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.
LengthThere 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

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
[tex]g(x)=x^3[/tex]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
[tex]\begin{gathered} y=-(x+1)^3+1 \\ y=-(-6+1)^3+1 \\ y=-(-5)^3+1 \\ y=-(-125)+1 \\ y=125+1 \\ y=126 \end{gathered}[/tex]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
[tex](-\infty,\infty)[/tex]the function will be decreasing

use the method of dividing by prime factors to find the greatest common factor of the following numbers 574 and 532
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
1
574 = 2*7*41
532 | 2
266 | 2
133 | 7
19 | 19

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.
Therefore, the greatest common factor between 574 and 532 is 14.What are two ordered pairs that the midpoints (4, -10)? Please show that your points work.

Solve the system by using the substitution method.y = 2x + 184x + 5y = 20
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)

Two planes, which are 2505 2505 miles apart, fly toward each other. Their speeds differ by 85mph 85 mph . If they pass each other in 3 3 hours, what is the speed of each?
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.

one integer is 7 less than 5 times another. Their product is 24. Find the integers.
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

Answer:
5 cups of flour.
Step-by-step explanation:
I know the wording of the problem may be confusing at first, but if you look at it a little bit, it's just multiplication and division.
To start,
12 biscuits require 2 cups of flour,
meaning that 6 biscuits (half of the original) only require 1 cup.
(12/2 = 6)
Next,
We need to find how much flour is in 30 biscuits.
We know that 1 cup is in 6 biscuits, and if you were to find how much was in 30 biscuits, you would just need to divide 30 by 6.
(30/6 = 5)
5 cups of flour would be your answer.
To put it mathematically,
(12/2 = 6), (30/6 = 5)

Describe a series of transformations Matt can perform to decide if the two windows are congruent
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.
