Answer:

f(a + 1) = 3a + 4

Step-by-step explanation:

Given the function is:

f(x) = 3x + 1

To determine f(a + 1) we have to substitute (a + 1) in place of 'x'.

Therefore, we have:

f(a + 1) = 3(a + 1) + 1

          = 3a + 3 + 1

          = 3a + 4

['a' could be any real number.]

So, f(a + 1) = 3a + 4 is the answer.

Is 3x = x + 8 true?​
ANEK [815]

Answer:

So 3x = x +8 is your equation

We adjust the equation to isolate the x and we end up with 2x = 8

We have to isolate the x even more to turn it into x = 4.

So our final answer is x = 4
