Answer:1+3=4 4+2=6 5+6=11

Step-by-step explanation:

Answer:

1+3=4, 2+4=6, 5+6=11

Step-by-step explanation:

when made into a cube, (assuming 2 is on the top,) 1 is on the left side and 3 is on the right. 2 is on the top and 4 is on the bottom. 5 is on the north side (the front I guess, but north is the way I can explain it best) and 6 is on the south (the back).

hello :

2x+7y=1 ...(*)

y=4x−8...(**)

(4;8) means x= 4 and y= 8

put this values in (*) and(**) :

2(4)+7(8) =1           62=1    false

8=4(4)-8          8=8   true

so :(4;8)  is not solution for this system.

Answer:

x = 18

y = 54

Step-by-step explanation:

90 - 72 = 18

18 + 2x = 3x

18 = x

2(18) = 36

3(18) = 54

72 + y + 54 = 180

126 + y = 180

y = 54

Step-by-step explanation:

the graph has a y intercept of (0, -4) and a slope of 3

the equation is y = 3x - 4

Answer:

Step-by-step explanation:

tan 26° = [tex]\frac{x}{90}[/tex] ⇒ x = 90tan26° ≈ 43.9 ft. (This answer for the picture)

sin 26° = [tex]\frac{h}{100}[/tex] ⇒ h = 100sin26° ≈ 43.9 ft (This answer for the text)

h = √(100² - 90²) ≈ 43.589 ft. (Pythagorean theorem)

Answer:

Price is $1088 (agrees with answer B)

Step-by-step explanation:

Notice that the linear equation that represents this relationship can be estimated via finding the slope and y-intercept using a couple of the given points on the plane (for example (5, 140), and (10, 200), which results in;

Price = 12 x + 80

where "x" is the number of computers shipped.

Then, to ship 84 computers, we have the following price:

Price = 12 (84) + 80 = 1088

Then the price is $1088.

Answer:

b = 7

Step-by-step explanation:

Add 4b to both sides

You then get -b = -7

You want to multiply both sides by -1 because you can't have a negative variable

x ≤ -2    OR  x ≥ 4

__________________________________________________________

We are given the inequality:

|2x - 2| ≥ 6

Getting rid of the Modulus:

Since 2x-2 is in modulus:

|2x-2| =  -(2x-2)    OR   2x-2

(since the modulus of both these values is 2x-2)

Hence, our inequality can be written in 2 different ways:

__________________________________________________________

Solving these 2 inequalities:

Solving inequality 1:

2x - 2 ≥ 6                

2x ≥ 8                     [adding 2 on both sides]

x ≥ 4                       [dividing both the sides by 2]

This is the solution of the inequality if: 2x-2 ≥ 0

Solving Inequality 2:

-(2x-2) ≥ 6

It can be rewritten as:

2 - 2x ≥ 6                

2 ≥ 6 + 2x                [adding 2x on both the sides]  

-4 ≥ 2x                     [Subtracting 6 from both sides]

x ≤ -2                       [Dividing both sides by 2]

This is the solution of the given inequality if: 2x-2 < 0

__________________________________________________________

Solution of the given Inequality:

Therefore, the solution of the given inequality |2x-2| ≥ 6 are:

x ≥ 4   (if 2x-2 ≥ 0)

x ≤ -2  (if 2x-2 < 0)

Hence, option C is correct!

Answer: 61

Step-by-step explanation:

[tex]\sqrt{x+20}=9\\\\x+20=81\\\\x=\boxed{61}[/tex]

The value of x will be 61.

What is mathematical expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The mathematical expression is,

⇒ √x + 20 = 9

Now,

Solve the expression for the value of x as;

The mathematical expression is,

⇒ √x + 20 = 9

Take square on both side, we get;

⇒ (√x + 20 )² = 9²

⇒ x + 20 = 81

Subtract 20 both side, we get;

⇒ x + 20 - 20 = 81 - 20

⇒ x = 61

Therefore, The value of x will be 61.

Answer:

  12 units

Step-by-step explanation:

Reflection over two lines x units apart is equivalent to a translation of 2x units. Since the given lines are 6 units apart, ...

  the equivalent translation is of 12 units.

___

Example:

Lines at x=0 and x=6. Point (x, 0). After reflection over x=0, the point is located at (2·0 -(x), 0) = (-x, 0). After reflection of that over x=6, the point is located at (2·6 -(-x), 0) = (12 +x, 0). That is, 12 has been added to the x-coordinate, meaning the point was translated 12 units. (The translation is in the direction the second line is from the first.)

Answer:

1681

Step-by-step explanation:

In a four digit perfect square, the first two digits and last two digits taken seperately are also perfect squares.

Therefore, the answer is 1681 because 1681=41*41 and

16=4*4 and 81=9*9

Answer:

The domain of the graph must be [tex]x\ge \:-4[/tex].

Therefore,

[tex]x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]

Hence, option a is true.

Step-by-step explanation:

From the graph, it is clear that the graph is heading towards positive infinity from x=-4.

The point x=-4 is included in the graph as the starting point of the graph i.e. x=4 is showing a closed circle on x=4, and heading towards positive infinity onward.

i.e. [-4, ∞)

Hence, the domain of the graph must be [tex]x\ge \:-4[/tex].

Therefore,

[tex]x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]

Hence, option a is true.
