Evaluate-a-function f(x) = f(7) =

Step-by-step explanation:

Hey there!

f(x) = 7/x

~ Simply keep the "7" in the place where "x" is there.

Therefore, X= 1.

Hope it helps....

After evaluating the function by putting x = 7, we get f(7)= 1

Step-by-step explanation:

We need to evaluate the function and find f(7)

For finding f(7) we will put x = 7 in the given function

So, putting x= 7 and finding f(7)

So, after evaluating the function by putting x = 7, we get f(7)= 1

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
