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.
Answer:
14
Step-by-step explanation:
B is the midpoint of AC, in other words it is the halfway point.
So A to B should be equal to B to C
Our expression is:
2x + 9 = 37
Subtract 9
2x = 28
Divide by 2
x = 14
6x-42=4x
6x= 4x +42
2x= 42
x=21
16.2 because when you times 9 with 9 you get 81.
After that you divide 81 by 5 and you get 16.2
