Answer:
1269
Step-by-step explanation:
convert and add
There are 3 outcomes in each game.
For 1st game, there can be either win (W), lose(L) or Tie (T).
For each of these outcome, there can be 3 possible outcomes in 2nd game i.e. either W, L or T
So, the tree diagram will have 3 branches, each further dividing into 3 more branches(nodes)
Thus option C gives the correct tree diagram.
Answer:
1. Add 5 to both sides
2. Divide both sides by 2
3. Take the square root of both sides
4. Subtract 2 from both sides
Step-by-step explanation:
2(x+2)²-5=93
<em>Add 5 to both sides</em>
2(x+2)²=98
<em>Divide both sides by 2</em>
(x+2)²=49
<em>Square root both sides</em>
x+2=7
<em>Subtract 2 from both sides</em>
x=5
4)
x + 5 < 14
Subtract 5 on both sides
x + 5 - 5 < 14 - 5
x < 14 - 5
x < 9
Answer is D.
5)
< (less than) and > (greater than) have empty circles because the number is not included.
For example, x > 5
5 is not a solution because we are looking for all x that is greater than 5.
≤ (less than or equal to) and ≥ (greater than or equal to) have a closed circle because the number is included.
For example, x ≤ 7
7 is a solution because we are looking for all x that is less than or equal to 7.
Answer is C.
6)
4(x-1) ≥ 8
Divide 4 on both sides
(x-1) ≥ 2
Add 1 on both sides
x ≥ 3
Answer is D.
The answer is D
This is because those are the ones that are x and y titles
