Answer:

Substitute the values given for f(x) and g(x), in 1. they say f(x)=4x and g(x)=1-x

and basically just substitute them for the functions themselves.

4x+1-x

add like terms!

4x-x = 3x!

3x+1 is your simplified answer, since it is an expression it cannot be simplified any further.

Given triangle ABC with sides AB = 3x + 4 , BC = 2x + 5 , and AC = 4x , determine the values of x such that triangle ABC exists

Jlenok [28]

Answer:

x > 1/5

Step-by-step explanation:

All of these three triangle inequalities must be satisfied:

AB +BC > AC

BC +CA > BA

CA +AB > CB

___

Taking these one at a time, we have ...

AB +BC > AC

3x +4 + 2x +5 > 4x

x +9 > 0 . . . . . subtract 4x

x > -9

BC +CA > BA

2x +5 + 4x > 3x +4

3x > -1 . . . . . . subtract 3x+5

x > -1/3 . . . . . divide by 3

CA + AB > CB

4x + 3x +4 > 2x +5

5x > 1 . . . . . . subtract 2x+4

x > 1/5

___

The only values of x that satisfy all of these inequalities are those such that ...

x > 1/5

If f(x) = x^4-x^3+x^2 and g(x)= -x^2, where x does not = 0, what is (f/g)(x)?

Korvikt [17]

For this case we have the following functions:

$f (x) = x ^ 4-x ^ 3 x ^ 2\\g (x) = - x ^ 2$

By definition of composition of functions we have to: $(f \ g) (x) = \frac {f (x)} {g (x)}$

So:

$\frac {f (x)} {g (x)} = \frac {x ^ 4-x ^ 3 x ^ 2} {- x ^ 2} = \frac {x ^ 4} {- x ^ 2} +\frac {-x ^ 3} {- x ^ 2}+ \frac {x ^ 2} {- x ^ 2} =$

By definition of division of powers of the same base we have to place the same base and subtract the exponents:

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

ANswer:

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