1. Are the following equations parallel, perpendicular or neither?

3 + 2 = 74 and 9 − 6 = 15

A. parallel
B. perpendicular
C. neither

2. Are the pairs of lines below parallel, perpendicular, or neither?

4x - 9y= 8 and 18x+ 8y= 7

A. parallel
B. perpendicular
C. neither

answer:

1. is neither

2.parallel

Step-by-step explanation:

hope it helps

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

to complete this square you have to rotate about the origin 270 degrees clockwise.
