Answer:
(-2, -4)
Step-by-step explanation:
You can complete the square of the equation to get
y+(4/2)^2 = x^2+4x+(4/2)^2
y+4 = x^2 + 4x + 4
y+4 = (x+2)^2
y = (x+2)^2 - 4
This gives the form y = a(x-h)^2 + k where (h, k) is the vertex of the equation. You can also arrive at the same conclusion by making some observations of the equation. (x+2)^2 minimum value is going to be 0 since and negative values resulting from x+2 is going to become positive because of the square. So the minimum value is when x+2 is 0 or when x is equal to -2 and when it's at that minimum value of 0 it's going to have 4 subtracted from it which gives the vertex of (-2, -4)

Answer:
Answer Undefined
Step-by-step explanation:
This line is a vertical line because the x coordinate is the same on both points (5 is the x coordinate in both points). Vertical line's slopes are undefined because they go from up to down.
Answer:
he is faster than 95% of his team
Step-by-step explanation:
To finde this
First: Add Miguel to his 19 people equals 20 people
Next divide the 19/20
Providing the answer 0.95
to get the percentage multiply the decimal by 100: 0.95*100
= 95%
Answer:
x = 30
Step-by-step explanation:
a) The sum of the angles along the line is 180°. That means ...
2x° +90° +x° = 180°
__
b) Subtracting 90° and dividing by 3° gives ...
3x° = 90°
x = 30
