3x + 2x = 5x
-3 - 8 = -11
5x - 11 = 0
5x - 11 (+11) = 0 (+11)
5x = 11
5x/5 = 11/5
x = 11/5
hope this helps
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
Answer:
(- 5, - 28 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² + 10x
f(x) = x² + 2(5)x + 25 - 25 - 3
= (x + 5)² - 28 ← in vertex form
with (h, k) = (- 5, - 28)
Vertex = (- 5, - 28 )
