Answers
The coordinates of the vertices of the pre-image are A (3, -6), B(1, 2), C (7, -1).
According to the statement
We have to find that the coordinates of the points in the pre-image..
So, For this purpose, we know that the
Coordinates are a set of values which helps to show the exact position of a point in the coordinate plane.
From the given information:
After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are A'(6, 3), B'(-2, 1),and C(1, 7).
Then
We need to search out the coordinates of the pre-image A, B and C.
The rule for rotation of 90° about the origin is (x,y) ---> (-y,x).
But we want to seek out the coordinates of the vertices of the pre-image.
So, we'd like to use rule (-y,x) ---->(x,y).
Applying rule,
A'(6, 3) -----> A (3, -6)
B'(–2, 1) -----> B(1, 2)
C'(1,7) -----> C (7, -1).
Therefore, The coordinates of the vertices of the pre-image are A (3, -6), B(1, 2), C (7, -1).

Which expression is equivalent to (2x − 1)(4x + 3) − (9x + 1)(2x − 1)?
Answers
The given expression (2x − 1)(4x + 3) − (9x + 1)(2x − 1) is equivalent to -10x^2 + 9x - 2, that is, option b.
If terms of the form (a + b) and (a + c) are to be multiplied, then each number or variable in the 1st term is multiplied by every variable in the 2nd term. Thus, (a + b)(a + c) = a^2 + ac + ab + bc.
Here, we are given an expression (2x − 1)(4x + 3) − (9x + 1)(2x − 1)
let us simplify the given expression-
[2x(4x) + 3(2x) -4x - 3] - [9x(2x) -9x + 2x -1)]
8x^2 + 6x - 4x - 3 - (18x^2 -9x + 2x -1)
8x^2 + 2x - 3 - 18x^2 +7x +1
8x^2 -18x^2 + 2x +7x -3 +1
-10x^2 + 9x - 2

2. The rectangle must have 4 rows.
3. The rectangle must have the least possible number of columns.
Answers
The least possible number of columns is 7
2 blank tiles is will be used
Yes using multiplication facts the question can be solved.
Given data
Alphabet arrangement on tiles
The rules for arrangement of the alphabets
1. They must form a rectangle.
2. The rectangle must have 4 rows.
3. The rectangle must have the least possible number of columns.
How to find the column of tiles the arrangement will havenumber of alphabets = 26
let the row represent the width of the rectangle, so that the rectangle has 4 rows.
The length will be
length * width = 26
length = 26 / width
length = 26 / 4
length = 6.5 ≅ 7
Hence the least possible number of columns is 7
How to find the number of blank tiles used
26 / 4 gives 6 remainder 2 hence it requires 2 more tiles to make it up a rectangle of 7 columns.
The remaining part is filled with blank tiles therefore 2 blank tiles is used
How to solve the problem with multiplication factUsing multiplication we solve the problem as thus:
let the number of column be x such that
4 * x = 26
x = 26 / 4
so we use blank tiles to make the equation divisible by 4 without remainder.
using mental math: 28 / 4 = 7
therefore 2 blank tiles were added and the minimum number if rows is 7
Yes using multiplication facts the question can be solved.

Solving a linear equation, we will see that 109 attendees did not visit the concession stand.
How to find the number of attendees who did not visit the concession stand?
First, we know that the total number of surveyed people is 680.
Of these 680, we know that:
527 said that the concession stand prices are excessive.44 said that the concession stand prices are not excessive.x did not visit the concession stand.Now, the 3 numbers above should add up to the total number of surveyed people.
527 + 44 + x = 680
Solving that linear equation for x:
x = 680 - 527 - 44 = 109
We conclude that the number of attendees who did not visit the concession stand is 109.
