The hard drive on your computer has a capacity of 160 gigabytes (GB). You have used 122 GB. You want to save some home videos to your hard drive. What are the possible sizes of the home video collection you can save? If u represents the amount of space used, write an inequality that determines a, the amount of space available.

A. at most 282 GB; a ≤ 160 + u
B. at least 38 GB; a ≥ 160 − u
C. at most 38 GB; a ≤ 160 − u
D. at least 282 GB; a ≥ 160 + u

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

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
