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

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
