Answer:
49
Step-by-step explanation:
The given function is .
We expand to get:
We complete the square to obtain the vertex form as follows:
This function is now of the form:
, where (h,k)=(-4,49) is the vertex.
The y-value of the vertex is therefore 49

Answer:
x = 47°
Step-by-step explanation:
Since the two angles on a line add up to 180 degrees:
x = 180-133
x = 47°
so you want to get x to one side only.
3.4x-5=2.4x
add 5 to both sides
3.4x=2.4x+5
now get x to one side by subtracting 2.4x
so x=5
