Step-by-step explanation:
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.

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)

A line passes through the point (-2, -7) and has a slope of5/2
Write an equation in slope-intercept form for this line.
Answer:
y=5/2x-2
Step-by-step explanation:
y-y1=m(x-x1)
y-(-7)=5/2(x-(-2))
y+7=5/2(x+2)
y=5/2x+10/2-7
y=5/2x+5-7
y=5/2x-2

Genny is making bracelets for her friends. She can make 3 bracelets in 15 minutes. How long will it take Genny to make a bracelet for all 10 of her friends?
Answer:
50 minutes
Step-by-step explanation:
15 / 3 = 5
5 x 10 = 50
Answer
50 minutes
Step-by-step explanation:
If Genny makes 3 bracelets in 15 minutes, she can make 9 bracelets in 45 minutes.
9/3 = 3
3 x 15 = 45 minutes
She needs to make one more bracelet. It takes 5 minutes to make one bracelet because: 15/3 = 5/1 (Five minutes = One bracelet)
45 mins + 5 mins = 50
Without multiplying circle whether each product is greater than, less than, Equal to the whole number
Step-by-step explanation:

Step-by-step explanation:
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

The new computer you want to buy costs $749.50. If you wait for it to go on sale for 17% off, what will the sale price be?
Answer:
$622.09
Step-by-step explanation:
The computer is $749.50 and if the computer is 17% off, it means that you only need to pay 83% of the original cost.
749.50/100 = 74.95
74.95*83 = $622.085
Since the thousandth is a 5, round up to $622.09
The sale price is $622.09

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = ( 82 - 42 ) ( 1/4 )²
On simplifying the equation , we get
A = ( 40 ) ( 1/16 )
A = 40/16
A = 2.5
Hence , the expression is solved and A = 2.5

PLEASE HELP ASAP! Determine whether each graph represents a direct variation relationship
Answer:
1. Yes, it does not have a y-intercept, but has slope.
2. No, it has y-intercept.
Step-by-step explanation:
A direct variation relationship has to be able to fill in the equation y=mx. Any direct variation relationship cannot have a y-intercept in it. Therefore, question 1 is a direct variation relationship and question 2 is not a direct variation relationship.

Solve 2x - 3 = 1 help please
Answer:
first add 3 to both sides to get rid of the three on the left side
2x = 4
then divide 2 from both sides since it is the opposite of the operation shown then you'll get x = 2 when dividing to on the left side you get rid of it because you are trying to get rid of as much of the numbers as possible.
Answer:
X=2
Step-by-step explanation:
1). cancel the -3 out on both sides of the equation
2). When you add together the 1 and 3, you will recieve the value of 4
3).In order to get the x attached to the coefficient 2 isolated you have to divide 2 on both sides
4.) 2x = 4
5). 2x/2 = x
6). 4/2 = 2
Therefore x=2
