Point of Y intercept is (0,4)
Y1-Y2=m(X1-X2)
Plug in x,y into X2, Y2 m=slope

y-4=2(x-0)
y-4=2x
y=2x+4
Table
Plug in for x and y

Suppose we want to choose colors, without replacement, from the colors red, blue, green, and purple.

DerKrebs [107]

The number of ways when the choice is not relevant is 4

<h3>How to determine the number of ways?</h3>

The number of colors are:

Colors, n = 4

The color to choose are:

r = 3

<u>Relevant choice</u>

When the choice is relevant, we have:

$Ways = ^nP_r$

This gives

$Ways = ^4P_3$

Evaluate

Ways = 24

Hence, the number of ways when the choice is relevant is 24

<u>Not relevant choice</u>

When the choice is not relevant, we have:

$Ways = ^nC_r$

This gives

$Ways = ^4C_3$

Evaluate

Ways = 4

Hence, the number of ways when the choice is not relevant is 4

F (x) =2x -4; find f (-4)

NemiM [27]

Answer:

f(-4) = -12

Step-by-step explanation:

$f(x)=2x-4$

To calculate f(-4), we need to substitute x in our equation above with -4:

$f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12$

Note that 2*(-4) = -8

Answer: f(-4) = -12
