A slope field produces...
A. the graph of the general solution to the differential equation
B. the graph of the derivatives of the differential equation
Please explain. I am so confused on this.
It's A. B doesn't really make sense ("derivative of the differential equation" is somewhat nonsensical, "derivative of an equation" is not meaningful).
More to the point: Slope fields are used to visualize solutions to differential equations of the form
y' = f(x, y)
You take some point (x, y) and evaluate y' at the point. This gives the slope of the line tangent to the particular solution to the DE that passes through the point (x, y ).
Sample several points and evaluate y' at those points and you get several different slopes.
Simple example:
y' = x ² - y ² = (x + y ) (x - y )
Let's take the points (1, 1), (-1, 0), and (2, -2), at which we get slopes
y' = f (1, 1) = 0
y' = f (-1, 0) = 1
y' = f (2, -2) = 0
From here, you can get particular solutions that pass through a certain point by interpolating the slopes of the tangents to the solution. I've attached a slope field for the example here at the points listed above. (In the order red, green, black). Each light gray arrow in the background shows the slope of the tangent line.
If you're still unsure how the slope field is generated, I suggest looking up videos on the subject. The process is a bit difficult to describe without a dynamic visual aid.

Assuming that no denominator equals zero, which expression is equivalent to (n^2-7n+12)/(n-3)(n+4)
Answer:
D
Step-by-step explanation:
took the test
The expression is equivalent to (n² - 7n + 12) is (n-4)/ (n+4).
The correct option is D.
What is Expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:
Expression: (Math Operator, Number/Variable, Math Operator)
We have,
(n² - 7n + 12) / (n-3)(n+4)
So, Factorizing (n² - 7n + 12)
= (n² -3n - 4n +12)
= n(n-3)- 4(n-3)
= (n-3)(n-4)
Then, (n² - 7n + 12) / (n-3)(n+4)
= (n-3)(n-4)/ (n-3)(n+4)
= (n-4)/ (n+4)

Is (5,0) a solution of the graphed inequality?
Answer:
Yes
Step-by-step explanation:
5,0 is a solution to the graphed inequality as it lies on the edge of the shaded area. Because the line is solid rather than dotted/dashed this means that all answers on the line will be included in the solutions. This is a graph for an inequality with one of these symbols ≤ ≥.

Triangle X has m2A = 30°, mZB = 90°, and m2C = 60° with side lengths of AB = 3, BC = 4, AC = 5.
Triangle Y has m2A = 30°, mZB = 90°, and mZC = 60' with side lengths of AB = 9, BC = 12, AC = 15.
Which statement best describes the relationship between these two triangles?
O They are similar triangles.
O They are similar and congruent triangles.
O They are congruent triangles.
O They are congruent but not similar triangles.
Answer:
O They are similar triangles.
Step-by-step explanation:
Given
Triangle X
[tex]\angle A = 30[/tex]°, [tex]\angle B = 90[/tex]°, [tex]\angle C = 60[/tex]°
[tex]AB = 3,\ BC = 4,\ AC = 5.[/tex]
Triangle Y
[tex]\angle A = 30[/tex]°, [tex]\angle B = 90[/tex]°, [tex]\angle C = 60[/tex]°
[tex]AB = 9,\ BC = 12,\ AC = 15.[/tex]
Required
The relationship between X and Y
From the given parameters, the corresponding angles of both triangles are equal i.e.
A = A, B = B and C = C
However, the side lengths are not equal.
The side lengths of Y is 3 multiplied by the side lengths of X.
This is shown below:
Triangle X
[tex]AB = 3,\ BC = 4,\ AC = 5.[/tex]
Multiply by 2 to get Triangle Y
[tex]AB= 3 * 3 = 9[/tex]
[tex]BC= 4 * 3 = 12[/tex]
[tex]AC = 5 * 3 = 15[/tex]
Since side lengths are not equal, but they have a common ratio of 3, then the triangles are similar.

Answer:
90,45,45
Step-by-step explanation:
it a system of equations
say that x y and z are each angles of the triangle
that means that they add up to 180 so x+y+z=180
the question says that two of the angles in the triangle are equal so we can just say that x=y
and it says that the two angles that are the same length have a sum that is equal to the third side of the triangle which basically is x+y=z
x+y+z=180
x+y=z
x=y
we start with the first two equations:
since x+y=z then we can substitute z in for x+y in the first equation
z+z=180
2z=180
z=90
and since x=y then
x+x=z
2x=90
x=45
y=45
z=90
hope that helps :)

Point NN is located at (-2,-6)(−2,−6) on the coordinate plane. Point NN is reflected over the yy-axis to create point N'N ′ . Point N'N ′ is then reflected over the xx-axis to create point N''N ′′ . What ordered pair describes the location of N''?N ′′ ?
Given:
Coordinates of point N = (-2,-6)
Point N is reflected over the y-axis to create point N ′.
Point N' is then reflected over the x-axis to create point N''.
To find:
The ordered pair that describes the location of N''.
Solution:
The coordinates of point N are (-2,-6). Point N is reflected over the y-axis to create point N ′.
[tex](x,y)\to (-x,y)[/tex]
[tex]N(-2,-6)\to N'(2,-6)[/tex]
Point N' is then reflected over the x-axis to create point N''.
[tex](x,y)\to (x,-y)[/tex]
[tex]N'(2,-6)\to N''(2,6)[/tex]
Therefore, the ordered pair for point N'' is (2,6).
Answer:
(-6,2)

If I have an 86% overall grade in a class and score 40% on a test, what will my grade come out as?
Answer:
It really depends on how much percent of your overall grade tests count as. But, usually they count for about 60% of your grade (depending on what grade you are in). You have about 65% at the lowest and a 75% at the highest. But, I'm just going by what my school does, I don't know how your school grades tests.

Answer:
180° (in place of blank)
Step-by-step explanation:
GIVEN :-
∠D = 127°∠A = 75°PROCEDURE :-
∠C & ∠D are linear pair. (∵ They lie on same line)
⇒ ∠C + ∠D = 180°
⇒ ∠C = 180° - 127°
In a triangle , sum of its all interior angles equals to 180° (which is also known as "Angle Sum Property). So,
∠A + ∠B + ∠C = 180°
⇒ 75° + ∠B + (180° - 127°) = 180°
⇒ ∠B = 180° - 75° - (180° - 127°)
Answer:
180%

Write the equation of the line, in slope intercept form, that goes through the points (6,4) and (-3,-5)
Answer:
y = x - 2
Step-by-step explanation:
Find the slope using rise over run
(y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-5 - 4) / (-3 - 6)
-9 / -9
= 1
Using y = mx + b, plug in the slope and a point to solve for b:
y = mx + b
4 = 1(6) + b
4 = 6 + b
-2 = b
Plug in the slope and b to y = mx + b
y = 1x - 2
y = x - 2
So, the equation of the line is y = x - 2
