Answer:
D y=2/3 x +1
y= -3/2 x+2
Step-by-step explanation:
Perpendicular lines have slopes that multiply to -1
The equations are written in slope intercept form
y = mx+b where m is the slope
A 1/5* 5 = 1 not perpendicular
B 2/3 * 3/2 = 1 not perpendicular
C -1/5 * -5 = 1 not perpendicular
D 2/3 * - 3/2 = -1 perpendicular
Answer:
10
Step-by-step explanation:
im not sure if its correct but area is the area around the trapezoid and i added them
So we know the slope has to be -3 and the y intercept is 2. y intercept looks like (0,2). since we know this we automatically can rule out B since it has (0,0).
let’s find the slope of A
-9- -5
-3- - 1
the slope= -4/-2= 2
we know it’s not A because the slope is not -3
let’s find the slope of C
-17- -8
-5- -2
slope= -9/-3=3
we know it’s not C because the slope is not -3. we could directly assume that D is the answer no but we’ll still find the slope just to be sure
let’s find the slope of D
14-8
-4- -2
slope=6/-2= -3
the answer is D!!
First off, Parallel lines are two lines that lie within the same plane and never intersect, So the undefined terms that are needed to define a parallel line are Lines, planes.
Answer:
Multiple answers
Step-by-step explanation:
The original urns have:
- Urn 1 = 2 red + 4 white = 6 chips
- Urn 2 = 3 red + 1 white = 4 chips
We take one chip from the first urn, so we have:
The probability of take a red one is : 
(2 red from 6 chips(2/6=1/2))
For a white one is: 
(4 white from 6 chips(4/6=(2/3))
Then we put this chip into the second urn:
We have two possible cases:
- First if the chip we got from the first urn was white. The urn 2 now has 3 red + 2 whites = 5 chips
- Second if the chip we got from the first urn was red. The urn two now has 4 red + 1 white = 5 chips
If we select a chip from the urn two:
- In the first case the probability of taking a white one is of:
= 40% ( 2 whites of 5 chips) - In the second case the probability of taking a white one is of:
= 20% ( 1 whites of 5 chips)
This problem is a dependent event because the final result depends of the first chip we got from the urn 1.
For the fist case we multiply :
x = 
= 26.66% ( the probability of taking a white chip from the urn 1, the probability of taking a white chip from urn two)
For the second case we multiply:
x = 
= .06% ( the probability of taking a red chip from the urn 1, the probability of taking a white chip from the urn two)
