Answer:
y = -x/2 + 1/2 or
y = -1/2 x + 1/2
(these are equivalent)
Step-by-step explanation:
Slope-intercept form is:
y = mx + b
So we have to get the y all by itself on the left.
2y + x = 1
Subtract x from both sides.
2y = 1 - x
Divide both sides by 2. Divide all the terms by 2.
2y/2 = 1/2 - x/2
Simplify.
y = 1/2 - x/2
Rearrange the terms on the right side so that the x term is first and the constant is last.
y = -x/2 + 1/2
I think this is a good, reasonable and correct answer. But maybe you really want to see that m number (the slope) out in front of the x. Then you can write is as:
y = -1/2 x + 1/2
Answer:
41 over 24
Step-by-step explanation:
7 2/3 can be "translated" into 3 times 7 plus 2 which is 22, so now it's 22 over 3.
5 5/8 can be "translated" into 8 times 5 plus five is forty five, so now it's 45 over 8.
We now need a common denominator.
Multiples of 8: 8, 16, 24, 32
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24
24 are both multiples of 8 and 3.
Now you have to multiply 22 and 8 because 3 times 8 equals 24 and so you have to do it to the numerator.
22*8=176
Now you have to multiply 45 and 3 since 8 times 3 equals 24 and so you have to do it to the numerator, too.
45*3=135
All you have to do now is subtract 176 from 135 which is 41
Answer: p = 1/25
Step-by-step explanation:
Ok, you know that the probability of rolling a six is p = 1/5
now, if you want to have two sixes, then you have two events with a probability of 1/5.
And as you know the joint probability for two events is equal to the product of the probabilities, then the probability of rolling two sixes is:
p = (1/5)*(1/5) = 1/25.
Decreasing in quantity according to the law is the definition of exponential decay. but what are the choices you can chose from?
