Answer:
-10; no
Step-by-step explanation:
<h2>
-4*3 + 9*2 + 8*-2 = -10</h2><h2>
</h2><h2>
-10 does not equal 0 so it is not perpendicular</h2>
Answer:
C is the answer
Step-by-step explanation:
Garden dimensions:
y = width, 4y = length (because it says the length is four times the width)
equation:
y + y + 4y + 4y = 70
=> 10y = 70
=> y =70

Answer:
Correct answer is c.) 
Step-by-step explanation:
The vertex form of a parabola can be written as following:
is the co-ordinate of vertex.
is a constant whose positive or negative value decides where the parabola opens (up or down).
are the points on parabola.
and 
are interchangeable terms. We can use any of them.
For convenience with the co-ordinates in 
plane, is used here.
We are given that vertex is at (2,-1) and there is a point (5,8) on the curve.
i.e. h = 2 and k = -1,
x = 5 and y = 8
Putting the four values in equation (1):
Putting values of and in equation (1) to find the equation of parabola:
As told earlier as well, and are interchangeable terms.
So, correct equation of parabola is option C)

hope this helps
Answer:
Perimeter: 18 Area: Unknown
Step-by-step explanation: Add all the sides together, 2+4+4+8= 18
Area is length x width, and we do not know which numbers are the length or width.
