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: x = -2, y = 4
Step-by-step explanation:
Where the lines intersect on the graph.
X coordinate is x, Y coordinate is y.
Answer:
I'm almost positive it's .A but I'm not sure
Hey there! :D
Subtract 10 from 28.
28-10= 18
Now, divide that by 3. (for her three friends)
18/3= 6
Each friend got 6 erasers.
I hope this helps!
