Yes because the perimeter of the bulletin is 23 feet. this is because to find perimeter you use 2(L)+2(W).
Answer: The slope is -2.
Step-by-step explanation:
(2,-3)
(-2,5)
Using the two given points, you can find the slope by finding the difference in the y coordinates and diving it by the difference in the x coordinates.
y coordinates: -3 - 5= -8
x coordinates; 2-(-2) = 4
Slope: -8/ 4 = -2
The saying "A picture is worth a thousand words" comes to mind here. You can list all of the possible points in a solution region, or you can list a few points to give the general pattern. Though this method requires a bit more work than simply graphing and showing the solution shaded region. A visual is often more efficient at conveying a message especially to those who aren't proficient with algebra. I'm sure there are other reasons why graphs are the better choice, but that's all I could think of really.
Answer:
y=-2x+11
Step-by-step explanation:
A parabola with an equation, y2 = 4ax has its vertex at the origin and opens to the right.
It's not just the '4' that is important, it's '4a' that matters.
This type of parabola has a directrix at x = -a, and a focus at (a, 0). By writing the equation as it is, the position of the directrix and focus are readily identifiable.
For example, y2 = 2.4x doesn't say a great deal. Re-writing the equation of the parabola as y2 = 4*(0.6)x tells us immediately that the directrix is at x = -0.6 and the focus is at (0.6, 0)
