thx i will do the answer too!!!!!!!

Step-by-step explanation:

1. Direction Fields. Sketch the direction field for each of the following ordinary differential equations.

(a) dy

dx = x

2 − y

, (b) dy

dx =

2 − y

2 + y

, (c) dy

dx =

, (d) dy

dx = x − y

The coordinate plane below represents a town. Points A through F are farms in the town. graph of coordinate plane. Point A is at

We have that
A (-3,-4)
B (-4,3)
C (2,2)
D (1,-2)
E (5,-4)
using a graph tool
see the attached figure N 1

Part A: Using the graph above, create a system of inequalities that only contains points A and E in the overlapping shaded regions.

A (-3,-4) E (5,-4)
y<= -3
y>=-5
is a system of a inequalities that will only contain A and E
to graph it, I draw the constant y = -3 and y=-5 and and I shade the region between both lines
see the attached figure N 2

Part B: Explain how to verify that the points A and E are solutions to the system of inequalities created in Part A

we know that
the system of a inequalities is
y<= -3
y>=-5
the solution is all y real numbers belonging to the interval [-5,-3]

therefore
if points A and E are solutions both points must belong to the interval

points A and E have the same coordinate y=-4
and y=-4 is included in the interval

therefore
both points are solution

Part C: Chickens can only be raised in the area defined by y < −2x + 4. Explain how you can identify farms in which chickens can be raised

step 1
graph the inequality
y < −2x + 4
see the attached figure N 3
the farms in which chickens can be raised are the points A, B and D
are those that are included in the shaded part

How do i do these 2 problems please help

To plot points, you need to first look at the two axis ( The two lines with arrow heads). After looking you can see that there are numbers on each axis. To actually plot points, you will need to place them in this order (X,Y) these are called coordinates. What you need to do now, is simple. You just need to count! The boxes on the grid help with that. Place your finger right where the x and y axis meet. That point is 0. Trace your finger on the paper and move over the x line. When you see the point you need to figure out, stop when your finger is on the same grid line (your finger is on the lines making boxes vertically), be sure to keep in mind that the point does not have to be directly on the axis line, just make sure it’s on the same line going up. From that point, what you need to do is count backwards to that 0 point mentioned earlier. The number that you get is your first number, the y coordinate is the second point you need. To find that you apply the same formula, just going upwards instead of across. Stop moving your finger when you see a point on the same line. When you see it, count backwards again, and the number you get should be the y coordinate. If you still need additional help I have added a picture below which is close to your example. I hope this helps!
