The answer to this is Complementary Angles.
Answer:
x+y=11
Step-by-step explanation:
take the square root of both sides.
(x-7) + (y+3) = 7
collect like terms
x+y = 7+7-3
Answer: -842
Step-by-step explanation:
To find n95, we have to use the equation aₙ = d * n + a₁ - d
a₁ is the first term, which here is 4. d is the common difference, which we can find out but seeing what we can add pr subtract from 4 to -5 which also equals -5 to -14, in this equation, the common difference would be -9 as it goes down by 9 every term. Once we plug these into the equation, we get
a₉₅ = -9 * n + 4 - (-9)
We can solve this for - aₙ = -9n + 13
Now that we have our equation to find a term, we can plug in n for 95 for
-9(95) + 13
Which equals -842
