A 56-inch board is to be cut into three pieces so that the second piece is 3 times as long as the first piece and the third piece is 4 times as long as the first piece. The length of all the three pieces are : 7, 21, 18.

There are 3 pieces:

Length of first piece = x

Length of second piece = 3x

Length of third piece = 4x

Total length = 8x

Now, 8x = 56

Divide both side by 8x

x = 56 /8

x = 7

Length of second piece = 3x where x = 7

3x = 3 ( 7)

=  21

Length of third piece = 4x where x = 7'

4x = 4 ( 7)

=  28

Therefore we can conclude that the length are : 7, 21, 18.

So definetly Jayden's solution is not correct.

Let's check the second statement: that's what we just did - add the parentheses before dividing. If Jayden would've done that he would have arrieved at the same solution we did, so definetly this statement is false

The third statement could be true. Let's see which value of a gives 8.5 as a result:

If 'a' were 29.75, Jayden would be correct.

Let's see what happens if we divide 14 by 2 and then add 1.5:

This is the result Jayden got, so definetly this is one option for what he did wrong.

Answer:

When two planes  which are 2505 miles apart and fly toward each other. if their speeds differ by 85mph and If they pass each other in 3 hours, then the speed of first plane is 372.5 mph and the speed of second plane is 462.5 mph

Their speeds differ by 85mph

Consider the speed of first plane = x mph

The speed of second plane = 90+x mph

The relative speed = sum of both speed

= x + x+90

= 2x+90 mph

The distance between the planes = 2505 miles

Time taken to pass each other = 3 hours

Therefore in 3 hours

3(2x+90) = 2505

6x+270 = 2505

6x = 2505-270

6x = 2235

x = 2235/6

x = 372.5 mph

The speed of second plane = 90+x

= 90+372.5

= 462.5 mph

Hence, when two planes  which are 2505 miles apart and fly toward each other. if their speeds differ by 85mph and If they pass each other in 3 hours, then the speed of first plane is 372.5 mph and the speed of second plane is 462.5 mph.

The greatest common factor is the greatest number that divides both numbers.

The given numbers are 574 and 532.

First, let's decompose each number into their prime factors.

574 | 2

287 | 7

41 | 41

574 = 2*7*41

532 | 2

266 | 2

532 = 2*2*7*19

As you can observe, the common factors are 2 and 7, so the greatest common factor is 14 since that's the product between 2 and 7.

In order to find any pair of points that have a midpoint of (4, -10), we can choose any two values p and q. Then, one of the endpoints will be (4+p, -10+q) and the other endpoint will be (4-p, -10-q).

For example, let's choose p = q = 2, so we have:

Therefore the ordered pairs (6, -8) and (2, -12) have a midpoint of (4, -10).

In order to graph the functiom we need to identify the parent function and the vertical and horizontal shifts that might be done to the function.

In this case we see that the parent function is a cubic function since the greater degree is 3

this means that f(x) is a transformation of g(x)

then

the horizontal shifts since there is sum inside the parentheses the shift will be 1 unit to the left.

the vertical shift will be 1 unit up since there is a sum outside the parentheses.

and finally since there is a - it means that the function is reflected over the x-axis

the parent function will be the red line and the function #15 is the blue line.

In order to find points we can tabulate the values for given xs' and construct the graph.

Start by making a table like this:

now since the function is given we can replace x with the values and find y

then after tabulating values should look like this

Now looking at the graph on the blue function we can see that the function is decreasing until reaching x=-1, however after that the function will continue to decrease but at a different rate, which means that over the interval

the function will be decreasing

The three transformations—rotations, reflections, and translations—can be combined to produce congruent shapes. The truth is that any pair of congruent shapes can be matched to one another by combining one or more of these three transformations.

Explain transformations.

A point, line, or geometric figure has four different transformations that can be applied to alter its appearance. While the term "Image" refers to the position and final shape of the object, "Pre-Image" refers to the object's shape before transformation.

Given Information

The size and shape of the figures are preserved during stiff transformations, as we already know (reflections, translations, and rotations). Always in harmony with one another is the pre-image.

