ANSWER
The vertex is (-2,1)
EXPLANATION
We want to find the vertex of
We complete the square to obtain,
The first three terms forms a perfect square trinomial.
The vertex form is
This equation is in the form;
where (h,k)=(-2,1) is the vertex.
When 10 by anything you just write the amount of 0 so if it was 10^12 i would write 12 0s so 10^6 1,000,000
Answer:
C
Step-by-step explanation:
C. x=7, y=5
To compare fractions you need a common denominator, then you can make a
comparison. You would divide the number line between 0 and 1 (or any 2
whole numbers on the number line) based on that common denominator. For
example... if you were trying to compare 3/4 and 2/8, you would find
the common denominator (in this case 8) and convert the fractions...
3/4 = 6/8
2/8 stays as 2/8
Now
you would go to the number line between 0 and 1 and divide it into 8
equal pieces. 3/4 would go over the 6th division and 2/8 would go over
the second division.
That would give you a good visual that 2/8 < 3/4

0 2/8 3/4 1
D. {x | x E R} because its all real numbers
