In order to find x, we apply the trigonometric ratio

Given the rectangle ABCD, whose vertices are:
[tex]A\mleft(4,1\mright),B\mleft(2,3\mright),C\mleft(5,6\mright),D\mleft(7,4\mright)[/tex]You can apply the transformations shown in each option, in order to determine all the transformations that will carry the figure onto itself:
• First option:
By definition, the rule for a rotation of 270 degrees counterclockwise is:
[tex](x,y)\rightarrow(y,-x)[/tex]And the rule for a rotation of 90 degrees counterclockwise is:
[tex](x,y)\to(-y,x)[/tex]Therefore, you can choose any vertex of the rectangle and apply the first rule and then the second rule:
[tex]A\mleft(4,1\mright)\rightarrow A^{\prime}\mleft(1,-4\mright)\rightarrow A^{\doubleprime}\rightarrow(4,1)[/tex]Notice that the coordinates of point A'' are equal to the original point A.
• Second option:
The rule for a translation of 10 units left and 5 units down is:
[tex](x,y)\rightarrow(x-10,y-5)[/tex]And the rule for a translation of 10 units right, and 5 units up is:
[tex](x,y)\rightarrow(x+10,y+5)[/tex]Then, applying the transformations indicated, you get:
[tex]\begin{gathered} A\mleft(4,1\mright)\rightarrow A^{\prime}(4-10,1-5)=A^{\prime}(-6,-4) \\ \\ A^{\prime}(-6,-4)\rightarrow A^{\prime\prime}(-6+10,-4+5)=A^{\doubleprime}(4,1) \end{gathered}[/tex]Notice that point A'' and point A are equal.
• Third option:
The rule for a reflection across the y-axis is:
[tex](x,y)\rightarrow\mleft(-x,y\mright)[/tex]Then, applying that transformation and then applying the rule for a rotation of 270 degrees counterclockwise about the Origin (shown in the explanation of the First option), you get:
[tex]A(4,1)\rightarrow A^{\prime}(-4,1)\rightarrow A^{\doubleprime}(1,4)[/tex]The points A and A'' are different.
• Fourth option:
The rule for a reflection across the x-axis is:
[tex](x,y)\rightarrow(x,-y)[/tex]For a translation of 5 units left is:
[tex](x,y)\rightarrow(x-5,y)[/tex]And for a translation of 5 units right:
[tex](x,y)\rightarrow(x+5,y)[/tex]Therefore, knowing those rules and also knowing the rule for a reflection across the y-axis, you can apply all the transformations indicated in the third option, you get:
[tex]A\mleft(4,1\mright)\rightarrow A^{\prime}\mleft(4,-1\mright)\rightarrow A^{\doubleprime}(4-5,-1)=A^{\doubleprime}(-1,-1)[/tex][tex]A^{\doubleprime}(-1,-1)\rightarrow A^{\doubleprime}^{\prime}(1,-1)\rightarrow A^{\doubleprime\prime^{\prime}}(6,-1)[/tex]Notice that the points A and A'''' do not have the same coordinates.
• Fifth option:
Knowing the rule for a reflection across the y-axis, and knowing that to translate a point 9 units right you must add 9 to the x-coordinate of the points, you get:
[tex]A\mleft(4,1\mright)\rightarrow A^{\prime}\mleft(-4,1\mright)\rightarrow A^{\doubleprime}(-4+9,1)=A^{\doubleprime}(5,1)[/tex]Notice that the points A and A'' do not have the same coordinates.
Hence, the answers are:
• First option.
,• Second option.

Answer:

−6x(−4/3)
=(−6/1)(−4/3)
=(−6)(−4)/(1)(3)
=24/3
=8x
Answer:
8x
Step-by-step explanation:
So, you have -6x(-4/3)
-4/3 could be written as a division problem, or we could just call it a fraction. And -6x is the same thing as -6x/1, so we can write that as a fraction as well. So, we multiply.
Numerators: -4 times -6=24, and we throw the x on, so we have 24x
Denominators: 3 times 1 = 3, so the denominator is 3
So, we have 24x/3, which simplifies to 8x

Matt has five times as many stickers as David. How many stickers must Matt give David so that they will each have 180 stickers?
Answers
Matt must give David 120 stickers
Explanation:Let the number of stickers that Matt has be m
Let the number of stickers that David has be d
If each of them ends up with 180 stickers each:
the total number of stickers available = 2(180)
the total number of stickers available = 360
Matt has 5 times has many stickers has David
m = 5d
Note that:
Matt's stickers + David's stickers = 360
m + d = 360
5d + d = 360
6d = 360
d = 360/6
d = 60
David has 60 stickers
m = 5d
m = 5(60)
m = 300
Matt has 300 stickers
The number of stickers Matt must give David so that they will each have 180 stickers = 300 - 180 = 120
Matt must give David 120 stickers so that they will each have 180 stickers

How to solve a system of equations using Cramer's rule?The solution of a system of equations using Cramer's rule is based on the use of determinants of matrices.
In the context of this problem, the system is:
x + 2y = 8.-3x - 2y = 12.The matrix for the system is:
M =
[1 2]
[-3 - 2]
The determinant of the matrix M of the system is given as follows:
|M| = -2 + 6 = 4.
(using the standard procedure to obtain the determinant of a 2 x 2 matrix).
To find the matrix for x, the x-coefficients are replaced by the right-side coefficients, that is, the results of the operations, hence:
Mx =
[8 2]
[12 - 2]
Then the determinant is:
|Mx| = 8(-2) - 2(12) = -16 - 24 = -40.
The solution for x is:
x = -40/4 = -10.
To find the matrix for y, the y-coefficients are replaced by the right-side coefficients, that is, the results of the operations, hence:
My =
[1 8]
[-3 12]
The determinant is:
|My| = 12 - (-3)(8) = 12 + 24 = 36.
Hence the solution is:

BEA = 180 - BEF ---- Angle on a straight line
BEA = 180 - 4x
ABE = 180 - EBC ---- Angle on a straight line
ABE = 180 - 6x
The sum of angles in a triangle is 180
So, we have
BAE + BEA + ABE = 180
This gives
2x + 180 - 4x + 180 - 6x = 180
Evaluate the like terms
-8x = -180
Divide both sides by -8
x = 22.5
Hence, the measure of x is 22.5
