Answer:

x = 3, y = - 2

Step-by-step explanation:

Simplify the 2 given equations

3(x + 1) - 5(y + 2) = 12 ← distribute left side

3x + 3 - 5y - 10 = 12

3x - 5y - 7 = 12 ( add 7 to both sides )

3x - 5y = 19 → (1)

----------------------------------

5(- 3 + 2x) - 3(4 - y) = - 3 ← distribute left side

- 15 + 10x - 12 + 3y = - 3

10x + 3y - 27 = - 3 ( add 27 to both sides )

10x + 3y = 24 → (2)

-------------------------------------------

Solve the 2 equations simultaneously

3x - 5y = 19 → (1)

10x + 3y = 24 → (2)

Multiplying (1) by 3 and (2) by 5 and adding the result will eliminate y

9x - 15y = 57 → (3)

50x + 15y = 120 → (4)

Add (3) and (4) term by term to eliminate y

59x = 177 ( divide both sides by 59 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

3(3) - 5y = 19

9 - 5y = 19 ( subtract 9 from both sides )

- 5y = 10 ( divide both sides by - 5 )

y = - 2

Solution is x = 3, y = - 2

Answer:

1/2h+9=17

We move all terms to the left:

1/2h+9-(17)=0

Domain of the equation: 2h!=0

h!=0/2

h!=0

h∈R

We add all the numbers together, and all the variables

1/2h-8=0

We multiply all the terms by the denominator

-8*2h+1=0

Wy multiply elements

-16h+1=0

We move all terms containing h to the left, all other terms to the right

-16h=-1

h=-1/-16

h=1/16

Answer:

C

Step-by-step explanation:

There is a difference of 16 between consecutive terms, that is

259 - 243 = 275 - 259 = 291 - 275 = 16

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 243 and d = 16 , then

[tex]a_{n}[/tex] = 243 + 16(n - 1) = 243 + 16n - 16 = 227 + 16n → C

Answer:

y = 8x+9

Step-by-step explanation:

First find the slope

m = (y2-y1)/(x2-x1)

  = ( 57-17)/(6-1)

   = 40/5

  = 8

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

y = 8x+b

Substitute a point into the equation

33 = 8*3 +b

33 = 24+b

Subtract 24 from each side

33-24 = 24+b-b

9 = b

y = 8x+9

#equation

Slope

Now

On comparing to slope intercept form

y intercept is 9

Answer:

672 feets

Step-by-step explanation:

Using the solution diagram attached, the vertical height, h of the lighthouse ;

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 2 = h / 804

h = tan 2 * 804

h = 28.076 feets

Using h, we can obtain the distance CB :

Tan θ = opposite / Adjacent

Tan 2 = 28.076 / CB

CB = 28.076 / Tan 12°

CB = 132.08860 feets

Distance between A and B

804 - 132.08860

= 671.9 feets

Answer:250 ft

Step-by-step explanation:

Based on the table, a possible taxable income for a taxpayer filing with the Single filing status is $50,000.

Taxation can be defined as the involuntary (compulsory) fees that are levied on individuals or business firms by the government of a particular country, so as to generate revenues that can be used to fund public institutions and activities.

Based on the table, the range of income for a married couple that is filing singly in the 25% federal income tax bracket is $33,950 to $82,250.

This ultimately implies that, a possible taxable income for a taxpayer filing with the Single filing status is $50,000.

Answer:

She walked for 46 minutes

Step-by-step explanation:

Given

When she leaves home

[tex]h = 7am[/tex]

[tex]\theta_1 = 110^o[/tex]

When she arrives at school

[tex]H = 8am[/tex]

[tex]\theta_2 = 110^o[/tex]

Required

Time to walk to school

First, we convert [tex]\theta_1 = 110^o[/tex] to minutes:

[tex]\theta_1 = \frac{110}{6}[/tex]

[tex]\theta_1 = 18.33[/tex]

[tex]\theta_1 = 18[/tex] --- approximated

From the question, we understand that she left home past 7.

This means that the difference between the hour hand (at 7) and the minutes hand is 18 minutes.

Also, the minute hand is between 0 and 30 minutes

Subtract 18 minutes from 30 minutes;

[tex]Mins = 30-18=12[/tex]

She left home at 7:12am

Similarly;

[tex]\theta_2 = \theta_1 = 18\ mins[/tex]

From the question, we understand that she arrived before 8.

