Answer:
22
Step-by-step explanation:
The problem can be solved geometrically. By this way, the solution is going to be easy, as well.
We can see from the attached graph that the coordinates are the vertexes.
Considering a unit distance, we can find that the width of this rectangle is:
4 = 12 - 8
and the length is:
7 = 6-(-1)
Then, the perimeter is P = (4+7)*2 = 22
1. The coefficient of x is the constant of variation. It is 40.
2. -12 = -2*6 . . . . . you know this because you know your times tables
.. f(x) = -2x
Answer:
Solve the resulting equation for x
Quadrant I is top right
Quadrant II is Top Left
Quadrant III is Bottom Left
Quadrant IV is Bottom right.
This is how I like to think of it.
(x, y)
I = (+, +)
II = (-, +)
III = (-, -)
IV = (+, -)
So the answer would be either Quadrant 3 or 4 (Bottom Right or bottom left)
I hope this helps you!
