First convert x^2 + 10x - 9 to vertex form and you will get
f(x) = (x-5)^2 - 34 This means that the vertex must be (5, 34)
Answer:

Step-by-step explanation:
Answer:
4800
Step-by-step explanation:
A day consist of 24 hours. Half of 24 is 12. 4 x 13 = 12 so 1600 x 3 = 4800.
Answer:
x = 16°, y = 116°
Step-by-step explanation:
Angles inside a U-shape add up to 180°.
Hence (6x + 20)° + (4x)° = 180°
10x = 160°
x = 16°
Since the slanted sides of the trapezium are equal, y is equal to (6x + 20).
(6x + 20)° = (6(16) + 20)° = 116° = y
