The symbol means "plus minus".
Writing is the same as saying
The lower bound, or left endpoint, is 1.5 - 0.85 = 0.65
The upper bound, or right endpoint, is 1.5 + 0.85 = 2.35
Based on what you have, it looks like you probably followed those steps. However, you have the items in the wrong order. You should have 0.65 listed first and 2.35 listed last. Also, you need to have "or equal to" as part of the inequality sign.
So you should have
As for your graph, you have the endpoints in the wrong spot.
The left endpoint should be between the 0.6 and 0.7 to indicate 0.65
The right endpoint should be between 2.3 and 2.4 to indicate 2.35
See the diagram below.
Answer:
Step-by-step explanation:
Jack's method is equivalent because of the "law of commutative property", which means that multiplication problems have the same result no matter the order.
2x5 is the same as 5x2
Answer:
+-2
Step-by-step explanation:
Answer: x=6 and the angle is 50
Step-by-step explanation:
1. a whole triangle = 180°
2. subtract 70 and 60 to get 50
3. subtract 2 from 50 and get 48
4. divide 48 by 8 and you get 6.
hope this helps :) everyone reading this have a great day!
5 squared +12 squared= 13squared 25+144=169
10 + 24 /=/ 28 one common ratio is 5 12 13 this does not match up
15+36= 39 5 12 13 ratio
50 120 and 130 5 12 13 ratio
