Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = -1x - 4
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-3) = -1(-3) - 4
- Multiply: f(-3) = 3 - 4
- Subtract: f(-3) = -1
9.9 because it's on the tenth place
Answer:
7x+3
Step-by-step explanation:
The only like terms are 5x and 2x
5+2=7
Let the number be 'x'
Since, the product of number and 4 less than twice that number is 336.
![x \times [(2 \times x) -4] = 336](https://tex.z-dn.net/?f=x%20%5Ctimes%20%5B%282%20%5Ctimes%20x%29%20-4%5D%20%3D%20336)
![x[2x -4] = 336](https://tex.z-dn.net/?f=x%5B2x%20-4%5D%20%3D%20336)


Now, we will split the middle term, we get



So, 
So, x = 14 or x = -12
Therefore, the negative number is '-12'.
