Answer with Step-by-step explanation:
The number of marbles are as under
3 red , 3 green , 1 Lavender total = 7
Now to select five marbles from a total of 7 marbles such that at least 2 marbles are included are the sum of the following cases:
1) We select 2 exactly 2 red marbles from 3 reds and the remaining 3 marbles are selected from 4 of other colours
Thus 
2)We select all the 3 red marbles and the remaining 2 are selected from the remaining 4 marbles

Thus the total number of ways are 
G(-1) = -1 - 2 + 1 -4
= -6
Answer:
Point-slope equations:
y - 5 = 4/3 (x - 6)
or
y - 1 = 4/3 (x - 3)
Step-by-step explanation:
Given two coordinate points (6, 5) and (3, 1)
Slope = (5 - 1)/(6 - 3) = 4/3
Point-slope equations:
y - 5 = 4/3 (x - 6)
or
y - 1 = 4/3 (x - 3)

For the first triangle x=70. 180-40 is 140. Divided that by 2 and you’d get 70.
The second triangle x=90. 180-45 is 135. 135-45 (the angle congruent to the other 45 degree angle) is 90.
The third triangle x=65. 180-50 is 130. 130 divided by two is 65.
Check all answers by adding all the angles of the triangle and make sure they equal 180
