Answer:
C.
Step-by-step explanation:
Jennifer completed the square by adding 1. However, to keep both sides equal, she should have added 1 to both sides:
y + 1 = (x² + 2x + 1) + 7
Or, she should have added 1 and subtracted 1 from the same side.
y = (x² + 2x + 1) + 7 − 1
The correct vertex form of the equation is:
y = (x + 1)² + 6
Answer:
The set of Real numbers
Step-by-step explanation:
x² + 4 is a parabola with the lowest point on the y-axis is 4 and continues up
-x² + 4 is a parabola with the highest point on the y-axis is 4 and continues down.
The range is the distance traveled on the y- axis.
All real numbers.
Answer:
22
Step-by-step explanation:
the answer is 22
Step-by-step explanation:
That's the system of numbering in indian system it is like thousand lakh ten.lakh crores and in international it is thousand ten thousand and hundred thousand and million
This is an excellent practice for the solution of quadratic equations.
1*36=36 => (1,36)
2*18=36 => (2,18)
3*12=36 => (3,12)
4*9=36 => (4,9)
6*6=36 => (6,6)
9*4=36 => (9,4)
12*3=36 => (12,3)
18*2=36 => (18,2)
36*1=36 => (36,1)
We can see that the sum decreases until the two factors are close (or equal) and then increases again.
The pair of integers with a sum of 20 is therefore (2,18) or (18,2).
