The value of the expression for the given values of a and b is -1

<h3>Evaluating an expression</h3>

From the question, we are to evaluate the given expression for the given values of a, b, and c

The given expression is

a + b

The given values are

a = 4,

b = -5,

and

c = -8

To evaluate the given expression for the given values of a and b, we will put the values of a and b into the expression,

That is,

a + b becomes

4 + -5

= 4 -5

= -1

Hence, the value of the expression for the given values of a and b is -1

A. Use composition to prove whether or not the functions are inverses of each other. B. Express the domain of the compositions u
Kryger [21]

Given: f(x) = \frac{1}{x-2}

           g(x) = \frac{2x+1}{x}

A.)Consider

f(g(x))= f(\frac{2x+1}{x} )

f(\frac{2x+1}{x} )=\frac{1}{(\frac{2x+1}{x})-2}

f(\frac{2x+1}{x} )=\frac{1}{\frac{2x+1-2x}{x}}

f(\frac{2x+1}{x} )=\frac{x}{1}

f(\frac{2x+1}{x} )=1

Also,

g(f(x))= g(\frac{1}{x-2} )

g(\frac{1}{x-2} )= \frac{2(\frac{1}{x-2}) +1 }{\frac{1}{x-2}}

g(\frac{1}{x-2} )= \frac{\frac{2+x-2}{x-2} }{\frac{1}{x-2}}

g(\frac{1}{x-2} )= \frac{x }{1}

g(\frac{1}{x-2} )= x


Since, f(g(x))=g(f(x))=x

Therefore, both functions are inverses of each other.


B.

For the Composition function f(g(x)) = f(\frac{2x+1}{x} )=x

Since, the function f(g(x)) is not defined for x=0.

Therefore, the domain is (-\infty,0)\cup(0,\infty)


For the Composition function g(f(x)) =g(\frac{1}{x-2} )=x

Since, the function g(f(x)) is not defined for x=2.

Therefore, the domain is (-\infty,2)\cup(2,\infty)

Dmitriy789 [7]
I'm assuming the first time you said "July" you meant June. If he continues his rate of 1.10 every day in the month of July he will have a total of 110.00. That would be 55+55.

strojnjashka [21]

Answer:

Q1) D

Q2) C

Step-by-step explanation:

Q1)

y ∝ x

y = kx

Let x=-1,y=2

2 = k(-1)

k = -2

Q2)

directly (y=kx)

Let x=2,y=4

4 = k(2)

k = 2

y = 2x

inverse (y = k/x)

Let x=2,y = 4

4 = k/2

k = 8

xy = 8
