Answer:
B. y=1/2x-5
Step-by-step explanation:
From the graph, we read the slope of line JK.
slope = rise/run = -3/-6 = 1/2
The equation we need has the same slope.
y = mx + b
y = (1/2)x + b
It passes through point P(6, -2). Now we find b.
-2 = (1/2)(6) + b
-2 = 3 + b
b = -5
The equation is
y = (1/2)x - 5
Complementary angles are angle pairs whose measures sum to one right angle (14 turn,90°, or π2 radians)
1 : 100,000
Because there are 100cm in a m and 1000m in a km
100 x 1000 = 100,000
Seven add five is 12 . A clock has four quarters , the first quarter is fifteen minutes.
Therefore, 5 1/5 hours after 7:00 = 12:15
We are given
arithmetic sequence: u(1)= 124, u(2)= 117, u(3)= 110, u(4)=103
so, first term is 124
u(1)= 124
now, we can find common difference
![d=u(2)-u(1)](https://tex.z-dn.net/?f=%20d%3Du%282%29-u%281%29%20)
![d=117-124](https://tex.z-dn.net/?f=%20d%3D117-124%20)
![d=-7](https://tex.z-dn.net/?f=%20d%3D-7%20)
now, we can find kth term
![u(k)=u(1)+(k-1)d](https://tex.z-dn.net/?f=%20u%28k%29%3Du%281%29%2B%28k-1%29d%20)
now, we can plug values
and we get
![u(k)=124+(k-1)*-7](https://tex.z-dn.net/?f=%20u%28k%29%3D124%2B%28k-1%29%2A-7%20)
![u(k)=124-7k+7](https://tex.z-dn.net/?f=%20u%28k%29%3D124-7k%2B7%20)
![u(k)=131-7k](https://tex.z-dn.net/?f=%20u%28k%29%3D131-7k%20)
u(k) must be negative
so,
![u(k)=131-7k](https://tex.z-dn.net/?f=%20u%28k%29%3D131-7k%3C0%20)
![131-7k](https://tex.z-dn.net/?f=%20131-7k%3C0%20)
now, we can solve for k
![7k>131](https://tex.z-dn.net/?f=%207k%3E131%20)
![k>18.714](https://tex.z-dn.net/?f=%20k%3E18.714%20)
so, it's closest integer value is
