What is the correct expanded from and value of 4^3

Answer:

(- 5, 4 )

Step-by-step explanation:

under a reflection in the line y = x

a point (x, y ) → (y, x ) , then

G (4, - 5 ) → G' (- 5, 4 )

The coordinates of the image of vertex G are (-5, 4)

When reflecting a figure in a line or in a point, the image is congruent to the pre image. A reflection maps every point of a figure to an image across a fixed line. The fixed line is called the line of reflection.

here, we have,

Let us revise some cases of reflection

If the point (x, y) reflected across the x-axis , then its image is (x, -y)

If the point (x, y) reflected across the y-axis , then its image is (-x, y)

If the point (x, y) reflected across the line y = x , then its image is (y, x)

If the point (x, y) reflected across the line y = -x , then its image is (-y, -x)

From the given figure

∵ The line of the reflection is y = x

→ That means we will switch the coordinates of the point to find its image

∵ The coordinates of vertex G are (4, -5)

∴ The x-coordinate = 4 and the y-coordinate = -5

→ Switch the two coordinates

∴ The coordinates of its image G' are (-5, 4)

∴ The coordinates of the image of vertex G are (-5, 4)

Step-by-step explanation:

the perimeter is

2×length + 2×width = 86

length = 3×width

now we use the second equation as variable identity in the first equation :

2×3×width + 2×width = 86

6×width + 2×width = 86

8×width = 86

width = 86/8 = 43/4 = 10.75 cm

length = 3×width = 3×10.75 = 32.25 cm

Using proportions, it is found that it's value before the 2-day drop was of 264 points.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the value dropped by 25%, that is, it was 75% of the original amount, and the dropped value was of 198 points, hence the original amount was:

0.75x = 198

x = 198/0.75

x = 264

By reading the box plot :

The median is the number that corresponds to the line in the center of the box which is 15 in our case.

Kellie's original number given the analogy and corresponding equation is 13

let

(x × 2) × 3 = x + 65

2x × 3 = 65 + x

6x = 65 + x

6x - x = 65

5x = 65

x = 65/5

x = 13

check:

6x = 65 + x

6(13) = 65 + 13

78 = 78

Therefore, the unknown number, x is 13

Answer:

No solution

Step-by-step explanation:

[tex]3(5x - 4) < 15x \\ 15x - 12 < 15x \\ 15x - 15x < 12 \\ 0 < 12[/tex]

19x+12y=17

step 1: move the thing that you're looking for to the left side and all the rest to the right side:

(19x +12y)-19x = 17 -19x

12y = 17 -19x

step 2: to find y, you need to get rid of 12. to do so you need to devide everything by that number:

(12y)/12 = 17/12 -19/12 x

y= 17/12 -19/12 x

step 3: simplify of possible. ( in this exercise it isnt)

step 4: rearange the equation if necessary

y= 17/12 + -19/12x

y= -19/12x + 17/12

Answer:

  $3.65

Step-by-step explanation:

The two purchases describe relations between quantity and price that can be used to write a system of equations for the prices of the hockey pucks and hockey sticks. These equations can be solved to find the price of a hockey puck.

__

Let x and y represent the prices of a hockey puck and a hockey stick, respectively. The two purchase values are ...

  5x +3y = 23.50

  5x +y = 20.00

Rearranging the second equation, we have an expression for y:

  y = 20.00 -5x . . . . . . subtract 5x from both sides

Substituting this into the first equation gives ...

  5x +3(20.00 -5x) = 23.50 . . . . . substitute for y

  -10x +60.00 = 23.50 . . . . . . simplify

  x -6.00 = -2.35 . . . . . . . . divide by -10

  x = 3.65 . . . . . . . . . . . add 6

One hockey puck costs $3.65.

The answer is A , for determining range look at Y-axis only from down to up .For this question we can also say

range: [1,7] , if both ends of the line are arrows it means the line goes from negative infinity to positive infinity (which means range is all real numbers) , but if the point is include just like this graph the points will be also include in range , but if the points are an empty circle the points won't be include for writing range

Explanation

On a 6 sided die, there are three even numbers (2,4,6)

That's 1/2 the number on the die.

So getting 6 even numbers is

P(6) = 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 0.00781

Where did that extra 1/2 come from? Well one of the numbers thrown was an odd number, and it has to be counted.

P(7) = the same answer.                            0.00781

Total                                                           0.0156

Vowels = {a, e, i, o, u}

There are 5 vowels out of 26 letters in the English alphabet. This leaves 26-5 = 21 consonants.

The theoretical probability of getting a consonant is 21/26 = 0.8077 = 80.77% approximately

Wayne found the empirical probability of a consonant as 60% which is quite a distance away from the 80.77% mentioned. The discrepancy is likely because vowels are tended to be used quite often in many words.

Words that are composed of consonants only are quite rare, but they do happen. Example: "fly" is a word with only consonants. I'm considering y to be a consonant.

The values that represent those having type O blood are the values from 000 to 449.

RNG refers to a random number generator, this means that from 000 to 999 (a total of 1000 numbers) each has the same probability of being randomly selected by the program.

Then, if we want to represent a probability of the 45%, then 0.45 of the number of elements must be assigned to what we want to represent (having type O blood).

0.45*1000 = 450

Then we can assign the first 450 numbers to have type O blood, the first 450 numbers are: {000, 001, ..., 449}

So the values that represent those having type O blood are the values from 000 to 449.

The vertex form of all expressions is given below.

We have given that the expressions

We have to write the function in vertex form.

The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Therefore the first equation

[tex]f(x)=(x-1)^2-7[/tex]

it can be written as

[tex]f(x)=1(x-1)^2+(-7)[/tex]

The second equation can be written as

[tex]f(x) = (x+1)^2 -7[/tex]

vertex for is,

[tex]f(x)=1(x-(-1))^2+(-7)[/tex]

The third equation is,

[tex]f(x) = (x -1)^2 - 5[/tex]

Vertex form is,

[tex]f(x)=1(x-1)^2+(-5)[/tex]

Forth equation is,

[tex]f(x) = (x +1)^2 +(- 5)[/tex]