This means that the difference between the hour hand (at 8) and the minutes hand is 18 minutes

Also, the minute hand is between 30 and 60 minutes mark.

At the 8hour hand, the minutes is 40

Add 18 minutes from 40 minutes;

[tex]Mins = 40 + 18 = 58[/tex]

She arrived at 7:58am

The difference (d) is:

[tex]d =7:58am - 7:12am[/tex]

[tex]d =46[/tex]

Answer: labor force participation rate  =60%

unemployment rate = 6.67%

Step-by-step explanation:

The labor force participation rate is computed as

[tex]\text{labor force participation rate}=\dfrac{\text{Total employed persons}}{\text{Total population}}[/tex]

i.e. [tex]\text{labor force participation rate}= \dfrac{72000}{120000}[/tex]

[tex]= 0.6\ or\ 60 \%[/tex]

The unemployment rate is computed as:

[tex]\text{unemployment rate}=\dfrac{\text{Number of personsdon't have jobs }}{\text{Total population}}\\\\\text{unemployment rate}=\dfrac{8000}{120000}\\\\\text{unemployment rate}=0.0667\ or\ 6.67\%[/tex]

Hence, labor force participation rate  =60%

unemployment rate = 6.67%

Answer:

x = 2, HJ = JK = 11

Step-by-step explanation:

Given that H is the midpoint of JK , then

HJ = JK = 6x - 1 and

HJ + JK = JK , that is

6x - 1 + 6x - 1 = 3x + 16 ← simplify left side

12x - 2 = 3x + 16 ( subtract 3x from both sides )

9x - 2 = 16 ( add 2 to both sides )

9x = 18 ( divide both sides by 9 )

x = 2

Then

HJ = JK = 6x - 1 = 6(2) - 1 = 12 - 1 = 11

Answer:

Below

Step-by-step explanation:

The area of a circle is given by A=πr². Since we know the radius, we can sub r with 11.

This gives A=11²π, which by solving the square gives A=121π.

From there, you would solve with a calculator by typing 121×π, giving a final area of 380.132711084.

Answer:

  B, C, D, E

Step-by-step explanation:

A square has all side equal, opposite sides parallel, and all angles equal (90°). Because all sides are equal, so are adjacent sides. All but the first and last descriptions apply to a square.

The first description is that of a trapezoid, which has exactly one pair or parallel sides. The last description is that of an isosceles (right) triangle, which has sides that are referred to as "legs."

Undefined slope is when a line becomes vertical. Vertical lines have undefined slope because if we attempt to find the slope using formula, the denominator will become 0 which is undefined.

Next, the equation of a vertical line is x = a where a is any real numbers.

Since the line is vertical, for any a-value would have same y-value which is all real numbers.

However since the graph passes through x = 3. For x = 3 has y-value as set of all real numbers.

Step-by-step explanation:

subtract 3 set equation to zero then do quadratic formula break it down then you 2 square root of 10 over 2 divide to get square root of 10 by itself 2 divided by 2 is 1 therefore leaves 1 ^^.

Step-by-step explanation:

Note that the denominators in the expression are perfect squares:

[tex] {x}^{2} - 5xy + 6 {y}^{2} = (x - 2y)(x - 3y)[/tex]

[tex] {x}^{2} - 4xy + 3 {y}^{2} = (x - y)(x - 3y)[/tex]

[tex] {x}^{2} - 3xy + 2 {y}^{2} = (x - y)(x - 2y)[/tex]

We can then write the given expression as

[tex] \frac{1}{ {x}^{2} - 5xy + 6 {y}^{2} } + \frac{a}{{x}^{2} - 4xy + 3{y}^{2} } + \frac{1}{{x}^{2} - 3xy + 2{y}^{2}}[/tex]

[tex] \frac{1}{ {x}^{2} - 5xy + 6 {y}^{2} } + \frac{a}{{x}^{2} - 4xy + 3{y}^{2} } + \frac{1}{{x}^{2} - 3xy + 2{y}^{2}}[/tex]

[tex] = \frac{1}{(x - 2y)(x - 3y)} + \frac{a}{(x - y)(x - 3y)} + \frac{1}{(x - y)(x - 2y)}[/tex]

[tex] = \frac{(x - y)(x - 2y) {(x -3y)}^{2} + a {(x - y)}^{2} (x - 2y)(x - 3y) + (x - y){(x - 2y)}^{2}(x - 3y) }{ {(x - y)}^{2} {(x - 2y)}^{2} {(x - 3y)}^{2} } [/tex]
