K = 3
To find K:
7 (9 + k) = 84
63 + 7k = 84
7k = 21
21 / 7
k = 3
Answer: (A) 59° 32' 20"
<u>Step-by-step explanation:</u>
90° - 30°27'40"
Borrow a degree from 90° to create 60 minutes.
Then borrow a minute from 60 minutes to create 60 seconds.
90° = 89° 59' 60"
<u>- 30° 27' 40"</u>
= 59° 32' 20"
Answer:

Y-intercept= 1
Step-by-step explanation:
X= 0,1
Y=1,0
Answer:
4
Step-by-step explanation:
The degree of the polynomial determines how many distinct roots it can have. With degree 4, the number is 4.
X² - 9 = 55
+ 9
x² = 64
√
x = ± 8
So your answer would be x = 8 or x = -8
I hope this helps!
