Answer:

the answer for this problem is (x,y)=(0,9)

Answer:

y = 9

x = 0

Step-by-step explanation:

5x + 2y = 18

-5x + 5y = 45 add two equations up

5x + 2y -5x + 5y = 18 + 45 add like terms (note that, 5x will eliminate -5x)

7y = 63 divide both sides by 7

y = 9 to find the value of x we can use this information

5x + 2y = 18 replace y with 9

5x + 2*9 = 18

5x + 18 = 18 subtract 18 from both sides

5x = 0 and x = 0

       ➠ $15017.64

   c) r (any rate)

       ➠ $16,368 − r%

How did I find my answers?

I had to find the sales tax, and subtract it from the overall cost of the item.

Answer: 50%

Step-by-step explanation:

Number of women magazines = 37

Number of other magazines = 37

Total number of magazines = 37 + 37 = 74

The percentage of the magazines at the bookstore that are women's magazines will be:

= Number of women magazines / Total number of magazines × 100

= 37/74 × 100

= 1/2 × 100

= 50%

Answer:

D) 3/2

Step-by-step explanation:

(0 , 0 ) and (2,3)

Slope:

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

m=(3-0)/(2-0)

m= 3/2

Answer:

Explanation:

Slope = y/x

once the variable x > 0 the table satisfies 3/2

Step-by-step explanation:

A invested 450

B invested 150

C invested 600

total investment was 1200

share of A is 450/1200 = .375

share of B is 150/1200 = .125

share of C is 600/1200 = .5

C received a profit of 24.70.

that would be .5 of the total profit.

if we let x = total profit, we get .5 * x = 24.70

solve for x to get x = 24.70 / .5 = 49.40

A share of total profit = .375 * 49.4 = 18.525

B share of total profit = .125 * 49.4 = 6.175

C share of total profit .5 * 49.4 = 24.7

total profit = 49.4 as we had calculated earlier.

Answer:

Answer:

x= 7

x=-1

Step-by-step explanation:

- Multiply the coefficient of the first term by the constant   1  -7 = -7

- Find two factors of  -7  whose sum equals the coefficient of the middle term, which is   -6 .

-7+ 1 = -6

-Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -7  and  1.

x^2-7x+1x-7

- Add up the first 2 terms, pulling out like factors.

x • (x-7)

Answer:

A trust can protect your assets for the next generation. However, if you have debt, the trust will not necessarily protect assets from creditors. If you or your beneficiaries file for bankruptcy, for example, the trust could be seized for repayment of debts.

Given:

A semicircle with radius 7 cm.

To find:

The circumference of the given semi circle.

Solution:

We know that,

Circumference of a semi circle = Half of circumference of the circle + Diameter

                                                    [tex]=\dfrac{1}{2}(2\pi r+d[/tex]

                                                    [tex]=\pi r+2r[/tex]

Putting [tex]\pi=\dfrac{22}{7},r=7[/tex], we get

Circumference of the semi circle [tex]=\dfrac{22}{7}(7)+2(7)[/tex]

                                                        [tex]=22+14[/tex]

                                                        [tex]=36[/tex]

Therefore, the circumference of the given semi circle 36 cm.

America, the West Indies, or another part of the Americas that had direct contact with

Europeans. Tell the story in chronological order, but feel free to skip whole years or

Answer:

The relationship between these two sequences is it always doubles.  When we look at each sequence, 1, 2, 3, 4, 5, each number is multiplied by 2 to create the other sequence.

1 x 2 = 2.

2 x 2 = 4.

3 x 2 = 6.

4 x 2 = 8.

5 x 2 = 10.

When we arrange these numbers, 2, 4, 6, 8, 10, this is the exact sequence as before.  Therefore, this is the relationship.

Answer: 2, 4, 6, 8, 10,                           <                                |

Answer:

El valor total de la cuenta después de 5 años es de $3,598.

Step-by-step explanation:

Para encontrar la respuesta, tienes que utilizar la fórmula para encontrar el valor futuro:

VF=VP*(1+i)^n

VF=valor futuro

VP= valor presente=$3000

i=tasa de interés=0.037

n=número de periodos de tiempo=5 años

Ahora, puedes reemplazar los valores en la fórmula:

VF=3,000*(1+0.037)^5

VF=3,000*(1.037)^5

VF=3,598

De acuerdo a esto, la respuesta es que el valor total de la cuenta después de 5 años es de $3,598.

Answer:

. Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2) Step-by-step explanation:

Answer:

D) 65

Step-by-step explanation:

<1 = 11x + 5

<2 = 8x - 15

These angles are supplementary so,

11x + 5 + 8x - 15 = 180

19x - 10 = 180

19x = 190

x = 10

m<2:

8x - 15

8(10) - 15

Answer:

y=c+6

Step-by-step explanation:

this is the only equation I could think that fits the situation

hope this helped!

Step-by-step explanation:

Since ABC is a triangle,

Angle A + Angle B + Angle C = 180 (Sum of angles in a triangle)

given Angle A = 3x + 1

Angle B = 4x - 17

Angle C = 5x - 20

[tex]3x + 1 + (4x - 17) + (5x - 20) = 180 \\ 3x + 4x + 5x + 1 - 17 - 20 = 180 \\ 12x - 36 = 180 \\ 12x = 180 + 36 \\ 12x = 216 \\ x = 216 \div 12 \\ = 18[/tex]

Now substitute x into all 3 angles.

A = 3(18) + 1 = 54 + 1 = 55 degrees

B = 4(18) - 17 = 72 - 17 = 55 degrees

C = 5(18) - 20 = 90 - 20 = 70 degrees

Since Angle A = Angle B but not equal to Angle C,

Triangle ABC is a isosceles triangle as 2 angles must be the same for it to be a isosceles triangle.

Answer:

The quadrant that point A lies on is the second quadrant.

Step-by-step explanation:

The quadrants of a coordinate plane are quadrant I, II, III, and IV; the direction is counterclockwise with the first quadrant being the top right, making the top left quadrant II, bottom left quadrant III, and bottom right quadrant IV. Point A is located in the second quadrant, so that is the correct answer.

Answer:

y = 10 - 0.3t

Step-by-step explanation:

Amount of cat food purchased= 10 pounds

Daily pounds fed to dog = 0.3 pounds

How the amount of cat food in bag changes over time ;

Let y = amount of cat food left in bag

t = number of days since cat food was purchased

Amount of cat food left in bag = amount of cat food purchased - (daily pounds fed to dog * Number of days since cat food was purchased)

y = 10 - 0.3t

Answer:

50.1ft approx

Step-by-step explanation:

Given data

Height=14ft

Slant height= 52ft

Applying Pythagoras theorem, we can solve for the horizontal lenght

we know that

hyp^2= Opp^2+Adj^2---------- Pythagoras theorem

52^2=14^2+x^2

2704=196+x^2

2704-196=x^2

2508=x^2

x= √2508

x=50.07

Hence the horizontal distance is 50.1ft approx
