Answer:what do you mean
Step-by-step explanation:
Answer:
a. y = {x+1, x≤2; x+2, x>2}
Step-by-step explanation:
The open circle at (2, 4) means the function is not defined as y=x+2 at that point. Only one answer selection correctly uses the inequality symbol > for that part of the function definition.
___
Comment on the other answer choices.
One selection (b) uses the region definitions x < 2 and x ≥ 2. That would put the open circle at (2, 3) and the filled circle at (2, 4)—not a match with the graph. The other function definitions (c, and d) have the relation defined as two different values at x=2. Such a relation is not a function.
Answer:
20 degrees
Step-by-step explanation:
sum of interior angles:
180 = 70 + 70 + 2x
solve for x,
180 = 140 + 2x ---> 2x = 40 or. x = 20
![\frac{7}{20} + ( - \frac{3}{4} ) =](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B20%7D%20%20%2B%20%28%20-%20%20%5Cfrac%7B3%7D%7B4%7D%20%29%20%3D%20)
![\frac{7}{20} - \frac{3}{4} =](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B20%7D%20%20-%20%20%5Cfrac%7B3%7D%7B4%7D%20%20%3D%20)
7 x 1 = 7
5 x 3 = 15
20 x 1 = 20
![= \frac{7 - 15}{20}](https://tex.z-dn.net/?f=%20%20%3D%20%5Cfrac%7B7%20-%2015%7D%7B20%7D%20)
![= \frac{ - 8}{20}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B%20-%208%7D%7B20%7D%20)
![= - \frac{8}{20}](https://tex.z-dn.net/?f=%20%3D%20%20-%20%20%5Cfrac%7B8%7D%7B20%7D%20)
![= - \frac{2}{5}](https://tex.z-dn.net/?f=%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B5%7D%20)
So, the number that belongs in the green box is 2.
