The answer is 18. F(2) is saying that x is equal to 2. so where ever there is an x in the problem you should fill in 2 for. then all you have to do is type it into a graphing calculator and solve.
Answer:
{-8,28}
Step-by-step explanation:
|10-x|=18
The absolute value has two solutions, one positive and one negative.
10-x = 18 and 10-x = -18
Subtract 10 from each side
10-10-x = 18-10 10-10-x=-18-10
-x = 8 -x = -28
Multiply each side by -1
x = -8 x = 28
Here, scale factor = 1 : 20
On scale, Tree's height = 6 3/4 = 27/4
Height of Actual Tree = 27/4 * 20 = 27 * 5 = 135
In short, Your Answer would be 135
Hope this helps!
