Answer:
x=-1
Step-by-step explanation:
The axis of symmetry is along the vertex
The vertex is at (-1,-2)
The x coordinate is -1
x=-1
Answer: z < 4
z+4 > 2z
z+4-z > 2z-z ..... Subtract z from both sides
4 > z
z < 4
So the solution set for z is any number that is less than 4, which could be something like z = 2 or z = 3.
Don’t know ...............................
I think 6 because it’s a ratio
Because the yellow would always be twice as much as the red so 3x2 is 6 just like 6x2=12
The rule to convert a mixed fraction to an improper fraction is

Here in 
Here a = 422, b = 8 and c = 100
Now a × c = 422 × 100 = 42200
And 42200 + 8 = 42208
So we have

This fraction can also be reduced as

Hence
