The "successful" region has half the size of the whole triangle, so by similar triangles, the probability that the area of triangle XYD is at most 12 is 1/4.
From the first equation
6x - y = 1
6x - y - 1 = 0
6x - 1 = y
Substituting we get
4x - 3(6x - 1) = -11
Just times it :)) and take the Fractions and put them in simplest form example 2 and 1/2 take the 2 and 2 times it you get 4 plus the 1 5 over 2
Answer:
b= 6/5
b = 1 1/5
Step-by-step explanation:
We can solve this using cross products
(3b-4) (b-2)
--------- = ---------
4 8
8* (3b-4) = 4*(b-2)
Distribute
24b -32 = 4b -8
Subtract 4b from each side
24b-4b -32 = 4b-4b-8
20b -32 = -8
Add 32 to each side
20b -32+32 = -8 +32
20b =24
Divide each side by 20
20b/20 = 24/20
b= 24/20
Dividing the top and bottom by 4
b = 6/5
b = 1 4/20
=1 1/5
