I think the answer may be C
Answer:
Please let me know if your quadratic is 
.
And if so your vertex is (-2,2) and your y-intercept is (0,-6)
Step-by-step explanation:
It says vertex so I'm thinking you meant . Please correct me if I'm wrong.
The vertex form of a quadratic is 
. It is called that because it tells you the vertex (h,k).
So if you compare the two forms you should see -h=2 while k=2.
-h=2 implies h=-2.
So the vertex is (h,k)=(-2,2).
To find the y-intercept, set x=0 and find y.
So the y-intercept is (0,-6).
Answer:

Hope this helps! I figured it out on a calculator. :)
Answer:
Step-by-step explanation:
Set up the slope formula to solve for the unknown:
which simplifies to
which simplifies a bit more to
Multiply both sides by -3 to get rid of the fraction, leaving you with:
6 - s = 15 and
-s = 9 so
s = -9
Answer:
The upper bound for the perimeter of the rectangle = 427.76 cm
Step-by-step explanation:
To obtain the upper bound for the perimeter, we need to first obtain the upper bound for the Length and Breadth of the rectangle.
Since, these dimensions were rounded to the nearest 1 decimal place, we can write down their ranges
Length = 127.3 cm
Width = 86.5 cm
Length can range from 127.25 cm to 127.34 cm
Breadth can range from 86.45 cm to 86.54 cm
The upper bound for the Length and Breadth of the rectangle are this 127.34 cm and 86.54 cm respectively.
Perimeter = 2 (L + B)
Upper bound of the perimeter
= 2 × (127.34 + 86.54)
= 2 × 213.88
= 427.76 cm
Hope this Helps!!!