These transformational skills are all possessed by Matt:

Reflection

The reason a reflection maintains its original form Comparable locations between the pre-image and the picture remain apart from the line of reflection.

Rotations as a Transformation of Congruence

When a figure rotates, it twists. Despite being the same size and shape, the figurine appears to have toppled over. A clock is an excellent example of how the globe rotates in reality. Every hour or every day, the connecting arms of a clock revolve around its axis. The degree of a rotation determines what kind of rotation it is; popular rotations include 90, 180, and 270 degrees. Before spinning around completely and going back to where it started, the figure rotates 360 degrees. the clockwise or counterclockwise direction in which a rotation is made. This data can be used to determine the degree, amount, a revolution's speed and direction.

Congruence translational transformation

When an object or shape is transferred from one location to another without altering its size, shape, or orientation, we refer to the transfer as a movement. A translation, often known as a slide, involves moving every point on an object or shape uniformly and in one direction.

Ally has a square backyard with an area of 169 square feet.

Given a square of side length, s

Therefore:

Therefore, the length of one side of the backyard is 13 feet.

Answer:

3, 8

Step-by-step explanation:

Let's make the first integer x and the second integer y.

Now, you take the information given and convert it into a system of equations:

xy = 24

x = 5y - 7

y = 24 / x

Now, we substitute:

(5y - 7) · y = 24

Distribute y

5y² - 7y = 24

Rearrange it into a quadratic equation:

ax² + bx + c = 0

5y² - y - 24 = 0

Use the quadratic formula (shown in image) and plug in the values:

x = (- (7) ± [tex]\sqrt{(-7^})^{2} -4(5)(-24)}[/tex] ) / 2(5)

[tex]\sqrt{(-7)^{2} -4(5)(-24)}[/tex] = [tex]\sqrt{49 - (-480)} = \sqrt{529} = 23[/tex]

Remember that ± means there are two y values

[tex]x = \frac{7+23}{10} = \frac{30}{10} = 3[/tex]

and

[tex]x = \frac{7-23}{10} = \frac{-16}{10} = -1.6[/tex]

Since y must be an integer, we know that y = 3

Now, plug in y:

5(3) - y = 24

15 - y = 24

- y = -24

y = 8

Let's check to see if we are right:

5y - 7 = 5(3) - 7 = 15 - 7 = 8

It works!

Let:

y=2x+18 (1)

4x+5y=20 (2)

replace (1) into (2)

4x+5(2x+18)=20

Using distributive property:

4x+10x+90=20

Add like terms:

(4x+10x)+90=20

14x+90=20

subtract 90 from both sides:

14x+90-90=20-90

14x=-70

Divide both sides by 14:

14x/14=-70/14

x=-5

Finally, replace the value of x into (1)

y=2(-5)+18

y=-10+18

y=8

Let:

2x+2y=6 (1)

3x-5y=25 (2)

From (1) let's solve for x:

subtract 2y from both sides:

2x+2y-2y=6-2y

2x=6-2y

Divide both sides by 2:

x=(6-2y)/2

x=3-y (3)

Replace (3) into (2)

3(3-y)-5y=25

Using distributive property:

9-3y-5y=25

Add like terms:

9+(-3y-5y)=25

9-8y=25

subtract 9 from both sides:

9-8y-9=25-9

-8y=16

Divide both sides by -8:

(-8y)/(-8)=(16)/(-8)

y=-2

Finally, replace the value of y into (3)

x=3-(-2)

x=3+2

x=5

ANSWER:

The quadratic function in standard form is g(x)= x²-10x+0

Quadratic functions are polynomial functions of the second degree, meaning they contain at least one squared term.

Quadratic functions are another name called quadratics. The quadratic function has the following general form: f(x)=ax² + bx + c.

An quadratic function is given as g(x)= x²-10x

In the standard form of the quadratic equation, there should be three terms, terms with power two, one and a constant.

In the given equation, there is a constant term missing.

So, we add a zero to the end because it brings no change to the function quantitatively.

So, the standard form of the given quadratic function will be g(x)= x²-10x+0
