What is the answer to 6+9y-18=-3
lara [203]
6 + 9y - 18 = -3   Combine like terms (6 and -18)
      9y - 12 = -3   Add 12 to both sides
             9y = 9    Divide both sides by 9
               y = 1

Setler79 [48]

Answer:

\Huge \boxed{3a+4}

Step-by-step explanation:

The function is given.

f(x)=3x+1

To find :  f(a+1)

The input for the function f(x) is (a + 1).

Replace x with (a + 1).

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

Expand brackets.

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

Simplifying.

f(a+1)=3a+4
