4x -9y= -42
x+5y=4
solve by elimination

x = -6 and y = 2

Step-by-step explanation:

4x-9y = -42

x+5y = 4

4x-9y = -42

4x + 20y = 16

Take them away from each other.

-29y = -58

Find what one y is by dividing.

-58 / -29 = 2

y = 2

Substitute back into original.

x + 10(5*y) = 4

Take 10 away to find x.

x = -6

Check if answer is correct.

4x - 9y = -42

-24 - 18 = -42

Final x = -6 and y = 2

step-by-step explanation:

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
