Find x. (The picture has the info)
Answer:
X=5
Step-by-step explanation:
3x+9 is twice of 12 (24). 24-9=15, and 3*5=15, so x=5.
ABCD is a parallelogram
M is the midpoint of CB
N is the midpoint of AB
DA = a
DC = c
a) find, in terms of a and c, the vector of MN
b) show that CA is parralel to MN
Answer:
Part a)
MN = 0.5a-0.5c
Part b)
MN=0.5a-0.5c
CA=a-c
CA is parallel to MN because 2×MN = CA.
Step-by-step explanation:
Part a = We know that ABCD is a parallelogram (stated), thus opposite sides must be equal. So given that DA = a, CB = a, DC = c, AB = C.
MN = MB+BN, so as M is the midpoint of CB then MB = 1/2 a and as we are going against AB (we are doing BN) then it will be -0.5c as N is the midpoint of AB.
Part B= More of a mathswatch error, where you have to quite literally put the precise answer. CA = CD+DA so -c (as we are going the opposite way to DC) + a.
CA = -c+a
Now CA is a multiple of MN. But Mathswatch prefers if you say that CA is parallel to MN because MN times 2 is equal to CA
In this exercise we have to use the knowledge of parallelogram and vectors to give the values of each one of them, like this:
A) MN = 0.5a-0.5c
B)CA is parallel to MN because 2×MN = CA.
First, we have to remember the definition of parallelogram:
A polygon is any flat closed shape made of straight line segments. A parallelogram is a polygon with 4 sides in which sides that don't touch each other are parallel.A) We know that ABCD is a parallelogram, thus opposite sides must be equal. So given that:
[tex]DA = a,\\CB = a, \\DC = c, \\AB = C.[/tex]
[tex]MN = MB+BN\\MB = 1/2\\BN=-0.5c\\MN = 0.5a-0.5c[/tex]
B)Where you have to quite literally put the precise answer, so we have that:
[tex]CA = CD+DA \\CD=-c\\DA=a\\CA = -c+a\\[/tex]

Given a point translated from A(1,2) to B(4,4). If a point C at (0,0) is translated in the same way, what will be its new endpoints?
A.(−3,−2)
B.(3,2)
C.(2,2)
D.(3,3)
Answer:
B.(3,2)
Step-by-step explanation:
Point translated from A(1,2) to B(4,4).
This means that for x, we add 3 units(4 - 1 = 3), while for y, we add two units(4 - 2 = 2).
If a point C at (0,0) is translated in the same way, what will be its new endpoints?
0 + 3 = 3
0 + 2 = 2
So
B.(3,2)
Which one of the points A(5.2). B(6,-3) and C(4.7) is the mid-point of the other two? Check your answer by calculating two distances.
Answer:
A is the midpoint
Step-by-step explanation:
Given
A(5.2) B(6,-3) and C(4.7)
Required
Which is the midpoint
Midpoint is calculated using:
[tex](x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]
Testing A as the midpoint, we have:
[tex](5,2) = \frac{1}{2}(6+4,-3+7)[/tex]
[tex](5,2) = \frac{1}{2}(10,4)[/tex]
[tex](5,2) = (\frac{1}{2}*10,\frac{1}{2}*4)[/tex]
[tex](5,2) = (5,2)[/tex]
The above equation is true. Hence, A is the midpoint of B and C
If all entries of A and A^−1 are integers, prove that detA = 1 or −1.

Q10
∠1 = ∠5 = 180° - 144° = 36°∠2 = 56°∠3 = 180° - 56° = 124°∠4 = 144° - 56° = 88°∠5 = ∠1 = 36°Q11
∠1 = 35°∠2 = 180° - 35° = 145°∠3 = 90° - 35° = 55°∠4 = 180° - ∠5 = 180° - ∠3 = 180° - 55° = 125°∠5 = ∠3 = 55°Measure of angles for figure 1:
∠1=36∠2=56∠3=124∠4=88∠5=36Measure of angles for figure 2:
∠1=35∠2=145∠3=55∠4=125∠5=55The angle is formed by two rays at a common point of the two rays.
For given figure 1:
∠1+144=180 (Sum of angles on same side of transversal is 180°)
∠1=180-144
∠1=36
∠5+144=180(Sum of angles on a line is 180°)
∠5=180-144
∠5=36
Similarly, ∠3=180-56
∠3=124
∠4+36+56=180(Sum of all angles of a triangle is 180°)
∠4=180-36-56
∠4=88
∠2+36+88=180
∠2=56
Thus, measure of angles for figure 1 are ∠1=36, ∠2=56, ∠3=124, ∠4=88, ∠5=36.
For given, figure 2:
∠1=35(Alternate angle on same side of transversal are equal)
∠2=180-35
∠5=180-35-90(Sum of all angles of a triangle is 180°)
∠5=55
∠4+55=180(Sum of angles on a line is 180°)
∠4=180-55
∠4=125
Similarly, ∠2=180-35(Sum of angles on a line is 180°)
∠2=145
∠3=180-35-90(Sum of all angles of a triangle is 180°)
∠3=55
Thus, measure of angles for figure 2 are ∠1=35, ∠2=145, ∠3=55, ∠4=125, ∠5=55
