Answer:
x= -2
Step-by-step explanation:
7x+26+5x=2
7x+5x=12x
12x=2-26
12x= -24
(divide both sides by 12)
x= -2
X ^ 2 - 9
= x ^ 2 - 3 ^ 2
It turns into 3 ^ 2
Because 3 ^ 2 = 9
The final answer is
= ( x + 3 )( x - 3 )
remember the formula :
a^2 - b^2 =(a+b)(a-b)
Answer:
So the slope is -8/3
Step-by-step explanation:
to find the slope you have to use m = y2-y1/x2-x1
so lets plug in our numbers
m = - 4- 4/5-2
= -8/3
So the slope is -8/3
The probability of getting heads on the first toss is 1/2 .
Then, the probability of getting heads on the second toss is 1/2 .
Then, the probability of getting heads on the third toss is 1/2 .
The probability of all three things happening is ...
(1/2) x (1/2) x (1/2) = 1/8 = 0.125 = 12.5% .
