Answer:

Missing value is -4/3 and whole solution can be written as  ( 8,-4/3)

Step-by-step explanation:

Given equation 2x+3y=12

solution ( 8,)

solution is form (x,y) hence in (8,) x is given as 8 while y  is missing to find y

we will plug 8 as value of x in equation  2x+3y=12. From this equation we will find the missing value.

2x+3y=12

=> 2*8+3y=12

=> 16 + 3y = 12

=> 3y = 12-16= -4

=> y = -4/3

Thus, missing value is -4/3 and whole solution can be written as  ( 8,-4/3)

Answer:

x = 24.

Step-by-step explanation: given lines s and t are parallel and line m is a bisector, we can conclude that (2x+27) is an opposite exterior angle and congruent to the angle adjacent to (4x+9).  Defining those 2 angles are supplementary, they = 180 degrees.  Therefore, 2x+27+4x+9=180.  Subtract 36 (27+9) from the left side of the equation as well as from the right side (180-36) you get 2x+4x=144.  Add the x's you get 6x.  So, 6x=144.  Divide both sides by 6 and you get x=24.

Hope that helps

answer is 24

Step-by-step explanation:

Answer:

w⁴ - 36

=> ( w² )² - ( 6 )²

=> ( w² + 6 ) ( w² - 6 )

=> w² + 6 = 0 and w² - 6 = 0

=> w = √-6 and w = √6

The value of w is √-6 and √6 .

An identity is an equation that is true for all values of the variables.

For example:

The above equation is true for all possible values of x and y, so it is called an identity.

According to question one such identity will be used

[tex]a^{2} - b^{2} = (a+b)(a-b)[/tex]

w⁴ - 36

= ( w² )² - ( 6 )²

= ( w² + 6 ) ( w² - 6 )

= w² + 6 = 0 and w² - 6 = 0

= w = √-6 and w = √6

Hence, w is a quadratic term so it have two value √-6 , √6 .

Answer:

Im confused on how its wrote down

Step-by-step explanation:

Answer:

The correct option is B. 3√2(cos(135°) + i·sin(135°))

Step-by-step explanation:

The complex number is given as : 3 - 3i

Now, comparing this with the standard for : a + bi

⇒ a = 3 and b = -3

Now, r = √a² + b²

⇒ r = √18

⇒ r = 3√2

Now, The polar form is represented by :

z = r(cosθ + i·sinθ)

⇒ z = 3√2(cos 135° + i·sin 135°)

Therefore, the correct option is B. 3√2(cos(135°) + i·sin(135°))

The sum of the interior angles of a polygon is

sum = (n - 2) 180° ← n is the number of sides → A

The sum of the interior angles of a polygon with n sides is (n - 2) 180°.

The sum of all interior angles of an ordinary polygon is calculated via the method S=(n-2) × 180°, where 'n' is the number of sides of a polygon.

A polygon is a closed-dimensional form this is formed by means of enclosing line segments. not less than 3 line segments are required to make a polygon.

Answer:

D.

Step-by-step explanation:

area of a square = side^2

area of a cube = 6 x side^2

let the side be a .

6a^2 = 600

=> a^2 = 600/6

=> a^2 = 100

Hence the area of one of its faces is 100 square inches.

or in plain terms without using those formulas,

6 faces of the cube have 600 square inches

=> 1 face of the cube has 600/6 = 100 square inches

[tex]k = 3[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 0.5x[/tex]

[tex]g(x) = 0.5x - k[/tex]

Required

[tex]Find\ k[/tex]

Initial expression of f(x) is [tex]f(x) = 0.5x[/tex]

From the question; we understand that f(x) was shifted down by 3 units;

This implies that

[tex]New\ f(x) = 0.5x - 3[/tex]

Also from the question; we understand that this new f(x) is equivalent to g(x);

In other words;

[tex]New\ f(x) = g(x)[/tex]

Substitute[tex]New\ f(x) = 0.5x - 3[/tex] and [tex]g(x) = 0.5x - k[/tex]

This gives

[tex]0.5x - 3 = 0.5x - k[/tex]

Subtract 0.5x to both sides

[tex]0.5x - 3 - 0.5x = 0.5x - k - 0.5x[/tex]

Rearrange

[tex]0.5x - 0.5x - 3 = 0.5x - 0.5x- k[/tex]

[tex]-3 = -k[/tex]

Multiply both sides by -1

[tex]-3 * -1 = -k *-1[/tex]

[tex]3 = k[/tex]

[tex]k = 3[/tex]

the value of x is 2.7.

Answer:

y>1.5x+3

Step-by-step explanation:

All you need to do is isolate y, no coefficients, using basic algebra.

3x-2y<-6

-3x both sides

-2y<-3x-6

divide by -2 and switch the comparing sign to the other direction.

y>1.5x+3

Answer:

y > 3/2x +3

Step-by-step explanation:

3x-2y<-6

Subtract 3x from each side

3x-3x-2y<-3x-6

-2y< -3x-6

Divide each side by -2, remembering to flip the inequality

-2y/-2 > -3/-2x -6/-2

y > 3/2x +3

The angle at which the pizza slices were cut would be 39.75°. The round-off to the nearest whole number would be 40°.

To find out the angle at which the pizza slices were cut, we need to first find out the angle of each slice of the pizza.

As per the question,

The total area of the pizza= 34 square inch

The total angle of the pizza= 360 degrees

We already know the area of a pizza= [tex]\pi r^2[/tex]

[tex]\pi[/tex]= 3.14

The diameter of the pizza, given= 14 inch

Therefore, the radius of the pizza= 7 inch

Area of the pizza= [tex]3.14*7^2[/tex]

=153.94

Now, the angle of the slice can be determined by:

The angle of the slices= (Area of each slice/Area of the pizza)* Total angle

The angle of the slices= (34/153.94)*360

=79.51

Since you ate 2 slices,

the angle of one slice = 79.51/2

=39.75 or the round-off would be 40.

Therefore, the angle at which the pizza slices were cut is 40°.
