The slope of the given line is the coefficient of x, 3/5. The slope of the perpendicular line will be the negative reciprocal of that: -1/(3/5) = -5/3.
The point-slope form of the equation for a line of slope m through point (h, k) can be written ...
... y = m(x -h) +k
For your point and the slope found above, this becomes
... y = (-5/3)(x -15) -5
When x=0, this is
... y = (-5/3)(-15) -5 = 20
The y-intercept is 20.
The formulas for conditional probability are:
.
Since
and
, you have the equation
.
Therefore,
.
Answer: The correct choice is D.
You will make 1224-1000=224
then you will divide 224 by two it will be 112
you will add 112 to the less one
112+1000=1112
Answer:
18
Step-by-step explanation:
This is because when you find the prime factors, you can take out the ones that they have together.
In this case:
9 - 3 * 3
6 - 3 * 2
2 - 2
So notice that each number has a maximum of 2 3s and 1 2, thus, you can multiple 3 * 3 * 2
