1. 72 to 50 points
50/72 = 69%
100-69= 31% decrease
2. 14 to 40 books
14 / 40 = 35%
100-35= 65% increase
3. 10 plus 30% increase
10 * 0.3 = 13
We will use the property :
sum of interior angles on same side of transversal =180
(8x-14) + (2x+54)=180
10x+40=180
10x=140
x=14

Answer:
f(2) = g(2) and f(0) = g(0)
Step-by-step explanation:
When x = x in f(x) and g(x), that means the two functions are equal.
The correct option is D. In fact, you can evaluate this function at every possible input x.
All this function does is:
- Take a number x
- Add 6
- If the result is negative switch the sign, otherwise keep it as it is
As you can see, you can perform these operations regardless of the input x.
