What is the solution to the system of equations? y=-3-2. 5x+2y=15

x=-19

y=55

Step-by-step explanation:

y=-3x-2.

5x+2y=15

substitute y into 5x+2y =15

5x +2 (-3x-2) = 15

distribute

5x -6x-4 = 15

combine like terms

-x-4 =15

add 4 to each side

-x-4+4 = 15+4

-x=19

multiply by -1

x = -19

now lets find y

y= -3x-2

y = -3(-19) -2

y = 57-2

y =55

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
