4math problem

1. y=-6x-14
-x-3y=-9

2. -5x+2y=-11
5x-3y=14

3. x+10y=-16
x-6y=16

4. -12x-y=15
6x-2y=-30

Step-by-step explanation:

1)y=-6x-14   (i)

-x-3y=-9   (ii)

Substitution method:

Substitute y  value in equ (i)

-x -3*(-6x-14) = -9

-x - 3*-6x -3*(-14)= -9

-x + 18x + 42 = -9

17x = -9 -42

17x = -51

x = -51/17

x = -3

Substitute x value in equation (i)

y = -6*-3 -14

y =18-14

y = 4

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
