Final answer:

The ordered pair (2,5) satisfies the equation -3x+4y=14, making it the correct solution, while the ordered pair (4,6) does not satisfy the equation.

Explanation:

To determine which ordered pair is a solution to the given linear equation -3x+4y=14, we need to plug in the x and y values from each pair into the equation and see if the equation holds true.

For the ordered pair (2,5), substituting x with 2 and y with 5 gives us:

Since the equation is satisfied, (2,5) is a solution to the equation.

For the ordered pair (4,6), substituting x with 4 and y with 6 gives us:

Since -12 + 24 does not equal 14, the equation is not satisfied, and hence, (4,6) is not a solution to the equation.

Therefore, the correct answer is A- Only (2,5)

Answer:

x = 7

Step-by-step explanation:

The inscribed angle (5x - 3) is equal to half the measure of the intercepted arc

5x - 3 = 0.5(9x + 1) ← multiply both sides by 2

10x - 6 = 9x + 1 ( subtract 9x from both sides )

x - 6 = 1 ( add 6 to both sides )

x = 7

If the markup price of the shoes is $192.61 then the original price of the shoes will be equal to $25.04.

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

As per the given information in the question,

Let the original price of the shoes is x.

Markup Price = $192.61, which is 87% more than the original price.

Price markup = 192.61 × 87/100 = $167.57

Original Price, x = $192.61 - $167.57

x = $25.04.

The standard form of the line with an x-intercept of 6 and a y-intercept of 5 is -5x + 6y = 30.

The standard form of a linear equation is given by the equation Ax + By = C, where A, B, and C are real numbers and A and B are not both zero. To find the standard form of the line with an x-intercept of 6 and a y-intercept of 5, we can use the slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept.

First, let's find the slope using the two intercepts. The slope is (y-intercept - x-intercept) / (0 - 6) = (5 - 0) / -6 = -5/6.

Now, we can substitute the slope and the y-intercept into the standard form equation to get: (-5/6)x + y = 5. Multiplying through by 6, we get -5x + 6y = 30. Therefore, the standard form of the line is -5x + 6y = 30.

Step-by-step explanation:

Answer:

The required points of the given line segment  are ( - 7, - 4 ).

Step-by-step explanation:

Given that the line segment AB whose midpoint M is ( - 2, 3 ) and point A is ( 3, 10), then we have to find point B of the line segment AB -

As we know that-

If a line segment AB is with endpoints ( [tex]x_{1}, y_{1}[/tex] ) and  ( [tex]x_{2}, y_{2}[/tex]  )then the mid points M are-  

M = ( [tex]\frac{ x_{1} + x_{2} }{2}[/tex]  , [tex]\frac{ y_{1} + y_{2} }{2}[/tex]  )

Here,

Let A ( 3, 10 ), B ( x, y ) with midpoint M ( - 2, 3 ) -

then by the midpoint formula M are-

( - 2, 3 )  = ( [tex]\frac{ 3 + x}{2}[/tex] , [tex]\frac{ 10 + y}{2}[/tex] )

On comparing x coordinate and y coordinate -

We get,

( [tex]\frac{ 3 + x}{2}[/tex] = - 2  , [tex]\frac{ 10 + y}{2}[/tex] = 3)

( 3 + x = - 4, 10 + y = 6 )

( x = - 4 - 3, y = 6 - 10 )

( x = - 7, y = -4 )

Hence the required points  A are ( - 7, - 4 ).

We can also verify by putting these points into Midpoint formula.

Final answer:

To find the other endpoint of a line segment with a known endpoint (3, 10) and midpoint (-2, 3), use the midpoint formula in reverse to calculate the coordinates, resulting in the other endpoint being (-7, -4).

Explanation:

To find the other endpoint of a line segment when given one endpoint and the midpoint, you can use the midpoint formula in reverse. The midpoint formula in two dimensions is
( (x1+x2)/2, (y1+y2)/2 ), where (x1, y1) and (x2, y2) are the endpoints of the line segment. Given that (3, 10) is one endpoint and (-2, 3) is the midpoint, we can set up equations to find the coordinates of the unknown endpoint (x2, y2).

To find x2, we use the formula for x-coordinate of the midpoint: (-2 + 3)/2 = (x2 + 3)/2. Solving for x2 gives us x2 = -2 - 3 = -7.

To find y2, we use the formula for y-coordinate of the midpoint: (3 + 10)/2 = (y2 + 10)/2. Solving for y2 gives us y2 = 2*3 - 10 = 6 - 10 = -4.

Therefore, the other endpoint of the line segment is (-7, -4).

Answer:

70%

Step-by-step explanation:

69 - 20.70 = 48.3

48.3 / 69 = 0.7

0.7 x 100 = 70

The discount percentage for the JCPenney dress, discounted from an original price of $69.00 to a final price of $20.70, is calculated to be 70% off.

To calculate the discount percentage for the JCPenney dress, we need to find the difference between the original price and the final price, and then divide that by the original price. We can then multiply the result by 100 to get the percentage.

