1/2 (4-k)=2/5 distribute and find lcm

Step-by-step explanation:

I find it convenient to do the problem in the reverse order: find the LCM, then distribute. That way, I'm not distributing a fraction.

The LCM of 2 and 5 is their product: 2·5 = 10. Multiplying the equation by 10 gives ...

  5(4 -k) = 4

Now, distributing, we get ...

  20 -5k = 4

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
