What is the percent of change from 8 to 4?

Answer:

(-4, 2)

Step-by-step explanation:

4x+2y=-12

3x+y=-10

Start by dividing the first equation by 2 to simplify it...

2x+y=-6

Then, subtract -2x from both sides to isolate y...

y=-2x-6

Substitute -2x-6 for y in the second equation...

3x-2x-6=-10

Combine like terms...

x-6=-10

Add 6 to both sides

x-6+6=-10+6

x=-4

Plug -4 in for x to solve for y:

3(-4)+y=-10

-12+y=-10

Add 12 to both sides

-12+12+y=-10+12

y=2

(x,y)=(-4,2)

Answer:

y < 8 and D is my answer

Step-by-step explanation:

-8y > -64

-8. -8

when we reach at this stage, like terms cancel each other to make y subject of the formula

thus

And because y is becoming a postive value, the sign wI'll change to <

y < 8

Value of [tex]x[/tex]is [tex] - 12[/tex].

Final Answer is [tex]480[/tex]

Step-by-step explanation:

Assume that:

First number = x

Second number = 20 - x

Putting the given conditions,

[tex]2x^{2} + 3(20 - x)^{2} [/tex]

Putting the formula (a-b)²=(a²+2ab+b²) in (20-x)²,

[tex]2 {x}^{2} + 3(20^{2} - 2 \times 20 \times x + {x}^{2})[/tex]

[tex] = > 2 {x}^{2} + 3(400 - 40x + x^{2})[/tex]

Opening the brackets,

[tex]2 {x}^{2} + 3 \times 400 - 3 \times 40x + 3 \times {x}^{2} [/tex]

[tex] = > 2 {x}^{2} - 1200 - 120x + 3{x}^{2}[/tex]

[tex] = > (2x^{2} + 3 {x}^{2}) - 120x + 1200[/tex]

[tex] = > 5 {x}^{2} - 120x + 1200[/tex]

[tex]As \: x= - \frac{b}{2a}[/tex]

[tex] = > - \frac{120}{2 \times 5}[/tex]

[tex] = > - \frac{120}{10} [/tex]

[tex] = > - 12[/tex]

Now substituting the value of x in 5x²-120x+1200,

[tex] = > (5 \times {12}^{2} )-(120 \times 12)+1200[/tex]

[tex] = > (5 \times 144)-(1440)+1200[/tex]

[tex] = > 720 - 1440 + 1200[/tex]

[tex] = > 720 - (1440 - 1200)[/tex]

[tex] = > 720 - 240[/tex]

[tex] = > 480[/tex]

Answer:

5 cm

Step-by-step explanation:

Square has the formula = S × S

S × S = S²

S = Side

Square has an area 25 cm²

Length of a side of the square :

25 cm² = S²

S² = 25

S = √25

S = 5 cm

Given:

[tex]\frac{8}{24}=\frac{2}{63}[/tex]

Solution:

We can cross multiply to see if this proportion works.

[tex]63\times8=504[/tex]

[tex]24\times2=48[/tex]

[tex]48\neq 504[/tex]

As we can see, 48 and 504 does not equal.

   2d = r

   d = 5

   Canute (c) is 18

Answer: 1/2

Step-by-step explanation:

Step-by-step explanation:

In the diagram, AB is adjacent to Angle"a", because if we don't consider hypotenuse, it is the only associated segment to the angle.

The segment opposite to the right angle is called Hypotenuse.

The last one, AC segment, is called the Opposite because it is the opposite to Angle"a".

If we look at it from AngleC, however, its Adjcent will be segment AC, and Opposite will be segment AB.

Answer:

Step-by-step explanation:

The cost per kilogram is found by dividing cost by kilograms:

honeydew:

  ($4)/(2 kg) = $2/kg

Honeydew costs $2 per kilogram.

__

watermelon:

Let w represent the cost per kg of watermelon. The total value of the second purchase was ...

  (1 kg honeydew)×($2/kg) +(2 kg watermelon)×(w) = $3

  $2 +2w = $3

  2w = $1 . . . . . . . . . . . . subtract $2

  w = $1/2 = $0.50 . . . . divide by 2

The watermelon cost $0.50 per kilogram.

Answer:

1. False

2. False

Step-by-step explanation:

The statement "BC and B'C' are on the same line" is false, and the statement "the lengths of CD and C'D' are equal" is false.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

Quadrilateral A'B'C'D prime is the result of dilating quadrilateral ABCD about point P by a scale factor of 5/3

To determine whether each claim about the properties of ABCD and A'B'C'D' is true or false.

The points in the image by multiplying the coordinates of the points in the preimage by the scale factor.

Thus, the statement "BC and B'C' are on the same line" is false and the statement "the lengths of CD and C'D' are equal" is false.

Answer: 6+2x

Step-by-step explanation:

6 is the fixed cost so you add six regardless of how many kilos you travel. You add the 2x because they charge 2 dollars for every extra kilometer. The x is kilometers(which you don’t know how many you travel.) so you add 6+2x to get the cost.

Linear equation is equation in which each term has at max one degree. The formula for the cost of the journey is y = $6 + $2(x).

Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form,

y = mx + c

Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.

The given condition can be modelled using a linear relationship.

It is given that there is a fixed charge of $6 and an additional charge of $2 per kilometre. Therefore, the total charge,y can be modeled as,

y = $6 + $2(x)

where x represents the number of kilometres

The formula for the cost of the journey in Words​ is 6 plus two times of x, where x represents the number of kilometres.

Hence, the formula for the cost of the journey is y = $6 + $2(x).

Answer:

$221

Step-by-step explanation:

The original percent is always 100%. Add the markup, 70% to 100% to find the total percent charged.

100% + 70% = 170%

Change 170% to a decimal by moving the decimal two places left. 170% = 1.70

Multiply the decimal and the wholesale price.

$130 x 1.70 = $221
