Best explained answer will be marked brainliest. A lock company wants to create locks that are reliable. It has the option of either making a 5-number combination lock using the numbers 1-20, in which no number can be repeated, or a 4-number combination using the numbers 1-30, in which the numbers can repeat. Which lock type would be more difficult to hack by random chance?

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

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.

x = 3 ± √(5+y)

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
