X=-2 I know because me smart lol
Answer:
D
Step-by-step explanation:
We know that four (4) queen cards are present in the deck of 52 cards. So, the probability of drawing one queen card is calculated as,
P = 1/13
The probability of not a queen is calculated as,
P' = 1 - P = 1 - 1/13 = 12/13
Step-by-step explanation:
Given,
6x - 5y = 10.5 .............. (1)
5x - 3y = -2 .................. (2)
Multiplying eq (1) by 3 and (2) by 5 then subtracting,
18x - 15y = 31.5
(-) 25x - 15y = -10
-----------------------------
-7x = 41.5
x = - 41.5 / 7 = -83 / 14
Inserting the value of x in eq (2)
5 * (-83 / 14) - 3y = -2
y = -129 / 14
x = -83 /14 and y = -129 /14
Answer:
Step-by-step explanation:
Y=2x-7, y=5x+4 goes in one solution
Y=-2x+3, y=2x-1 goes in one solution
Y=5x+4,y=5x-2 goes in no solution
Y=-2x+3,y=1/2x-7 goes in one solution
3y=-12+6,y=-4x+2 goes in infinitely many solutions
