The answer is B. 2x-y=0, because parallel lines have the same slope (2x), and when you substitute 0 for Y, you get 0 for X-- the origin, (0,0)
Answer: -1/9 which is <u>choice B</u>
Explanation:
The term "zeros" refers to the x intercepts.
Plug in y = 0 and solve for x.
y = -9x-1
0 = -9x - 1
9x = -1
x = -1/9
Answer:
≈13degrees
Step-by-step explanation:
It is given that Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. Then,
Using the formula, 
where s is the distance between the two cities and r is the radius of the earth,thus substituting the values, we get
⇒
Therefore, 
⇒
⇒
Thus, the latitude of B is=12.53 degrees≈13degrees
4 : 28 is the same as 4/28
4/28 = 1/7
The answer is C
In a triangle, the three interior angles always add to 180°
x + 3x + 5x = 180
9x = 180
x = 180/9
x = 20
<span>the smallest angle = x = 20</span>°
