a + a + 2 = 4

2a = 2

a = 1

and then, b = 3

So the number is 13.

thank you

Answer:

The two consecutive even integers = (4, 6)

Step-by-step explanation:

We are asked in the question to find two consecutive even integers such that 5 times their sum is 26 more than their product.

Two consecutive even integers is represented as: x, x + 2

Five times their sum is 26 more than their products

5( x + x + 2) = [x × (x + 2)] + 26

5( 2x + 2) = (x² + 2x) + 26

10x + 10 = (x² + 2x ) + 26

x² + 2x + 26 - 10x - 10 = 0

x² - 8x + 16 = 0

We factorise

x² - 4x - 4x + 16 = 0

(x² - 4x) -(4x + 16) = 0

x(x - 4) -4(x - 4) = 0

(x - 4)(x - 4) = 0

(x - 4)²

Hence

x - 4 = 0

x = 4

Since, we know that two consecutive even integers = (x , x + 2)

First even integer = x = 4

Second even integer = x + 2 = 4 + 2

= 6

Therefore, the two consecutive even integers = (4, 6)

Explanation:

The coefficient is the number just to the left of the variable. So that's why -8 is the coefficient for -8x. This is the variable term while 15 is the constant (it has no variable multiplied with it). The two terms are 15 and -8x since we can write 15-8x as 15+(-8x). Terms are separated by a plus sign.

Answer:

This is not a function.

Step-by-step explanation:

A function by definition will map one element of the domain to one element of the range.  In this example, we would need one element of A to match one element of B for all elements of A.

Note, there are two elements in set A that map to one element in set B, while one element in set B has no mapping from any element in set A.
