Answer: neither

Explanation:

y=1/5+2/5x

y=-1/5-2/5x

For it to be perpendicular the slopes have to be opposite reciprocals and they are not. For it to be parallel the slopes have to be the same and they too are not.

Circle A has center of (2, 8), and a radius of 2 and circle B has a center of (5, 4), and a radius of 10. What steps will help s
Viktor [21]

Answer:

1. Translate circle A using the rule (x − 3, y + 4).

4. Dilate circle A by a scale factor of 5

Step-by-step explanation:

we know that

All circles are similar figures

step 1

Translate the center of circle A to the center of circle B

we have

A(2,8) -----> B(5,4)

so

The rule of the translation is

(x,y) ----> (x+a,y+b)

(2,8) ----> (2+a,8+b)

2+a=5 ----> a=5-2=3

8+b=4 ---> b=4-8=-4

therefore

The rule of the translation is

(x,y) ----> (x+3,y-4)

step 2

Divide the radius of circle B to the radius of circle A to find out the scale factor

10/2=5

so

Multiply the radius of circle A by the scale factor to obtain the radius of circle B

therefore

Dilate circle A by a scale factor of 5

24<br> Find the value of x.<br> 4<br> (7x-1)<br> (6x - 1)
Lisa [10]

Answer:

x = 14

Step-by-step explanation:

Two lines given in the picture intersect each other at a point.

Given angles are the linear pair of angles.

Since, linear pair of the angles is supplementary,

(7x - 1)° + (6x - 1)° = 180°

(7x + 6x) + (- 1 - 1) = 180

13x -2 = 180

13x = 180 + 2

x = \frac{182}{13}

x = 14

Therefore, x = 14 will be the answer.
