Answer:
Heads: 5/8
Tails: 3/8
Step-by-step explanation:
The probability of getting tails is 375/1000 OR 3/8.
The probability of getting heads is 625/1000 OR 5/8.
Answer:
(2, -16).
Step-by-step explanation:
(x - 6)(x + 2)
Convert to vertex form:
Expanding the parentheses we have:
x^2 + 2x - 6x - 12
= x^2 - 4x - 12
Completing the square:
= (x - 2)^2 - 4 - 12
= (x - 2)^2 - 16
So the vertex is (2, -16),
Answer:
1. 12
2. 0.04
3. 196
Step-by-step explanation:
1. 12*12= 144
2. 1/25= 0.04
3. (11-8)^2= 3^2= 9
Answer:
Step-by-step explanation:
Try to get x alone on one side
Add nine to both sides
18x - 9 = 5 + 12x
+ 9 + 9
Subtract 12x from both sides
18x = 14 + 12x
-12x -12x
Now that you have x alone on one side divide both sides by 6
6x = 14