The original price of the dress is $69.00, and the final price is $20.70. The difference between these two prices is $69.00 - $20.70 = $48.30. This is the amount of the discount.

To find the discount percentage, we divide the discount amount by the original price: $48.30 / $69.00 = 0.7. To convert this decimal to a percentage, we multiply by 100: 0.7  imes 100 = 70%.

Thus, the dress is discounted by 70%.

Answer:

slope: 2/3

y intercept: - 2

x-0,3

y - 3 0

Answer:

graph C

Step-by-step explanation:

Answer:

Step-by-step explanation:

first we need to find the slope using the slope formula :

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

(-9,7)...x1 = -9 and y1 = 7

(-6,-3)....x2 = -6 and y2 = -3

now we sub

slope = (-3 - 7) / (-6 - (-9) = -10 / (-6 + 9) = -10 / 3

so our slope is -10/3

now we use y = mx + b....with m representing the slope

slope(m) = -10/3

use either of ur points....I will use (-9,7)...x = -9 and y = 7

we are solving for b, the y intercept

now we sub

7 = -10/3(-9) + b

7 = 30 + b

7 - 30 = b

- 23 = b

so ur equation is : y = -10/3x - 23

Final answer:

To find the equation of the line through (-9, 7) and (-6, -3), calculate the slope, which is -10/3, and then use the point-slope form to derive the equation y = -10/3 x + 23.

Explanation:

To complete the equation of the line through the points (-9, 7) and (-6, -3), we need to find the slope (m) and use one of the points to find the y-intercept (b) in the slope-intercept form y = mx + b.

Step 1: Find the slope (m):

Step 2: Use point-slope form to find equation:

The completed equation of the line is y = -10/3 x + 23.

If cos x= sin(20 + x)° and 0° < x < 90° then value of x is 35 degrees

Solution:

Given that:

[tex]cos x= sin (20 + x)[/tex]

We know that,

[tex]sin (a+b)=sin a \times cos b+cos a \times sin b[/tex]

[tex]cos x= sin (20 + x) = sin 20 cos x + cos 20 sin x[/tex]

[tex]cos x-sin20 \times cos x=cos 20 \times sin x[/tex]

Taking cos x as common,

[tex]cos x(1-sin 20)=cos 20 \times sin x[/tex]

[tex]\frac{(1-sin 20)}{(cos 20)}=\frac{sin x}{cos x }\\\\tan x = \frac{(1-sin 20)}{(cos 20)}[/tex]

By trignometric functions,

sin 20 = 0.34202

cos 20 = 0.939692

So,

[tex]tan x = \frac{1 - 0.34202}{0.939692}\\\\tan x = 0.7002[/tex]

Therefore,

x = arc tan (0.7002)

x = 35 degrees

Therefore value of x is 35 degrees

cos x = sin (20 + x)

sin and cos are co - functions, which means that:

cos x = cos [90 - (20 + x)]

cos x = cos (90 - 20 - x)

cos x = cos (70 - x)

Therefore, x = 70 - x

x + x = 70

2x = 70

x = 35

Therefore value of x is 35 degrees

The equation is simplified to -x = 5, yet a negative x value indicates that the identity is not true. Hence, there is no solution to this equation.

To solve this equation, we should first try to simplify both sides of the equation.

On the left side, combine like terms. This gives us -6x - 7.

On the right side, we already have -5x - 12.

Setting these expressions equal to each other yields: -6x - 7 = -5x - 12.

Adding 5x to both sides gives us -x - 7 = -12.

Then adding 7 to both sides gives us -x = 5.

However, a negative x value would indicate that the identity is not true, thus the equation has no solution.

Answer:

number of shells zoe gives to dev  = 7

number of shells zoe is left with  = 55-7= 48

number of shells dev has = 9+7=16

Step-by-step explanation:

let the initial number of shells that dev has be A, and initial number of shells that zoe has be B.

let the number of shells that zoe gives to dev be x.

after giiving x shells zoe is left with 3 times the number of shell as that of dev.

therefore number of shells with zoe = 3×number of shells with dev.

number of shells with zoe = initial shells - x = 55-x

number of shells with dev = initial shells + number of shells he gets

                                            = 9+x

therefore (55-x)=3×(9+x)

55-x = 27+3x

55-27=3x+x

4x = 28

x= 7

therefore number of shells zoe gives to dev  = 7

number of shells zoe is left with  = 55-7= 48

number of shells dev has = 9+7=16

2x + 3y = 22

with intercepts (11, 0) and (0, [tex]\frac{22}{3}[/tex])

The solutions to both are below the lines.

Solve 5x + y = 16 and 2x + 3y = 22 simultaneously to find the point of intersection at (2, 6)

The coordinates of the vertices of the feasible region are

(0, 0), (0, 16), (2, 6), 11, 0)

Evaluate the objective function at each vertex

P = 3(0) + 2(0) = 0 + 0 = 0

P = 3(0) + 2(16) = 0 + 32 = 32

P = 3(2) + 2(6) = 6 + 12 = 18

P = 3(11) + 2(0) = 33 + 0 = 33

The maximum value of P is 33 when x = 11 and y = 0
