Which statements are true about the ordered pair (−4, 0) and the system of equations? {2x+y=−8x−y=−4

Reil [10]

<span>Selections (a, b, d) are the most correct answers. To begin, 2x is equal to -8 when x is (-4). Adding 0 to this (for y) gives -8, which is the answer for the first equation. Doing the same for the second equation gives (-4 - 0) = -4, which shows that the second equation is also correct. Since both equations are satisfied by this ordered pair, it shows that the pair (-4,0) is a solution to the entire system.</span>

What number must 200 be multiplied by to make it a perfect square

Juliette [100K]

Answer:

Step-by-step explanation:

Thus, we must multiply 200 by 2, so that the product becomes a perfect square. 400 is asquare of 20. So, the least number is 2, by which 200 must be multiplied so that the product becomes a perfect square.

A box contains 6 identically sized, solid-colored balls. one ball is green, 2 are yellow, and 3 are red. a ball is drawn at rand

WINSTONCH [101]

When you draw the first ball, you have three positive outcomes (the three red balls) and 6 possible outcomes (any of the six balls in the box).

This means that the probabilty of getting a red ball in the first draw is

$\frac{3}{6} = \frac{1}{2}$

since you return the first drawn ball to the box, the second drawn takes place with the same conditions as the first, exept this time you're looking for a green ball, and thus you only have one positive outcome. So, the probability of getting a green ball is

$\frac{1}{6}$

The probability of two independent events occuring one after the other is the product of the two probabilities, so the answer to your question is

$\frac{1}{2}\cdot\frac{1}{6} = \frac{1}{12}$
