Answer:
5
Step-by-step explanation:
These are functions, the number in the parentheses shows you what number you will replace x with
If f(x) = x + 3, then f(-1) is -1 + 3
So, -1 + 3 = 2. g(2) = 2(2) + 1 = 4 + 1 = 5
Hope this helps friend.
Answer:
x > -17/2
Step-by-step explanation:
Step 1: Write inequality
-2x - 5 < 12
Step 2: Solve for <em>x</em>
<u>Add 5 to both sides:</u> -2x < 17
<u>Divide both sides by -2:</u> x > -17/2
Here, we can see that any number greater than -17/2 would work, so x could equal 01234718905731857013570 if we wanted it to, as long as it is greater than -8.5.
