(a) How many ways are there to arrange 3 people in a line (order matters) using a group of 5 people?
mart [117]

Answer:

60.

Step-by-step explanation:

This is a permutation exercise because order matters. The formula is n!/(n-r)!. In this case n=5 and r=3 so,

5!/(5-3)! = 5!/2! = 5!/2 = (5*4*3*2*1)/2 we can simplify the 2 and obtain 5*4*3= 60.

Answer:

Parallel: y = -5x - 34 ; Perpendicular: y = 1/5x - 14/5

Step-by-step explanation:

Lines that are parallel have the same slope. Lines that are perpendicular have opposite reciprocal slopes. (Ex. 1/3 ⇒ -3)

We need to substitute the given values into the point-slope form equation.

Parallel:

y + 4 = -5(x + 6)

y + 4 = -5x - 30

y = -5x - 34

Perpendicular:

y + 4 = 1/5(x + 6)

y + 4 = 1/5x + 6/5

y = 1/5x - 14/5

What is the y-intercept of f–1(x)?
wolverine [178]

Answer:

-16

Step-by-step explanation:

The given linear function is ; f(x)=\frac{3}{4}x+12

Let y=\frac{3}{4}x+12.

We interchange x and y.

x=\frac{3}{4}y+12.

We solve for y.

x-12=\frac{3}{4}y.

We now multiply through by \frac{4}{3} to get:

\frac{4}{3}x-12\times\frac{4}{3}=y.

This simplifies to;

y=\frac{4}{3}x-16.

Hence f^{-1}(x)=\frac{4}{3}x-16.

The y-intercept is -16
