Need asap will give brainliest ! solve the system of equations x-2y=3 3x+y= -5 a) (-2,-1) b) (-1,-2) c) (7,2) d) (2,7)

B) (-1,-2)

Step-by-step explanation:

x-2y=3

3x+y=-5

The first step would be to rearrange an equation in order to be able to use the Substitution method.  Personally, I believe it is easiest to rearrange the first one:

x-2y=3

x=3+2y

Now that the equation has been rearranged, the Substitution method can be used:

3(3+2y)+y=-5

9+6y+y=-5

9+7y=-5

7y=-14

y=-2

Now that we have solved for y, we already kind of know the answer, since only one option has this y value, but it doesn't hurt to double check by plugging in "y" into an equation:

x=3+2(-2)

x=3-4

x=-1

The solution for the system of equation would be (-1,-2)

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
