Which expressions are equivalent to -24 choose all dat apply please -6(-4)(-1) -1(-1)(-1)(24)
24 divided by 1 -240 divided by 10
-8(3)(-1) -2(-12)

2 & 4

Step-by-step explanation:

1)   -6(-4)(-1):

This one you would multiply one at a time. So -6 * -4 is -24 but then you multiply it by -1 so the answer is 24.

2)   -1(-1)(-1)(24):

Same thing one at a time. -1 * -1 is 1 then 1 *-1 is -1 and now we multiply it by 24 which is -24. This one is correct.

3)   24 divided by 1:

This one is simple 24 divided by 1 will still be 24 which is not what we want.

4)   -240 divided by 10:

This one is pretty much the same. -240 divided by 10 is -24. So this one is also correct.

5)   -8(3)(-1):

This one is like the first ones, one step at a time. -8 * 3 is -24 then times -24 and -1 which is 24. This is false.

6)   -2(-12):

This one is simple, -2 * -12 is 24 but it's not what we want so it's false.

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
