Persamaan lingkaran dengan pusat (-1, 1) dan melalui (2, -3) adalah ….   a. x2 + y2 - 2x + 2y  = 21 b. x2 + y2 - 2x + 2y  = 25 c. x2 + y2 - 2x + 2y  = 23 d. x2 + y2 + 2x - 2y  = 23 e. x2 + y2 + 2x - 2y + 5 = 0

idk bring the function back   im not smart

step-by-step explanation:

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
