Answer:
The vertex form is: y = 3(x-2)^2 + 7
. The vertex is (2, 7)
Step-by-step explanation:
Write the function: y = 3x^2 - 12x + 11 in vertex form
The vertex form of a quadratic equation is:
y = m(x - a)^2 + b where (a,b) is the vertex
For y = 3x^2 - 12x + 11
Solve for m
y = 3(x^2 - 4x) + 11
Complete the Square:
y = 3(x^2 - 4x + 4) + 11 - 4
y = 3(x - 2)^2 + 7
The vertex then is (2, 7)
Answer:
The answer is correct x =6.8, if she made an error, it might have been the steps she took.
Step-by-step explanation:
5.4 + x = 12.2
subtract 5.4 from both sides to put x terms on the left hand side, numerical number terms on the right hand side
5.4 - 5.4 + x = 12.2 - 5.4
x = 6.8
Answer:
B. 8 x 10^3
Step-by-step explanation:
1.6 x 10^5 / 0.2 x 10^2
= 160 000 / 20
= 8 000
You can write this as 8 x 10^3
2+ n

Answer:
Step-by-step explanation:
To know if a mutation has occurred, compare DNA base sequences with members of the species. To identify a chromosomal mutation, you could examine some karyotypes.
