The first and the last are correct.
Answer:
slope = - 4
Step-by-step explanation:
Calculate the slope m using the slope formula and any 2 ordered pairs from the table.
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 8) and (x₂, y₂ ) = (- 1, 4) ← 2 points from the table
m =
=
= - 4
Answer:
The people can sit in 1,152 possible ways if all men must sit together and all women must sit together.
Explanation:
The 4 men must sit together.
Number of ways to arrange the 4 men together
= 4! = 4 x 3 x 2 x 1 = 24
Similarly, the 4 women must sit together.
Number of ways to arrange the 4 women together
= 4! = 4 x 3 x 2 x 1 = 24
Now the 8 chairs are placed in a row. There are 2 ways to arrange the men and women: either the men must sit in the first 4 chairs and women in the last 4 chairs, or the women must sit in the first 4 chairs and men in the last 4 chairs.
Hence, total number of ways to arrange the 8 people
= 24 x 24 x 2
= 1,152
Answer:
School X has 8 points and School Y has 2 points
Step-by-step explanation:
From first sentence
X - 6 = Y
From second sentence
X = 4Y
Hence substitute equation 1 into equation 2
4Y - 6 = Y
Y = 2
X = 4 x 2 = 8
