Answer:

(-4, -1)

Step-by-step explanation:

x = 4y

-4x - y = 17

Plug in 4y for x in the second equation:

-4(4y) - y = 17

Simplify. Remember to follow PEMDAS. Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other.

First, multiply 4y with -4:

-4(4y) = -16y

-16y - y = 17

Simplify. Combine like terms:

-16y - y = 17

-17y = 17

Isolate the variable, y. Divide -17 from both sides:

(-17y)/-17 = (17)/-17

y = 17/-17

y = -1

Plug in -1 for y in the first equation:

x = 4y

x = 4(-1)

x = -4

x = -4, y = -1

Answer: (-4, -1)

Step-by-step explanation:

Any ellipse has the following equ

ation:

[tex] \frac{ {x}^{2} }{ {a}^{2} } + \frac{ {y}^{2} }{ {b}^{2} } = 1[/tex]

where

(as in the picture)

So it should be like:

[tex] \frac{ {x}^{2} }{ { (\frac{6}{2} )}^{2} } + \frac{ {y}^{2} }{ {( \frac{4}{2} )}^{2} } = 1 \\ \frac{ {x}^{2} }{ 9} + \frac{ {y}^{2} }{ 4 } = 1[/tex]

Since it should be moved to the right and up, the answer would be:

[tex]\frac{ {(x - 5)}^{2} }{ 9} + \frac{ {(y - 1)}^{2} }{ 4 } = 1[/tex]

Option D. (x - 5)²/9 + ( y - 1 )²/4 = 1

An ellipse has the following equation:

x²/a² + y²/ b² = 1

where

2b = vertical axis length

2a = horizontal axis length

So it should be like:

x²/(6÷2)² + y²/ (4÷2)² = 1

x²/9 + y²/4 = 1

Since it should be moved to the right and up, the answer would be:

(x - 5)²/9 + ( y - 1 )²/4 = 1

Answer: The equations are as follows;

5p + 4d = 43.25 ————(1) and

3p + 2d = 24.25 ————(2)

Also a bag of popcorn costs $5.25

Step-by-step explanation: We start by assigning letters to the unknown variables. Let a bag of popcorn be p and let one drink be d. The clues given in the question include the cost of buying five bags of popcorn and four drinks which is a total of $43.25. This can be expressed as

5p + 4d = 43.25 ————(1)

Another clue is that three bags of popcorn and two drinks cost $24.25. This also can be expressed as

3p + 2d = 24.25 ————(2)

Now we have a pair of simultaneous equations as follows

5p + 4d = 43.25 ————(1)

3p + 2d = 24.25 ————(2)

We shall use the elimination method since all the unknowns have coefficients greater than 1. Multiply equation one by 3, and multiply equation two by 5 (so as to eliminate ‘p’)

5p + 4d = 43.25 ——— x3

3p + 2d = 24.25 ——— x5

15p + 12d = 129.75 ———(3)

15p + 10d = 121.25 ———(4)

Subtract equation (4) from equation (3) and we have

2d = 8.5

Divide both sides of the equation by 2

d = 4.25.

That means each drink costs $4.25

We can now substitute for the value of d into equation (2)

3p + 2d = 24.25

When d = 4.25

3p + 2(4.25) = 24.25

3p + 8.5 = 24.25

Subtract 8.5 from both sides of the equation

3p = 15.75

Divide both sides of the equation by 3

p = 5.25. This means a bag of popcorn costs $5.25

Step-by-step explanation:

Have a nice day!

Based on the inscribed angle theorem, the measure of arc ECF in circle (G) is equal to: B. 98 degrees.

The inscribed angle theorem states that the measure of an inscribed angle whose vertex lies on a circle is half of the intercepted arc subtended at a point on the circle.

Given the following data:

By using the inscribed angle theorem, we would find the intercepted arc as follows:

∠DEF = ∡DF/2

79 = ∡DF/2

∡DF = 2 × 79

∡DF = 158 degrees.

Now, we can determine measure of arc ECF:

∡ECF + ∡DF + ∡DE = 360

∡ECF + 158 + 104 = 360

∡ECF + 262 = 360

∡ECF = 360 - 262

∡ECF = 98 degrees.

[tex]\frac{9\pi }{5}[/tex] radians is equal to [tex]324[/tex]° .

Step-by-step explanation:

Degrees are a unit of angle measure. A full circle is divided into 360 degrees. For example, a right angle is 90 degrees. A degree has the symbol ° and so ninety degrees would written 90°. Another unit of angle measure is the radian.

The radian is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics. The length of an arc of a unit circle is numerically equal to the measurement in radians of the angle that it subtends; one radian is just under 57.3 degrees.

We know that 1 radian = 180°/[tex]\pi[/tex] . So [tex]\frac{9\pi }{5}[/tex] radians is equal to :

⇒ [tex]\frac{9\pi }{5}(\frac{180}{\pi } )[/tex]

⇒ [tex]\frac{9(180) }{5}[/tex]

⇒ [tex]9(36)[/tex]

⇒ [tex]324[/tex]°

Therefore , [tex]\frac{9\pi }{5}[/tex] radians is equal to [tex]324[/tex]° .

