Answer:

x =  \frac{41}{2}

Step-by-step explanation:

x - 5 - 3x + 1 = -45

-2x - 4 = -45

-2x = -45 + 4

-2x = -41

x = 41 ÷ 2

x = 41/2

<u>Step 3: Find f[g(1)]</u>

  1. Substitute in g(1):                    f[g(1)] = 2(1) + 1
  2. Multiply:                                   f[g(1)] = 2 + 1
  3. Add:                                         f[g(1)] = 3

Please help me with the problem below! :)
Drupady [299]
First, lets subtract the goal by 3, because she already did them.

15 - 3
12

Now, lets divide by one because that will leave you with the number of days

12/1
12

So, It will take her 12 days if she keeps up with her goal.

Hope this helps!
