Answer:
x = -4, y = -3
Step-by-step explanation:
When you use graphing to solve a system of equations, the intersection point is the solution. Here, the coordinates of the intersection point or solution is: (-4, -3). Coordinates are mostly written like this: (x, y) Thus, the solution is:
(x, y)
(-4, -3)
x = -4
y = -3
Answer: the average number of cows per square mile is 37.5, the nearest whole number is 38.
Step-by-step explanation: 48 x 5^6 equals to 750,000 cows spread in (32 x 5^4) 20,000 square miles of land. By dividing 750,000 by 20,000 you get the average number of cows per square mile.
Answer:
3/26
Step-by-step explanation:
The face cards are: Jack, Queen, and King. There are only three face cards for each of the 4 suits.
Among the 4 suits, two of them are red: diamonds and hearts. And, each of these two has 3 faces. That means that in a deck of 52 cards, there are 2 * 3 = 6 cards that are both red cards and face cards.
Probability is (# times specific event can occur) / (# times any general event will occur).
Here, the specific event is drawing a card that is both red and a face card (of which there are 6 ways), and the general event is drawing a card (of which there are 52 ways):
P(draw a card that is both red and a face card) = 6/52 = 3/26
