Answer:

The firston one is a scale factor of two and the second one is a scale factor of three.

Step-by-step explanation:

You just look at the coordinates. (1,1):(2,2) and (4,0):(8,0) and then for the second one (-1,0):(-3,0) and (3,2):(9,6).

1x2=2

4x2=8

-1x3=-3

3x3=9

2x3=6

A pattern has 6 triangles to every 18 yellow triangles what is the ratio yellow triangles to blue triangles

polet [3.4K]

The ratio would be 3:1

( the 6 triangles are blue, which I’m pretty sure they are.)

Since there are 18 yellows and 6 blues, and the question calls for the ratio of the yellows to the blues, the ratio is 18:6. But you always have to simplify. The GCF is 6, so you would divide both of them by 6. The ratio is then 3:1.

A has the coordinates (–4, 3) and B has the coordinates (4, 4). If DO,1/2(x, y) is a dilation of △ABC, what is true about the im

loris [4]

Answer:

Coordinates of Vertices of triangle ABC are A (-4,3) , B(4,4) and C(1,1).

As, DO is Dilation of Δ ABC by Scale factor of $\frac{1}{2}$ .

Vertices of A' B'C' are

$A'=(\frac{-4}{2},\frac{3}{2})=(-2,\frac{3}{2}), B'=(\frac{4}{2},\frac{4}{2})=(2,2), C'=(\frac{1}{2},\frac{1}{2})$

So, Image Δ A'B'C' will be smaller than the Pre image Δ ABC.

The two triangles will be congruent.

AO is Dilated by a factor of half , so A'O' will be half of AO.

So, correct Statements are

1. AB is parallel to A'B'.

2.DO,1/2(x, y) =

The distance from A' to the origin is half the distance from A to the origin.

$OA=\sqrt{(-4)^2+3^2}=\sqrt{25}=5\\\\ O'A'=\sqrt{2^2+(\frac{3}{2})^2}=\frac{5}{2}=2.5$

The sum of x and y is eleven, their difference is five, what is the value of x and y?

REY [17]

Answer:

x = 8

y = 3

Step-by-step explanation:

x + y = 11

x - y = 5 Subtract

2x = 16

x = 16/2

x = 8

x + y = 11 Substitute x = 8

8 + y = 11 Subtract 8 from both sides

8-8+y =11-8

y = 3
