Homework . a A man bought for GH¢ 5,500 and sold it for GH & 6,500. Find the Percentage gain.​

Answer:

x = -6

y = -16

Step-by-step explanation:

if you subtract the two equations from each other then the 'y' terms will be eliminated:

 2x = -12

 x = -6

solve for 'y':

4(-6) - 3y = 24

-24 - 3y = 24

-3y = 48

y = -16

You can use the fact that two expressions in equality can be considered to be equal to a third variable(not used in given context).

The system of equations that could be graphed to solve the equation given is

Suppose the equation be [tex]a = b\\[/tex]

Let there is a symbol [tex]c[/tex] such that we have [tex]a = b = c[/tex]

It is because a and b are same measure (that is exactly what a = b means)

and we gave another name c to that measure.

Thus, we have

[tex]a = c\\b = c[/tex]

in addition to  [tex]a = b\\[/tex]

Since the given equation is [tex]log_{0.5}(x) = log_2(2+x)[/tex]

The 2d graphs are usually expressed as [tex]y = f(x)[/tex] on X-Y plane.

Taking the equation's expressions equal to y, we get

[tex]log_{0.5}(x) = log_2(2+x) = y[/tex]

or, we get system of equations as

[tex]y = log_{0.5}(x)\\\\y = log_3{(2 + x)}[/tex]

Their graph is plotted below. The intersection point of both curves is the solution to the given equation as it satisfies both the equations of the system of equations formed from the given equation.

Thus,

Answer:

y= 2x +6

Step-by-step explanation:

Slope-intercept form

y= mx +c, where m is the slope and c is the y-intercept.

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

Slope

[tex] = \frac{6 - ( - 2)}{0 - ( - 4)} [/tex]

[tex] = \frac{6 + 2}{0 + 4} [/tex]

[tex] = \frac{8}{4} [/tex]

= 2

y= 2x +c

y-intercept occurs at x= 0. Since we are given that the line passes through the coordinates (0, 6), the y-intercept is 6.

Thus, the equation of the line is y= 2x +6.

Chapter: States of Matter

Ans: Increases ( option a ).

Why ?

Explanation: As when the matter goes from solid to liquid, the process is done by gaining heat energy which results a transformation phase known as melting. Due to this, the particles in solid gain enough kinetic energy which starts random collision with each other, hence causes the expansion of intermolecular spaces.

Answer:

[tex]x^2 + 12x +36 = (x+6)^2[/tex]

Step-by-step explanation:

[tex]x^{2} + 12x +36\\\\\\Step 1: Find\ factors \ of\ 36\ that \ add \ to \ +12.\\(1, 36)\ , \ ( 2, 18), \ (3, 12), \ (4, 9), \ (6, 6)\\\\Step2. \ From \ the \ pairs \ above \ (6 , 6) \ adds \ to \ +12.\\\\So \ the \ equation \ can\ be \ written \ as \\x^{2} + 6x +6x +36 = (x^{2} + 6x) + (6x + 36)[/tex]

                          [tex]= x(x + 6) + 6(x+6)\\\\=(x+6)(x+6)\\\\=(x+6)^2[/tex]

Answer:

Step-by-step explanation:

a²+ 2ab + b² = (a +b)²

x² + 12x + 36  = x² + 2 * x * 6 + 6²        {Here a = x and b = 6}

                         = (x + 6)²

Answer:

1:5

Step-by-step explanation:

To write 4: 20 in simplest form we have to find the GCF (Greatest common factor)

The GCF of 4 and 20 is 4.

we need to factor each number

(factors of 4 = 1, 2, 4)

(factors of 20 = 1, 2, 4, 5, 10, 20)

and choose the greatest factor that exactly divides both 4 and 20, i.e., 4.

Now we can divide

4: 4 = 1

20 : 4 = 5

Thus, 4: 20 in simplest form is 1:5

[RevyBreeze]

Answer:

1:5

Step-by-step explanation:

4:20 also can be express as 4/20 {fraction}

Find GCF : 4

Thus,

4/4 = 1

20/4 = 5

we can also see that if we cross multiply:

4 × 5 = 20

20 × 1 = 20

[tex]\frac{4}{20}=\frac{1}{5}[/tex]

Therefore, 4:20 in the simplest form is 1:5 or 1/5

1600 is the answer because

321×5 = 1605 so estimation = 1605

Answer:

$360

Step-by-step explanation:

El sueldo de la persona es igual a un monto de $360

Si tenemos un número y queremos determinar una fracción de este entonces debemos multiplicar la fracción por el número recordando que en la multiplicación de fracciones se obtiene una fracción con numerador la multiplicación de los numeradores y con denominador la multiplicación de los denominadores (si es solo un número entero su numerador es el entero y su denominador es 1), luego se simplifica de manera de obtener una fracción irreductible (fracción donde el numerador y el denominador no tengan términos en común)

Los 7/9 del sueldo es $280, entonces si el sueldo es "x" tenemos que:

7/9*x = $280

x = $280*9/7 = $2520/7

x = $360

Answer:

Step-by-step explanation:

y=4 times 1/2 to the power of x can be written symbolically as

                                                             4                  4

y = 4(1/2)^x.  This is the same as y = ------- or y = -------- * 2^(-x)

                                                             2^x                1

This function is a "decaying exponential."

A suitable table follows:

x      4(2^[-x])         x    y

0      4(2^0)           (0, 4)

1        4(2^1)            (1, 8)

2       4(2^2)           (2, 16)

and so on.

Answer:

5:46pm

Step-by-step explanation:

6:32 - :46 =

6:00 = :46 - :32 = :14

6:00 = 5:60

5:60 - :14 = :60 - :14 = :46

5:46

This is NOT a function.

For a relation to be a function, each x-value needs to have only 1 y-value. This is not the case for the data points given here. The x-value 160 has 7 different y-values. If these points were graphed, it would form a straight line and a straight line is not a function (it does not pass the vertical line test!).

Hope this helps!

Answer:

7:56 A.M.

Step-by-step explanation:

1 hour and 59 mins = 119 mins

119+18 = 137

137/60 = 2 r 17

(10 - 2 = 8) - 17/60

Therefore they left at 7:56 A.M.
