Answer:

400 lira

Step-by-step explanation:

Yukarıdaki sorudan şunu söyleriz: Bir satıcı, sattığı her ürün için satış fiyatının 2 / 9'u kadar kar eder.

Dolayısıyla 1800 liraya televizyon satarsa ​​o televizyondan elde ettiği kâr şöyle hesaplanır:

2/9 × 1800 lira

= 400 lira

Examine the system of equations. y = 3 2 x − 6, y = −9 2 x + 21 Use substitution to solve the system of equations. What is the v
nadezda [96]

Answer:

<h2>y = -4/9</h2>

Step-by-step explanation:

Given the system of equations y = 3/2 x − 6, y = −9/2 x + 21, since both expressions are functions of y, we will equate both of them to find the variable x;

3/2 x − 6 = −9/2 x + 21,

Cross multiplying;

3(2x+21) = -9(2x-6)

6x+63 = -18x+54

collecting the like terms;

6x+18x = 54-63

24x = -9

x = -9/24

x = -3/8

To get the value of y, we will substitute x = -3/8 into any of the given equation. Using the first equation;

y = 3/2x-6

y = 3/{2(-3/8)-6}

y = 3/{(-3/4-6)}

y = 3/{(-3-24)/4}

y = 3/(-27/4)

y = 3 * -4/27

y = -4/9

Hence, the value of y is -4/9

A surveyor wants to find the distance from points A and B to an inaccessible point C. These three points form a triangle. Becaus
harkovskaia [24]

Answer:

Part a) AC=135.95\ m

Part b) BC=124.14\ m

The diagram in the attached figure

Step-by-step explanation:

step 1

Find the measure of angle C

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

m\angle A+m\angle B+m\angle C=180^o

substitute the given values

53^o+61^o+m\angle C=180^o

114^o+m\angle C=180^o

m\angle C=180^o-114^o

m\angle C=66^o

step 2

Find the distance AC

Applying the law of sines

\frac{AB}{sin(C)}=\frac{AC}{sin(B)}

see the attached figure to better understand the problem

substitute the given values

\frac{142}{sin(66^o)}=\frac{AC}{sin(61^o)}

AC=\frac{142}{sin(66^o)}(sin(61^o))

AC=135.95\ m ---> rounded to the nearest hundredth

step 3

Find the distance BC

Applying the law of sines

\frac{AB}{sin(C)}=\frac{BC}{sin(A)}

substitute the given values

\frac{142}{sin(66^o)}=\frac{BC}{sin(53^o)}

BC=\frac{142}{sin(66^o)}(sin(53^o))

BC=124.14\ m ---> rounded to the nearest hundredth

Range of:

6x      +    1

Solution:    [    - ∞    <    f(x)   <    ∞ ]

Interval Notation:   [   (- ∞, ∞) ]


Parity of:

6x     +    1   =====>    Neither  even  nor odd


Axis interception points of:

6x   +   1

x-   Intercepts  ( - 1 / 6,   0 )

y-  Intercepts    ( 0,   1 )


Inverse of:

6x    +   1  =====>    x   -    1 / 6

Slope of:

6x    +   1

Answer:    ======>    m      =         6
