Rs = 8y + 4 , ST = 4y + 8 , and RT = 36 , find the value of y

1 answer:

4 0

I assume that you meant RS and ST are segments of RT. If that is true then:

RS+ST=RT, using the values for these given...

8y+4+4y+8=36 combine like terms on left side

12y+12=36 subtract 12 from both sides

12y=24 divide both sides by 12

y=2

Which statement best describes how to determine whether f(x) = 9- 4x4 is an odd function?

vitfil [10]

Answer:

Option C.

Step-by-step explanation:

Note: In the given function the power of x should be 2 instead of 4, otherwise all options are incorrect.

Consider the given function is

$f(x)=9-4x^2$

If $f(-x)=f(x)$ , then $f(x)$ is an even function.

If $f(-x)=-f(x)$ , then $f(x)$ is an odd function.

Now, substitute x=-x in the given function.

$f(-x)=9-4(-x)^2$

$f(-x)=9-4(x)^2$

$f(-x)=f(x)$

So, the given function not an odd function. It means it is an even function.

To check whether the given function is odd, we have to determine whether $9-4(-x)^2$ is equivalent to $-(9-4(x)^2)$ .

Therefore, the correct option is C.
