Answer:

Answer is c I think

Step-by-step explanation:

Answer:

Discount = Original Price x Discount %/100

Discount = 395.49 × 30/100

Discount = 395.49 x 0.3

You save = £118.65

Final Price = Original Price - Discount

Final Price = 395.49 - 118.647

Final Price = £276.84. (ANSWER)

original price of washing machine is $564.99 if the sale price of the washing machine is $395.49 with 30% off.

Percentage is defined as a given part or amount in every hundred

Based on the given conditions, formulate:

x×(1-30%)=395.49

Apply multiplicative distribution

x-0.3x=395.49

Combine the like terms

0.7x=395.49

x=395.49/0.7

Convert decimal to fractions

x=(39549/100)/(7/10)

x=39549/(10×7)

x=39549/70

x=564.99

Hence original price of washing machine is $564.99

You can use elimination and substitution method

EXAMPLE :

Given :

2x + y = 5

3x - 5y = 1

2x + y = 5 (× -5)

3x - 5y = 1

__________

-10x - 5y = - 25

3x - 5y = 1

____________ _ (elimination)

-13x = - 26

x = - 26/-13

x = 2

Substitution x = 2 to 2x + y = 5 :

2x + y = 5

2(2) + y = 5

4 + y = 5

y = 5 - 4

y = 1

Considering the zeros, the graph for the sinusoidal function is:

[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]

The sine function is given by:

[tex]F(x) = A\sin{Bx}[/tex]

In which:

In this problem:

[tex]\frac{2\pi}{B} = 14[/tex]

[tex]B = \frac{2\pi}{14}[/tex]

[tex]B = \frac{\pi}{7}[/tex]

Thus:

[tex]F(x) = \sin{\frac{\pi}{7}x}[/tex]

Like this, the zeros are at [tex]x = -14[/tex] and [tex]x = 0[/tex]. We want it at [tex]x = -11, x = 3[/tex], thus, we shift the function 3 units to the right, that is, the function is:

[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]

The graph is sketched at the end of this answer, and has the desired behavior, which are points (-11,0) and (3,0).

The equation of the parabola is gotten as;

 y = -4x² + 24x - 32

We are given the coordinates of a parabola to be;

(3, 4) ; (4,0) ; (2,0)

The general form of equation of a parabola is given by;

y = ax² + bx + c

Let's plug in the x and y coordinates as given to us from the question.

(3²)a + 3b + c = 4

9a + 3b + c = 4  ----(eq 1)

(4²)a + 4b + c = 0

16a + 4b + c = 0  ----(eq 2)

(2²)a + 2b + c = 0

4a + 2b + c = 0  ----(eq 3)

       y = -4x² + 24x - 32

Answer:

a. 1 1/2 (or 3/2)

b. 2/3

c. 1

d. 1

Step-by-step explanation:

Part A: (1,1) (7,5)

To determine the slope, you will use the equation m=(y2-y1)/(x2-x1). Keep in mind that it doesn't matter what point you use for (x1, y1) or (x2, y2).

Let's plug in the numbers for part a:

m=(7-1)/(5-1)

Let's then solve the problems inside the parentheses:

m=6/4

And finally, we simplify:

m=3/2 (or 1 1/2 depending on what your teacher wants for an answer)

For these others, I will just go through the steps and not explain them, if you need help or don't understand something I'm doing, either look back at what I did for part a or comment on this answer.

Part B: (1,1) (5,7)

m=(5-1)/(7-1)

m=(4/6)

m=2/3

Part C: (2,5) (-1,2)

m=(-1-2)/(2-5)

m=(-3/-3)

m=1

Part D: (2,5) (-7,-4)

m=(-7-2)/(-4-5)

m=(-9/-9)

m=1

percentage is similar to division.

Answer:

43xx

Step-by-step explanation:

5x(2x+7)+x(3x-5)

first, do the equations inside the parentheses

2x+7=9x

3x-5=-2x

so,

5x(9x)+x(-2x)

Next, do 5x times 9x

(5x) x (9x) = 45

so,

45+x(-2x)

Next, do x times (-2x)

(x) x (-2x)=-2xx

so,

45+-2xx

=43xx

1. At the end of the 5th week he would have saved a total of $700

2. The amount of flour he would have at the closing time on 17th of the month will be 16kg

1.

Azad amount = $500

He wants to go on a holiday but he lacks sufficient money. This means the $500 in his possession is not enough.

He decided to save $40 dollars per week for a number of weeks to make up the deposits.

let

w = number of weeks

Therefore, his saving for any number of weeks will be

The amount he would have saved for 5 weeks will be

40×5=$200

The total amount in his possession at the end of the fifth week will be  200 + 500 = $700

2.

The baker has 400 kg of flour. The first day of the month he didn't use any flour. This means on the first day of that month the flour was still 400 kg. The amount he has on the 17th day of the month can be calculated below.

The 17th day simply implies he used the flour for 16 days, the first day of the month he didn't use anything. He uses 24 kg for each day. Therefore the amount he uses for 16 days will be

The amount he has at the closing time of 17 days of the month will be

hello thank you for brainliest

The result if the inequality expressions are v ≥ 10 and v < 0

Given the following inequality expression

7v- 5 ≥ 65 or -3v - 2 ≥ -2

Solve the inequality individually

7v - 5 ≥ 65

Add 5 to both sides

7v - 5 + 5 ≥ 65 +5

7v ≥ 70

v ≥ 70/7

v ≥ 10

For the inequality-3v - 2 ≥ -2

Add 2 to both sides

-3v - 2 + 2≥ -2 + 2

-3v ≥ 0

v < 0

Hence the result if the inequality expressions are v ≥ 10 and v < 0

Answer:

The bottom point is at (-1, 1) the right point is at (6,-2) and the left point is at (-5,4)

Step-by-step explanation:

Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4).

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

If a coordinate of any polygon (x,y) is rotated 180 degrees about the origin either clockwise or anticlockwise then its coordinate will change sign.

(x,y) → (-x,-y)

Given triangle have coordinates as (-1,1),(-2,6), and (-5,4).

The transformation (x,y) → (-x,-y) gives ;

(-1,1) → (1,-1)

(-2,6) → (2,-6)

(-5,4) → (5,-4)

Hence "Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4)".
