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

Answer:

Value of f(-10) is 1100

Step-by-step explanation:

Given that f(x) = x² - x³

Here we need to find f(-10).

 f(-10) =  (-10)² - (-10)³

 f(-10) = 100 - (-1000)

 f(-10) = 100 + 1000

 f(-10) = 1100

Value of f(-10) is 1100

Answer:

False

Step-by-step explanation:

1+1=2 is clearly true.

2+3=4 is clearly false.

x if and only if y has a value of true if x and y are both true or both false. It is false otherwise.

So, true if and only if false has a value of false, so the answer is [tex]\boxed{false}[/tex]

Answer:

y=-3x+1

Step-by-step explanation:

1) the slope-interception form is: y=slope*x+intercept;

2) if A(0;1) and B(2;-5) then it is possible to make up the equation of the required line:

[tex]\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A}; \ => \ \frac{x}{2}=\frac{y-1}{-6};[/tex]

3) the equation in the item 2 can be written in slope-interception form:

x=(y-1)/(-3); ⇔ y-1= -3x; ⇔ y= -3x+1.

P.S. note, the suggested way of solution is not the shortest one.

Answer:

Step-by-step explanation:

A function is one-to-one if it passes the horizontal line test.  This is the case if a horizontal line intersects the graph in only one place.  

The graph of f(x) = x^2 - 5 is that of a parabola that opens upward.  There are several possibilities here:

1.  The horizontal line intersects the parabolic graph twice on the interval (-infinity,+infinity).  Therefore this function is not one-to-one on this interval

(-infinity,+infinity).

2. If we define the domain as [0,+infinity), a horizontal line will intersect this parabolic graph only once.  Therefore this function is one-to-one on [0,+infinity).

Step-by-step explanation:

Answer:

104

Step-by-step explanation:

∠JTS = ∠SRT  + ∠TSR   {exterior angles equals sum of opposite interiror angles}

27x - 4 = 18x + 2 + 30

27x  - 4 = 18x + 32

Add 4 to both sides

27x = 18x + 32 + 4

27x = 18x + 36

Subtract  18x from both sides

27x - 18x = 36

9x = 36

Divide  both sides by 9

x = 36/9

x = 4

∠JTS = 27x - 4

         = 27*4 - 4

         = 108 - 4

        = 104

Answer:

You probably already figured it out, but the correct answer is the last one. Subtract 3 from the product of 9 and m

Step-by-step explanation:

Reason for this is 9m is the same as 9 multiplied by m, or the product of 9 and m. You always do multiplication before subtracting or adding, therefore you are subtracting 3 FROM the product of 9 and m

Answer: 65

Step-by-step explanation:

all angles of a triangle will add up to be 180 degrees there for add 80 + 35 to get 115 degrees and then subtract 115 from 180(180-115) to get the third angle of 65 degrees

Answer:

65

Step-by-step explanation:

80+35+?=180

115+?=180

Equality Properties

Rewriting Fractions

Step-by-step explanation:

Step 1: Define

1 2/3 ≥ r - 7/12

Step 2: Solve for r

Rewrite:                    5/3 ≥ r - 7/12

Isolate r:                    9/4 ≥ r

Rewrite:                    r ≤ 9/4

Reduce:                    r ≤ 2 1/4

Here we see that any number r less than or equal to 2 1/4 will work as a solution to the inequality.

[tex] - 23x(x + 3) \\ { - 23x}^{2} - 69x \\ \\ \\ \\ \\ \\ hope \: it \: helps \\ stay \: safe \: healthy \: nd \:and \: happy[/tex]

Answer:

[tex]-23x^{2} -69x[/tex]

Step-by-step explanation:

Using the distributive property:

[tex]-23x(x+3)[/tex]

You will multiply both the x and the 3 inside the parantheses by the -23x outside.

[tex]-23x[/tex] · [tex]x = -23x^{2}[/tex]

Then:

[tex]-23x[/tex] · [tex]3 = -69x[/tex]

If you combine both you will recieve:
