xxTIMURxx [149]3 years ago
3 0

Answer:

7

Step-by-step explanation:

Using the definition

nP_{r} = \frac{n!}{(n-r)!}

where n! = n(n - 1)(n - 2)..... 3 × 2 × 1

Then

7P_{1} = \frac{7!}{(7-1)!} = \frac{7!}{6!} ← cancel out the multiples 6 ×5 × 4 × 3 × 2 × 1 , then

7P_{1} = 7

Write an equation of the line that passes through (18, 2) and is parallel to the line 3y - x = -12
GarryVolchara [31]
First you need to find the slope.
You do this by adding x to both sides to get 3y=x-12
Then, you divide by three on both sides to get y=1/3x -4
to find the new y intercept you insert the point and the slope in the equation
2=1/3(18)+b 
You multiply 1/3 and 18 to get 2=6+b
Finally you subtract 6 on both sides to get -4=b.
This means that the equation of the line is the same as the given line
