A triangle ABC with vertices A(6,8) B(6,12) C(10,12) is rotated to 180. What are the coordinates of B
hichkok12 [17]
Assuming rotation is about origin, then
R180:  (x,y)->(-x,-y)

So
A(6,8)->A'(-6,-8)
B(6,12)->B'(-6,-12)
C(10,12)->C'(-10,-12)

If v is one-third of the quantity 3 less than u, how does v change if u is increasing?
kykrilka [37]

Answer:

v increases when u increases

Step-by-step explanation:

From the question, we have that

v = u - \frac{1}{3} * 3

v = u - \frac{3}{3}

v = u - 1

Take u = 1

v = u - 1

v = 1 - 1

v = 0

Take u = 2

v = u - 1

v = 2 - 1

v = 1

Take u = 10

v = u - 1

v = 10 - 1

v = 9

<em>This implies that an increment in u brings an increment in v</em>

Find the missing segment in the attached image
xz_007 [3.2K]

Answer:

The length of the missing segment is 24

Step-by-step explanation:

Given

The figure above

Required

Determine the missing segment

Let the missing segment be represented with x

Given that, there exist parallel lines between the two triangles;

The relationship between the sides of the triangles is as follows;

\frac{15}{x} = \frac{15+5}{8+x}

\frac{15}{x} = \frac{20}{8+x}

Cross Multiply

15 * (8 + x) = 20 * x

Open bracket

15*8 + 15 * x = 20 * x

120 + 15x = 20x

Subtract 15x from both sides

120 + 15x -15x= 20x-15x

120 = 20x-15x

120 = 5x

Divide both sides by 5

\frac{120}{5} = \frac{5x}{5}

\frac{120}{5} = x

24 = x

x = 24

Hence, the length of the missing segment is 24
