Answer:

left 2 units, up 3 units

Step-by-step explanation:

(x-2, y+3)

-2 means 2 to the left

+3 means 3 up

So it would be left 2 units, up 3 units.

Answer:

<h3>left 2 units </h3><h3>up 3 units </h3><h3 />

Step-by-step explanation:

Rule:

If  x+b   right in b units

if  x-b    left   in b untits

if  y+b    up   in  b units

if  y-b  down in  b  units

You don 't have to use this rule if you know that on the Ox axis the line goes horizontally (the abscissa axis); And on the Oy axis vertically (the ordinate axis)

Then :

x-2    left in 2 units

y+3   up  in  3 units

What is the slope of the line segment? <br> a 1/4<br> b -1/4<br> c 4<br> d 4
galina1969 [7]

to get the slope of any line, we can simply use two points off of it, for this one, say (3,12) and (4,16)

\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{12})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{16}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{16-12}{4-3}\implies \cfrac{4}{1}\implies 4

The coordinates of the vertices of triangle ABC are A(3,6), B(6, 3), and C(9, 9). If triangle ABC Is dilated by 1/3x and 1/3y to
katovenus [111]

Answer:

A' =  (1,2)

B'=(2,1)

C' =(3,3)

Step-by-step explanation:

Given

A = (3,6)

B = (6,3)

C = (9,9)

Scale = \frac{1}{3}

Required

Determine the vertices of ABC

If truly the question asks for the vertices of ABC, then the vertices are:

A = (3,6)   B = (6,3)   C = (9,9)

However, I'm quite sure that's not the requirement of the question. So, I'll solve for A'B'C'

To do this, we simply multiply the vertices of ABC by the scale of dilation.

(A'B'C') = Scale\ Factor * (ABC)

A' = \frac{1}{3} * A

A' = \frac{1}{3} * (3,6)

A' =  (\frac{3}{3},\frac{6}{3})

A' =  (1,2)

B' = \frac{1}{3} * B

B' = \frac{1}{3} * (6,3)

B' = (\frac{6}{3},\frac{3}{3})

B'=(2,1)

C' = \frac{1}{3} * C

C' = \frac{1}{3} * (9,9)

C' = (\frac{9}{3},\frac{9}{3})

C' =(3,3)

Which set of three numbers could be the side lengths of a triangle?
spin [16.1K]

Answer:

The correct option is C.

Step-by-step explanation:

In a triangle, then sum of two smaller sides is greater than the length of third greatest side.

Let, in a triangle ABC, If the length of sides are a, then

c

In option A,

8\nless 2+4

Therefore option A is incorrect.

In option B,

6\nless 2+4

Therefore option B is incorrect.

In option C,

7

Therefore option C is correct.

In option D,

9\nless 3+5

Therefore option D is incorrect.
