P(5,2) = n! /(n-r)!
n = 5, r = 2:
= (5 x 4 x 3 x 2 x 1 ) / 3 x 2 x 1
Cancel out common factors:
= 5 x 4 = 20
The answer is 20.
Answer:
The order pair (4,-5) is <u>NOT </u>a solution of the inequality
Step-by-step explanation:
2)
Plug in to see if the order pair (4,-5) is a solution of the inequality
y - 8 < - 4x
-5 - 8 ? -4( 4)
- 13 > -16
So answer:
The order pair (4,-5) is <u>NOT </u>a solution of the inequality
Answer:
Incorrect
Step-by-step explanation:
The correct answer is A.
The slope-intercept form is y-y₁=m(x-x₁)
The problem with B is that if you take out the coordinates for x₁ and y₁, you get the coordinates (1,4). This coordinate does not land on the line.
The coordinates for A is (-1,4). This point does land on the line.
