Determine the vertex by completing the square. Show process.
y = x2 -6x + 22
1 answer:
Answer:
(3,13)
Step-by-step explanation:

Note that by vertex form we have:

Where the vertex has the coordinates (h,k) so we change the sign of h and keep the same k value and so:
h=3 and k=13
Therefore the vertex of this parabola is: (3,13)

Answer:
25
Step-by-step explanation:
3x+2x+55=180
5x+55=180
5x=180-55
5x=125
X=125/5
X=25
So the value of X is 25
Answer:
X=1
Step-by-step explanation:
6x+12-3=15
6x+9=15
6x+9-9=15-9
6x=6
X=1
-4 because it is closer to the 0
Answer:

Step-by-step explanation:
the unit of length is meter,
so, 80cm=0.8cm, 10cm=0.1m
the length of the rail=
=
the function f(x) is increasing.
looking at the domain -2 < x < -1, we can see that the function f(x) = 2^x (labeled in blue) has an increasing slope.
