Which statements are true about the ordered pair (7, 19) and the system of equations? {2x−y=−5x+3y=22

Select each correct answer.

A)The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.

B)The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.

C)The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.

D)The ordered pair (7, 19) is a solution to the system because it makes both equations true.

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.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

it is c, trust i got your back lol
