Step-by-step explanation:

Reduce the expression, if possible, by cancelling the common factors. Hope this helps! <3

The given function is expressed as

y = (6x + 12)/2

In order to determine the inverse of the given function, we would substitute x for y and y for x. Then we would solve for y. It becomes

x = (6y + 12)/2

x = 3y + 6

3y = x - 6

y = (x - 6)/3

y = x/3 - 2

The inverse is

y = x/3 - 2

whenever you have an equation with one variable on both sides, you might end up with one of the following case:

1. You might end up with an inconsistent equation, therefore there is not solution. Example

x = x+3. If you subtract x on both sides, you get 0=3 which is impossible.

2. You might end up having infinite solutions. Example:

x+6 = x+6. If you subtract x on both sides you get 6 =6 which is true regardless of the value of x.

3. You might end up having only one solution. Example:

3x +2 = x +5

If you subtract x on both sides and subtract 2 on both sides, you get

2x = 3.

then if you divide by two on both sides, you find

x = 3/2. So this equation has one unique solution.

Step-by-step explanation:

the treaty for defeated Germany was Article 231, commonly known as the "War Guilt Clause," which forced the German nation to accept complete responsibility for initiating World War I. Germany was required to make enormous reparation payments

The values of x and y will be 100° and 10° when two parallel lines are being cut by a transversal line.

According to the question,

We have a figure where two parallel lines are being cut by a transversal line.

Now, we know that the angles formed on a straight line is 180° and vertically opposite angles are equal.

The sum of consecutive interior angles is 180°.

Now, we will use these three statements in finding the values of x and y.

Now, adding (2x-70)° and (5y)° will give 180° because the angles made are on a straight line.

(2x-70)°+(5y)° = 180°

2x+5y = (180+70)°

2x+5y = 250° .... (1)

Now, (x+30)° will be the interior angle consecutive to 5y° because they are vertically opposite angles.

So, we have:

(x+30)°+5y° = 180°

x+5y = (180-30)°

x+5y = 150°

5y = 150-x

Now, putting this value of 5y in equation 1:

2x+5y = 250

2x+150-x = 250

x+150 = 250

x = (250-150)°

x = 100°

Now, we will find the value of y:

5y = 150-x

5y = 150-100

5y = 50

y = 50/5

y = 10°

(Note that the values of x and y will be in ° because angles are measured in degree.)

Hence, the value of x is 100° and the value of y is 10°.

Total number of students is,

Now we find the degrees to indicate the region A. we get,

So the required soluion is 53.29 degrees.

Answer: 126°

Step-by-step explanation:

Step-by-step explanation: Since every triangle has 180 interior degrees, we can say 2x + 3x + 90° = 180°. Subtract 90° from each side and we get

2x + 3x = 90°

5x = 90°

x = 18°

Plug in x for Angle 2, giving us Angle 2 = 54°

Angle 1 and angle 2 must add up to 180°

Subtract 54° from 180° and we get 126°

Answer:

C 700

Step-by-step explanation:

7271 is close to 7000

12 is close to 10

So 7000/10 = 700

0. From the given graph, the cumulative frequency value indicates the number of students, we have 100 total number of students .

• so,Median is half of the students = 100/2 = 50

the value of test score that corresponds with 50 = 55 test score

• This means that the median , 50 students scored 55 % in the exa,m.

2. Finding the lower quartile Q1 :

since we have 100 students , 100/4 = 25, so Q1 = 25

the value that corresponds with cumulative frequency of 25 = 45

• This means that 25 students scores 45 %

3. Finding the Interquartile range :

IQR = Upper Quartile -Lower Quartile

Upper quartile = Q3 = 75 students : 60 %

and lower quartile = 45%

So,

IQR = 60-45

= 15

• This means that 15 students got 35 %

Step-by-step explanation:

Jenny's age is 20 years, Lynn is 14 years and Kim is 23 years.

Let's take Jenny as J, Kim as K and, Lynn as L.

From the given statement we get the equation.

As the sum of the age of the three sisters is 57. So we have an equation,

J + K + L = 57 ........(i)

Jenny is 6 years older than Lynn. So the next equation is,

J = 6 + L .......(ii)

Kim is 5 years less than twice her age Lynn. So the equation is,

K = 2L -5 .........(iii)

Putting equations (ii) and (iii) in equation (i)

6 +L + 2L - 5 + L = 57

4L = 56

L = 14

Put the value of L in equations (ii) and (iii)

J = 6 + 14

 = 20

K = 2(14) -5

   = 28 - 5

   = 23

Therefore the age of Jenny is 20 years, Lynn is 14 years and Kim is 23 years.

Equation of 'm'

(y - 6) = - ³/₅ (x - 2)     [point-slope form]

y = - ³/₅ x + ³⁶/₅    [slope-intercept form]

Equation of 'q'

(y - 6) = ⁵/₃ (x - 2)         [point-slope form]

y = ⁵/₃ x + ⁸/₃         [slope-intercept form]

To find the equation for both 'm' and 'q' requires a bit of work. Because neither  'm' nor 'q' has two points to find the slopes of the line, we have to get creative.

The Line 'n' has two points [ (4, 4) & (1, -1) ], and as such we can find the slope of that line. The line 'n' is parallel with 'q' and perpendicular with m.

For finding the slope of 'n'

The slope of the 'n'    =  (y₂ - y₁) ÷ (x₂ - x₁)      

=  (4 - (- 1)) ÷ (4 - 1)  

=  5 ÷ 3

=  ⁵/₃

To estimate the slope of 'q' and 'm'

When two lines exists parallel, they contain the exact slope.

Since 'n' and 'q' exists parallel,

then the slope of q = ⁵/₃

When two lines exists perpendicular, the product of their slopes exists -1. This means that the slopes exists negative-reciprocals of each other.  

Since 'n' and 'm' exists perpendicular

then the slope of m = - ³/₅

Write the equation for 'q' and 'm'

We can now utilize the point-slope form (y - y₁) = m(x - x₁)) to write the equation for the lines

For both 'q' and 'm' let (x₁, y₁) be (2, 6)

Equation of 'm'

(y - 6) = - ³/₅ (x - 2)     [point-slope form]

y = - ³/₅ x + ³⁶/₅    [slope-intercept form]

Equation of 'q'

(y - 6) = ⁵/₃ (x - 2)         [point-slope form]

y = ⁵/₃ x + ⁸/₃         [slope-intercept form]

The linear equation parallel to y = 3x - 2 that passes through the point (4, 6) is:

y = 3*x - 6

Here we want to find a linear equation parallel to:

y = 3x - 2

Now, a general linear equation is:

y = m*x + b

Where m is the slope and b is the y-intercept.

Remember that two lines are parallel if and only if the lines have the same slope and different y-intercept.

So our linear equation will be something like:

y = 3*x + c

Now we also want our line to pass through the point (4, 6), then we can replace these values:

6 = 3*4 + c

6 = 12 + c

6 - 12 = c

-6 = c

So the linear equation is:
