6.4x + 3y = 36

x = 3

6.4(3) + 3y = 36

6.4 * 3 = 19.2

19.2 + 3y = 36

36 - 19.2 = 16.8

19.2 - 19.2 = 0

3y = 16.8

16.8/3 = 5.6

3y/3 = y

y = 5.6

Consider the function attached below

Masja [62]

Answer:

Step-by-step explanation:

Hello,

$x=(fof^{-1})(x)=f(f^{-1}(x))=\sqrt{2f^{-1}(x)}+5\\\sqrt{2f^{-1}(x)} =x-5\\2f^{-1}(x)=(x-5)^2\\f^{-1}(x)=\dfrac{(x-5)^2}{2}$

now let's replace x by 7 it comes

$f^{-1}(7)=\dfrac{(7-5)^2}{2}=\dfrac{2^2}{2}=2$

hope this helps
