Answer:

y=12

Step-by-step explanation:

Solve the equation to get the value of y:

Simplify both sides:

\frac{3}{6} +\frac{2}{4} =\frac{y}{12}

\frac{1}{2} +\frac{1}{2} =\frac{1}{12} y

(\frac{1}{2}+\frac{1}{2}  )=\frac{1}{12}y

1=\frac{1}{12} y

Now flip the equation:

\frac{1}{12} y=1

Multiply both sides by 12:

12*(\frac{1}{12}y )=(12)*(1)

y=12

Therefore, y = 12

Answer:

1.  144  2. 16 3. 1   4. 3x-6  

Step-by-step explanation:

So think of this as a function in a function.  So you work from the inside to the outside.  So for problem 1, we start with f(4)) [you read it "f of 4"] so what is the solution when x = 4, since f(x) means the function of x so f(4) means 'the function of 4' inside f(x).  

Since f(x) = 3x then f(4) = 3(4) [notice how you substitute the 4 everywhere you see a letter x]

so f(4) = 12, now you work the next part h(f(4)) since f(4)=12 then h(12)

So take the h(x) function which is h(x) = x^{2} then h(12) = 12^{2} so h(12) = 144
