subtract 10 from each side
22 minus 10 gives you 12
then you just divide by 2 to get y.
Answer:
you divide the nominator by the denominator
Step-by-step explanation:
For example:
10/15
so 10 divided by 15= .6666...
10/15 as a decimal is .6 repeating
Answer: Vertex (5 ,-9)
Step-by-step explanation:
Given : Function f(x) = (x – 8)(x – 2).
To find : What is the vertex of the quadratic function .
Solution : We have given that f(x) = (x – 8)(x – 2).
On removing parenthesis
f(x) = x²-2x -8x +16.
f(x) = x²-10x +16.
We need to find vertex of this function ,
Vertex: (h, k)
h = -.
Plugging values
h = -.
h = 5 this is the x- coordinate,
Now , we will plug x= 5 in quadratic function .
k = (5)²-10(5)+16.
k = 25-50 + 16
k= -9.
Vertex (5 ,-9)
Therefore, Vertex (5 ,-9).
Answer:
8:125
Step-by-step explanation:
The ratio of the lengths would be the scale factor
The ratio of the volumes is the scale factor cubed
2^3 : 5^3
8:125
