Given the following functions, find and simplify (f • g)(x) f(x)=—x+3 g(x)=-x-1

Hitman42 [59]

Answer:

$(f\circ g)(x)= x + 4$

Step-by-step explanation:

<u>Composite Function</u>

Given f(x) and g(x) as real functions, the composite function $(f\circ g)(x)$ is defined as:

$(f\circ g)(x)=f(g(x))$

It can be found by substituting g into f.

We are given the functions:

f(x) = -x + 3

g(x) = -x -1

Find

$(f\circ g)(x)=f(g(x))= - (-x -1) + 3$

Removing parentheses:

$(f\circ g)(x)= x + 1 + 3$

Simplifying:

$\mathbf{(f\circ g)(x)= x + 4}$

Y varies directly with x, and y = 5 when x = 4. What is the value of x when y = 8?

Tomtit [17]

As y varies directly with x, there is a proportionality constant. As x increases by that certain constant, y also increases. We equate:
y = kx
where k = proportionality constant.
Given the condition, y = 5 when x = 4, then we solve for k:
5 = k(4)
k = 5/4 or 1.25
When y = 8, then
8 = (5/4)(x)
x = 8/(5/4) = (8)(4/5) = 32/5 or 6.4 (ANSWER)

There are four red ,four blue, and two green marbles in a bag .if one marble is chosen at random from the bag what is the probab

mina [271]

Answer:

There is a 20% probablity that the marble will be green :)

Step-by-step explanation:

There are a total of 10 marbles in the bag. 4 red+4 blue+ 2green=10
There are two green marbles out of the 10 marbles. 2/10
2 divided by 10 is .20 or 20%
Therefore, there is a 20% probability that the marble will be green.
