- 5+(-7)=5−7=-2
- 9+(-5)=9-5=4
- (-1)+9=−1+9=8
- 9+(-7)=9−7=2
- 50+(-7)=50−7=43
- 27+(-6)=27-6=21
- 1+(-30)=1-30=-29

Answer:
The answer is D
Step-by-step explanation:
Answer:
4.
Step-by-step explanation:
To find a function none of the x-values can be the same. For example, #1 isn't a function because 2 of the x values re 2 meaning it is not a function. #4 is a function because all of the x values are different numbers.
Rules in exponents:
<u>Let's review few rules before solving.</u>
- x⁰ = 1 (x can be any number)
- x⁻ⁿ (n ≠ 0 or any number below 0) = 1/xⁿ
Solution (9):
Solution (11):
- (-5)⁻²
- => 1/(-5)²
- => 1/-5 x -5
- => 1/25
Solution (15):
Solution (17):
Solution (26):
- k⁻⁴j⁰
- => k⁻⁴ x j⁰
- => k⁻⁴ x 1
- => k⁻⁴ = 1/k⁴
Solution (36):
- 7s⁰t⁻⁵/2⁻¹m²
- => 7 x s⁰ x t⁻⁵/2⁻¹ x m²
- => 7 x 1 x t⁻⁵ x 2/m²
- => 14 x t⁻⁵/m²
- => 14t⁻⁵m⁻²
Hoped this helped!
