After a 40% price reduction, an exercise machine sold for $564. What was the exercise machines prince before this reduction?

1 answer:

8 0

Let
x--------> the exercise machines prince before the reduction
y--------> the exercise machines prince after the reduction

we know that
y=$ $564$

 $y=x*[100-40]/100 \\ y=x*0.60 \\ x=y/0.60 \\ x=564/0.60 \\ x=940$

the answer is
$ $940$

Determine whether the function f(x) -1 / x^2 + x^4 is even odd or neither

kirill [66]

If f(-x) = f(x) then the function is even.

If f(-x) = -f(x) then the function is odd.

We have: $f(x)=\dfrac{-1}{x^2+x^4}$

calculate f(-x):

$f(-x)=\dfrac{-1}{(-x)^2+(-x)^4}=\dfrac{-1}{(-1x)^2+(-1x)^4}\\\\=\dfrac{-1}{(-1)^2x^2+(-1)^4x^4}=\dfrac{-1}{1x^2+1x^4}=\dfrac{-1}{x^2+x^4}=f(x)$

f(-x) = f(x), therefore your answer: The function f(x) is even.

If we have: $f(x)=\dfrac{-1}{x^2}+x^4$

$f(-x)=\dfrac{-1}{(-x)^2}+(-x)^4=\dfrac{-1}{x^2}+x^4$

f(-x) = f(x)

f(x) is even

What is the meaning of the variable x in terms of 2.25+0.5x=3.75?

Eddi Din [679]

You have to do 3.75-2.25=1.5 then 1.5/0.5 which means that x=3.
