<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>
Answer:
3.25 = 3 1/4
Step-by-step explanation:
The decimal 3.25 would be written a couple of different ways as a fraction: 3.25 = 3 1/4 as a mixed number. 3.25 = 13/4 as an improper fraction.
The correct answer is B) 1/13.
P(Jack of spades given spades) = P(J|spades) = P(spades and J)/P(spades)
There is 1 Jack of spades out of 52 cards; P(spades and J) = 1/52
There are 13 spades out of 52 cards; P(spades) = 13/52 = 1/4
1/52 ÷ 1/4 = 1/52 × 4/1 = 4/52 = 1/13
Slope: -4
X-Intercept: -.5
Y-Intercept: -2
