Reflections In The Coordinate Plane
Reflect over the x-axis:When we reflect a point over the x-axis, the x-coordinate remains the same, but the y-coordinate is mapped to its opposite.
The reflection of the point (x,y) over the x-axis is the point (x,-y).
Reflect over the y-axis:When reflecting a point over the y-axis, the y-coordinate remains the same, but the x-coordinate is mapped to its opposite (its sign is changed).
The reflection of the point (x,y) across the y-axis is the point (-x,y).
Point A is at (-11,-7). When reflected over the x-axis, it maps to Point B located at B(-11,7).
Point B is now reflected over the y-axis and maps to C(11,7).
Answer: B(-11,7) C(11,7)

Example 24 In a school there are 20 teachers who teach mathematics or physil
these, 12 teach mathematics and 4 teach both physics and mathematics. How Ex
teach physics ?
Answer:
The number of teachers who teach physics n(P) = 12
Step-by-step explanation:
Step(i):-
Given that the number of teachers who teach mathematics or physics
n(MUP) = 20
Given that the number of teachers who teach mathematics
n(M) = 12
Given that the number of teachers who teach both mathematics and physics
n(M∩P) = 4
Step(ii):-
By using n(A∪B) = n(A) + n(B) - n(A∩B)
n(M∪P) = n(M) +n(P) - n(M∩P)
20 = 12 + n(P) - 4
20 -12 +4 = n(P)
n(P) = 12
Final answer:-
The number of teachers who teach physics n(P) = 12

skew-symmetric 3 x 3 matrices form as subspace of all 3 x 3 matrices and find a basis for this subspace.
Answer:
a) ∝A ∈ W
so by subspace, W is subspace of 3 × 3 matrix
b) therefore Basis of W is
={ [tex]{\left[\begin{array}{ccc}0&1&0\\-1&0&0\\0&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&1\\0&0&0\\-1&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&0\\0&0&1\\0&-1&0\end{array}\right][/tex]}
Step-by-step explanation:
Given the data in the question;
W = { A| Air Skew symmetric matrix}
= {A | A = -A^T }
A ; O⁻ = -O⁻^T O⁻ : Zero mstrix
O⁻ ∈ W
now let A, B ∈ W
A = -A^T B = -B^T
(A+B)^T = A^T + B^T
= -A - B
- ( A + B )
⇒ A + B = -( A + B)^T
∴ A + B ∈ W.
∝ ∈ | R
(∝.A)^T = ∝A^T
= ∝( -A)
= -( ∝A)
(∝A) = -( ∝A)^T
∴ ∝A ∈ W
so by subspace, W is subspace of 3 × 3 matrix
A ∈ W
A = -AT
A = [tex]\left[\begin{array}{ccc}o&a&b\\-a&o&c\\-b&-c&0\end{array}\right][/tex]
= [tex]a\left[\begin{array}{ccc}0&1&0\\-1&0&0\\0&0&0\end{array}\right][/tex] [tex]+b\left[\begin{array}{ccc}0&0&1\\0&0&0\\-1&0&0\end{array}\right][/tex] [tex]+c\left[\begin{array}{ccc}0&0&0\\0&0&1\\0&-1&0\end{array}\right][/tex]
therefore Basis of W is
={ [tex]{\left[\begin{array}{ccc}0&1&0\\-1&0&0\\0&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&1\\0&0&0\\-1&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&0\\0&0&1\\0&-1&0\end{array}\right][/tex]}

Select all the ways that describe the graph of the function in interval 2.
Answer:
Options (2) and (3)
Step-by-step explanation:
Slope of line segment is given by the formula,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Here, the line given in the graph has the Rise as negative (Since, segment is slanting down) and Run as positive.
Therefore, slope of the segment is negative which describes that the function is decreasing in the interval 2.
Options (2) and (3) will be the correct options.
10, 4. -2, -8 in an explicit formula
Answer:
16 - 6n
Step-by-step explanation:
10 , 4 , -2 , - 8 .....
This is arithmetic sequence
first term = 10
Common difference = 2nd term - first term
d = 4 - 10
d = -6
nth term = a₁ + (n -1)d
= 10 + (n - 1)*(-6)
= 10 + n*(-6) - 1*(-6)
= 10 - 6n + 6
= 10 + 6 - 6n
= 16 - 6n

Select all the sums that are positive.
A. –5 + (–2)
B. 5 + (–2)
C. –3 + 4
D. 0 + (–3)
E. –2 + 4
Answer:
The positive sums are:
B. 5 + (–2)
C. –3 + 4
E. –2 + 4
Step-by-step explanation:
We can simply observe the sums to conclude that the sum will be positive or negative.
A. –5 + (–2)
We can see that both numbers are negative, the sum of two nu=egative numbers is also negative.
-5+(-2) = -5-2 = -7
B. 5 + (–2)
The number with greater magnitude is positive so the sum will also be positive.
5 + (–2) = 5-2 = 3
C. –3 + 4
The number with greater magnitude is positive so the sum will also be positive.
-3+4 = 1
D. 0 + (–3)
The number with greater magnitude is negative so the sum will also be negative.
= 0-3 = -3
E. –2 + 4
The number with greater magnitude is positive so the sum will also be positive.
-2+4 = 2
Hence,
The positive sums are:
B. 5 + (–2)
C. –3 + 4
E. –2 + 4
