To do this you need to put it in function form.
Here's the work
2y-3x = 8
2y-3x = 8
+3x +3x
2y = 3x+8
/2. /2
y = 3/2x + 8
To find perpendicular you multiply the slope the the opposite reciprocal.
y = -2/3x + 8
Then the +8 doesn't really matter now
Slope that is perpendicular is -2/3x
The answer is either a or d but we know she did all of this for more than 52 minutes.
A = b - 2
a - 3b = 22
(b - 2) - 3b = 22
b - 2 - 3b = 22
-2 - 2b = 22
-2b = 24
-b = 12
b = -12
a = b - 2
a = -12 - 2
a = -14
Solution set {-14, -12}
Step-by-step explanation:
There are 21 socks in total. Only 7 of them are white.
When you pick your 1st sock, you have a 7/21 chance to get white.
When you pick your 2nd sock, you have a 6/21 chance to get another white, since you already picked a white.
So the probability to get a pair of white socks is 2/21.
