Answer:
Total length of fabric pieces is 8400 mm.
Step-by-step explanation:
Eva buys a piece of red fabric of length = 5.6 meters
Since, 1 meter = 1000 mm
Therefor, 5.6 meter = 5.6 × 1000
= 5600 mm
Similarly, length of yellow fabric piece = 2.8 meters
≈ 2.8 × 1000 mm
≈ 2800 mm
If these pieces are joined together, total length of the fabric pieces
= 5600 + 2800
= 8400 mm
Therefore, total length of fabric pieces is 8400 mm.

Placed the following quadratic in vertex form by completing the square and then state the coordinates of its vertex?
Y=x^2+18x-12
Answer:
y = (x + 9)² -93
vertex: (-9, -93)
Step-by-step explanation:
x² + 18x = 12
x² + 18x + 81 = 12 + 81
(x+9)² = 93
y = (x + 9)² -93
vertex: (-9, -93)

in the equation y = mx + b, the m represents the slope and b represents the y-intercept
remember that slope is rise over run:
starting from the point (1, 1) you rise 2 up and go over left 1 to reach the second point shown (0, 3).
add a negative sign to show the negative downward slope, and the m in the equation would be -2
the y-intercept is just where the line hits the y-axis, or when the x in the ordered pair is 0. In this graph, one of the points given is (0, 3) so 3 is the y intercept
just plug all that into y = mx + b
m, the slope, is -2 and b, the y- intercept, is 3.
y = -2x + 3 is your answer
The eastbound train travels 10 miles per hour faster than the westbound train. After 2 hours, they are 232 miles apart. At what speeds are the two trains traveling?
Answer:
48,58
Step-by-step explanation:
Let The speed of the west bound train be x
Let the east bound train be x+10
The speeds can be calculated as follows
2(2x+10)= 232
4x + 40= 232
4x= 232-40
4x= 192
x= 192/4
= 48
Hence the speedof the west bound train is 48
The speed of the east bound train is 48+10
= 58

Which of the following transformations does not
preserve congruence?
F. (x,y) → (-x, -Y)
G. (x, y) = (-y, -x)
H. (x, y) = (x + 9.y + 9)
J. (x,y) → (9x, 9y)
Answer:
(9x, 9y) dilation
Step-by-step explanation:
(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.

Matrices is an array of numbers, symbols and expressions arranged in rows and columns. Matrices can be used to solve system of equations. Many mathematical operations can be done on matrices such as addition, subtraction, multiplication, scalar multiplication and so on.
Addition and subtraction of two matrices can be done if they have the same dimensions. This is done by simply adding or subtracting the corresponding entries in matrices.

state the angle pair relationship then find the value of x
Answer:
x = 11
Step-by-step explanation:
The given angles are corresponding angles and are congruent, then
12x - 9 = 10x + 13 ( subtract 10x from both sides )
2x - 9 = 13 ( add 9 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11
What is the solution to the system of equation of 2x+3y=6 and x-3y=9
Answer:
x = 5
y = -4/3
Step-by-step explanation:
Solve by elimination by adding the two equations together:
2x + 3y = 6
x - 3y = 9
3y and -3y will cancel out. Then, solve for x:
3x = 15
x = 5
Plug in 5 as x into one of the equations, then solve for x:
x - 3y = 9
5 - 3y = 9
-3y = 4
y = -4/3
So, the answer is x = 5 and y = -4/3
Ann runs a day care center. Of the last 18 children to enroll at the day care center, 8 of them have been elementary school students. Considering this data, how many of the next 9 children to enroll should you expect to be elementary school students?
We would expect that 4 of the next 9 children to enroll will be elementary school students.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If 8 out of the last 18 children to enroll at the daycare center were elementary school students,
We can find the fraction of elementary school students in that group by dividing the number of elementary school students by the total number of children:
= 8/18
= 4/9
This means that 4 out of every 9 children enrolled were elementary school students.
If we want to predict how many of the next 9 children to enroll will be elementary school students,
We can use this ratio:
4/9 of 9 children
= (4/9) x 9
= 4
Therefore,
We would expect that 4 of the next 9 children to enroll will be elementary school students.

A store offers a discount of 40%. The discount price of a shirt is $42 . What is the regular price?
Answer:
$70 is the regular price of the shirt.
Step-by-step explanation:
One way in which to find the regular price here is to write the equation
0.60s = $42. A 40% discount is reflected in 100% - 40%, or 1.00 - 0.40, which comes out to 0.60.
If 0.60s = $42, then the regular price of the shirt is
s = ($42)/0.60 = $70
Answer:
$70.00

If line segment AB,A(9,3) and B(-6,-9), what scale factor was used to dilate if new line is at A'(3,1) and B'(-2,-3)?
Answer:
The scale factor is 1/3
Step-by-step explanation:
Here, we want to get the scale factor used in dilating the original segment
As we can see;
(9,3) turned to (3,1)
looking at this , we can see that both coordinate values were divided by 3
So what this mean is that the particular scale factor used is reduction by 1/3
This is the case with the other point as (-6,-9) turned to (-2,-3)