To convert 9pi/5 radians to degrees, multiply by the conversion factor of 180°/π, resulting in 324 degrees.

To convert the angle 0 = 9pi/5 radians to degrees, we need to use the relationship between radians and degrees. Recall that 360° = 2π radians. Consequently, to convert radians to degrees, we can multiply by a conversion factor of 180°/π. Using this conversion factor, the computed angle in degrees is:

9π/5 radians × (180°/π) = 9/5 × 180° = 9 × 36° = 324°

Therefore, the angle of 9π/5 radians is equivalent to 324 degrees.

Answer:

Fourth answer choice.

Step-by-step explanation:

Start by factoring the numerator and the denominator:

(x - 1)(x + 1)

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

(x + 1)(x + 4)

Note that x can be neither -1 nor -4, since either results in an undefined quotient.  These two x-values are critical values because of this.  If we cancel the (x + 1) terms, we obtain the result

(x - 1)

--------- for x ≠ -1 and x ≠ - 4

(x + 4)

The next step is to evaluate the given quotient on the three intervals defined by {-4, -1}:  (-∞, -4), (-4, -1), (-1, ∞ ).  We choose an x-value from within each interval and evaluate the given function at each.  Suitable test values include {-10, -3, 0}:

At x = -10, the reduced given quotient (x - 1) / (x + 4) takes on the value  (-10 - 1) / (-10 + 4) = -11/(-6), which is positive.  Reject this interval, as we want and expect the quotient value to be 0 or less.

At x = -3, we get (-3 - 1) / (-3 + 4), which is negative.  The given inequality is true on the interval (-4, -1) (or -4 < x < -1).

At x = 0, we get (0 - 1) / (0 + 4), which is negative, so the inequality is true on (-1, ∞ ).

So the fourth answer choice is the correct one.

The length of EF in the given triangle is 8.80 m.

Step-by-step explanation:

Step 1:

In the given triangle, the opposite side's length is 16.2 m, the adjacent side's length is x m while the triangle's hypotenuse measures 16.2 m units.

The angle given is 90°, this makes the triangle a right-angled triangle.

So first we calculate the angle of E and use that to find x.

Step 2:

As we have the values of the length of the opposite side and the hypotenuse, we can calculate the sine of the angle to determine the value of the angle of E.

[tex]sinE = \frac{oppositeside}{hypotenuse} =\frac{13.6}{16.2} = 0.8395.[/tex]

[tex]E = sin^{-1} (0.8395), E = 57.087.[/tex]

So the angle E of the triangle DEF is 57.087°.

Step 3:

As we have the values of the angle and the hypotenuse, we can calculate the cos of the angle to determine x.

[tex]cos E = \frac{adjacentside}{hypotenuse} = \frac{x}{16.2} .[/tex]

[tex]cos(57.087) = 0.5433, x = 16.2 (0.5433) = 8.8014.[/tex]

Rounding this off to the nearest hundredth, we get x = 8.80 m.

Answer:

the answer is  about 4.243

Step-by-step explanation:

Squares mean all sides would have the same length. So you just need to find the square root of the area (18)  which is about 4.243 and just to check multiply 4.243 by itself and you would get 18.

Final answer:

The length of one side of the table top with an area of 18 square feet is approximately 4.24 feet, as calculated by taking the square root of the area.

Explanation:

To find the length of one side of a table top with an area of 18 square feet, we should understand that a square has all sides of equal length. Therefore, to find the side length of a square, we take the square root of the area. In this case, we have an area of 18 square feet, so the calculation would be √18, which is approximately 4.24 feet. Thus, the length of one side of the table top is approximately 4.24 feet.

Answer:

x = [tex]\frac{12}{17}[/tex] or 0.706

[tex]y = \frac{59}{34}[/tex] or 1.735

Step-by-step explanation:

5x + 2y=7    ----->(eq 1)

- 2x + 6y=9 ----->(eq 2)

Multiply (eq 1) with 3

3×(5x + 2y) = 3×7  

15x + 6y = 21  ----->(eq 3)

substract (eq 3) from (eq 2)

- 2x + 6y - (15x + 6y) = 9-21

- 2x + 6y - 15x - 6y = 9-21

- 2x - 15x + 6y - 6y = 9-21

-17x = -12

x = -12 ÷ -17

x = [tex]\frac{12}{17}[/tex]

put x = [tex]\frac{12}{17}[/tex] in (eq 1)

[tex]5*\frac{12}{17} + 2y = 7[/tex]

[tex]2y = 7- 5*\frac{12}{17}[/tex]

[tex]2y = \frac{7*17 - 60}{17}[/tex]

[tex]2y = \frac{119- 60}{17}[/tex]

[tex]2y = \frac{59}{17}[/tex]

[tex]y = \frac{59}{17*2}[/tex]
