Carly withdraws $18 from her bank account. Which number line represents this amount? A number line going from negative 20 to positive 20. A point is at 18. A number line going from negative 20 to positive 20. A point is at 12. A number line going from negative 20 to positive 20. A point is at negative 12. A number line going from negative 20 to positive 20. A point is at negative 18.PLEASE HELP QUICKLY!!!

A withdrawal is taking money out which is a negative value.

She took $18 out so it would be written as -18.

The answer is:

A number line going from negative 20 to positive 20. A point is at negative 18.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
