Since we know it is between 80 and 99, the tens place can only either be 8 or 9.
If it is 8, the ones place is 5 since the digits must add to 13.
If it is 9, the ones place is 4 since, once again, the digits must add to 13.
Our options are 85 or 94. Based on the last clue, it is 85 since 8-5=3.
Final answer: 85
<u>Part 1: Finding </u>
Note that 
In this case, it is 
<u>Part 2: Domain</u>
For the domain, we need to make sure the radicand of h(x) is greater than or equal to 0, so we get 
Step-by-step explanation:
Commutative property of multiplication: Changing the order of factors does not change the product. For example, 4 \times 3 = 3 \times 44×3=3×44, times, 3, equals, 3, times, 4.
Associative property of multiplication: Changing the grouping of factors does not change the product. For example, (2 \times 3) \times 4 = 2 \times (3 \times 4)(2×3)×4=2×(3×4)left parenthesis, 2, times, 3, right parenthesis, times, 4, equals, 2, times, left parenthesis, 3, times, 4, right parenthesis.
Identity property of multiplication: The product of 111 and any number is that number. For example, 7 \times 1 = 77×1=77, times, 1, equals, 7.
any more help just ask:)
Answer:
−12≤p≤12
Step-by-step explanation:
Absolute value so the positive and negative of p.
p ≤ 12
-p≤12
divide by -1 (switch sign)
p≥- 12
P is greater than or equal to -12 but less than or equal to 12:
−12≤p≤12
