**Answer:**

2x + 8 = 12

x = 2

4x = 2 = 10

**Step-by-step explanation:**

**Answer:**

**x = 19**

**Step-by-step explanation:**

**Question: find x such that f(x) = 2/3**

**Given f(x) = (-1/3) x + 7**

**equate the value of f(x) to be 2/3**

**hence,**

**(2/3) = (-1/3)x + 7 (multiply both sides by 3)**

**(3) (2/3) = (3) (-1/3)x + (3) 7**

**2 = -x + 21**

**x = 21 - 2**

**x = 19**

Answer:

AFM = 140

LFM = 70

Step-by-step explanation:

Here, we are to calculate LFM and AFM

Since AFM was bisected, then LFM + AFL is AFM

and also AFL = LFM

Thus;

11x + 4 = 12x -2

12x-11x = 4 + 2

x = 6

AFM = AFL + LFM = 11x + 4 + 12x-2 = 23x + 2

Substitute x = 6

AFM = 23(6) + 2 = 140

LFM = 11x + 4 = 11(6) + 4 = 66 + 4 = 70

Assuming the other is equal to x, this would be a 30-60-90 triangle. This is because those angles must add to 90 degrees and one must be 2 times the second.
