Answer:

x=6

Step-by-step explanation:

3(x-2)=12

divide both sides by 3

x-2=4

add 2 to both sides

x-2+2=4+2

combine like terms

x=6

Answer:

x = 6

Step-by-step explanation:

So the equation looks like this:

3(x - 2) = 12

So the first thing we are going to do in this equation is multiply 3 by x and -2 in order to get rid of the parenthesis:

3(x - 2) = 12

(3 * x) + (3 * (-2)) = 12

3x - 6 = 12

Now we are going to add 6 to -6 and what you to one side of the equation you do to the other:

3x - 6 = 12

    + 6  + 6

3x = 18

Now in order to segregate the variable x from 3 we are going to have to divide 3x by 3 and what you do to one side of the equation you do to the other:

3x/3 = 18/3

x = 6

Now in order to check our work we are going to replace the variable x with six in the equation:

3(x - 2) = 12 = 3((6) - 2) = 12

(3 * 6) + (-2 * 3) = 12

18 - 6 = 12

12 = 12

Tada, hope this helps you!!

Answer:

20/20

Step-by-step explanation:

Given:

The relations in the options.

To find:

The relation which is a function.

Solution:

Consider the options are :

(a) {(2, 7), (6, 5), (4, 4), (3, 3), (2, 1)}

(b) {(9, −3), (9, 3), (4, −2), (4, 2), (0, 0)}

(c) {(1, 0), (3, 0), (1, 1), (3, 1) (1, 3)}

(d) {(1, 1), (2, 2), (3, 3), (4, 4), (5, 8)}

A relation is a function if there exist a unique y-value for each x-value.

In option (a), y=7 and y=1 at x=2. So, it is not a function.

In option (b), y=-3 and y=3 at x=9. So, it is not a function.

In option (c), y=0 and y=1 at x=3. So, it is not a function.

In option (d), there are unique y-value for each x-value. So, it is a function.

Therefore, the correct option is (d).

Step-by-step explanation:

42/13=4

Answer:

1/26

Step-by-step explanation:

-4/13 is equivalent to -8/26. Since 9/26 and -8/26 have the same denominator, you can add together the numerator to get the numerator of the final answer. 9-8 is 1, so your answer is 1/26.

Answer: When a point or figure on a coordinate plane is moved by sliding it to the right or left or up or down, the movement is called a translation. The figure is translated from one position to another. Example 1: A point is located at (3, 7) on the coordinate plane. In geometry, a translation is the shifting of a figure from one place to another without rotating, reflecting, or changing its size. This is done by moving the vertices of the figure to the prescribed number of spaces on a coordinate plane and then drawing the new figure. There are four main types of transformations: translation, rotation, reflection, and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage.

Step-by-step explanation:

two of the triangles' corresponding angles are the same even if the side lebgths are not, making these two similar

By AA similarity triangle ABC and triangle LMN are similar. Therefore, option A is the correct answer.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

In the given triangle ABC, ∠A=50° and ∠B=75°.

In the given triangle LMN, ∠L=50° and ∠M=75°

From the given triangles,

∠A=∠L=50°

∠B=∠M=75°

By AA similarity triangle ABC and triangle LMN are similar.

Therefore, option A is the correct answer.

Cost price of vehicle=  $25,599

Selling price of vehicle= $22,000

Required

The percentage discount in the price

Step two:

% discount= cost price-selling price/cost price*100

% discount= 25,599-22,000/25,599*100

% discount= 3599/25,599*100

Answer:

The equation which correctly relates x and y is y = 4x

Step-by-step explanation:

The equation of the direct variation is y = k x, where

∵ The variables x and y vary directly

→ Use the form of the equation above

∴ y = k x

∵ When x = 13, y = 52

→ That means the initial values of x and y are 13 and 52

∴ x = 13 and y = 52

→ Substitute them in the equation above to find k

∵ 52 = k (13)

∴ 52 = 13k

→ Divide both sides by 13

∴ 4 = k

∴ The value of k is 4

→ Substitute it in the equation

∴ y = 4x

∴ The equation which correctly relates x and y is y = 4x

HL

Step-by-step explanation:

The hypotenuse and the "leg" are congruent...along with the 90 degree angle.

"The HL Postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent." - Calcworkshop

Answer:B?

Step-by-step explanation:

The two triangles are congruent by SAS, not the HL theorem. Therefore, the correct answer is option A.

Triangle DEG and triangle EFG are right triangles.

The figure shows DE=EF (Given)

EG=EG by the reflexive property.

Therefore, by the HL theorem, Triangle DEG and triangle EFG are congruent.

Here, Mohamed stated postulate wrong.

By SAS postulate, Triangle DEG and triangle EFG are congruent.

Answer

The  value is  [tex]P = 131.07[/tex]

Step -by -step -explanation :

 From the question we are old that

         The sample size is  n =  20  

         The sample mean for the first person of each twin is  [tex]\= x = 100.45[/tex]

         The sample mean for the second person of each twin is  [tex]\= y = 103[/tex]

          The  correlation between both data is  r =  0.908

         The p-value is  p-value  =  0.000

          The  equation  [tex]\^ y = 13.47 + 1.12 x[/tex]

Here we are told that x represents  the first person to be given birth to among each twin  

       The value of x  considered is  x = 105

          Generally given that p-value  =  0.000

Then  the  Predicted value of  [tex]\^ y[/tex]  is mathematically represented as

           [tex]P = 13.47 + 1.12 (105)[/tex]

=>         [tex]P = 131.07[/tex]

Complete Question

A contestant in a game show has​ 9,000 points. The contestant answers the next question incorrectly and loses 750 points. Does the word​ "lose" suggest a positive integer or a negative​ integer? What integer represents a loss of 750​ points?

a) Positive, + 750

b) Positive , - 750

c) Negative , +750

d) Negative , - 750

Answer:

d) Negative , - 750

Step-by-step explanation:

We are told in the question that the contestant has 9000 points

Then he loses 750 points.

This means that the 750 points would be deducted from the 9000 points he the contestant has already.

The word lose is a negative and it carries the Subtraction (-) sign,

hence, lose suggests a negative integer which is given as:

-750

Answer:

x = 8

Step-by-step explanation:

Interior angles of a triangle always add up to 180 degrees.

50 + 76 + ? = 180

? = 180 - 126

? = 54

A straight line also is always 180 degrees.

54 + 15x + 6 = 180

15x = 180 - 60

15x = 120

x = 8
