Answer:

x = 3

x = -3 + √ 10

x = -3 - √ 10

Step-by-step explanation:

I used a calculator

** I'm not sure if the x's are multiplication symbols or they're variables. (I'm assuming they're variables).

If it's wrong, I'm sorry!!

Answer:

y = 45 / 2x + 50

Step-by-step explanation:

The best equation for the line of the best fit would be y = 45 / 2x + 50.

The slope would be 45 / 2 and the y-intercept would be ( 0 , 50 ).

I used the points, ( 0 , 50 ) and ( 4 , 140 ) to get the equation, slope, and the y-intercept.

I used those points because they were the most accurate ones that I know for now.

Also, remember the formula is, "y = mx + b."

Answer:

216mx meters

Step-by-step explanation:

m is in minutes so convert it in hours = 60m hrs

Speed is in metres per second, convert it in kilometers per hour= 18x/5

Now we’ve time and speed, put it in the formula

Distance = speed x time

= 18x/5 x 60m

= 216mx meters

Hope it helps

Answer:

2 x  − 6

Explanation:

"Six less than.." means "Subtract 6 from".

Do not confuse this with "Six less..." which means "Subtract from 6".

Confusing, I know.

We know that "Double a number" means  

2 x , where  x  is your mystery number.

Therefore, we have:

2 x  −  6 , which translates to "6 less than 2x" or "6 less than twice a number"

Answer:

24 tickets would cost about $55.92

Step-by-step explanation:

To solve this equation I decided to figure out how much one ticket cost. I divided 7 by 3 and got 2.333333 I rounded that to one ticket costing $2.33. I then multiplied 2.33 by 24. 24 x 2.33= 55.92.

The reason I multiplied 24 by 2.33 is because the cost of one ticket is $2.33 so if I wanted to buy 24 tickets, I would have to multiply in order to find out the total cost.

I hope that this answer helped :D

Answer:

24 tickets would cost $56

Step-by-step explanation:

You would Convert it to a decimal by dividing the numerator by  the denominator. 7/3*24=$56

3 tickets cost=$7

1 ticket cost= 7/3=$7/3

Answer:

He made $51.25

Step-by-step explanation:

550+65=615

12% of 615 is 51.25 so your answer is 51.25

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)

Notice that the xx-coordinate and the yy-coordinate change sign when LL is reflected over the xx-axis and then reflected over the yy-axis.

Step-by-step explanation:

1+1

2

This question is so hard

Any number times one equals itself, and any number multiplied by two equals itself plus itself, so 1*2=2 and 1*2=1+1. The transitive property of equality states that if x=y and y=z then x=z. Since both 1+1 and 2 are equal to 1*2, they must be equal to each other, so 1+1=2.

                                                  The answer is 2

Answer:

C. 13

Step-by-step explanation:

Apply pythagorean theorem.

Thus:

Diagonal AV = √(12² + 5²)

AV = √(144 + 25)

AV = √169

AV = 13 cm

Answer:

560

Step-by-step explanation:

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

The Rule: If you are multiplying by a value less than one, your product will decrease. If you are multiplying by 1, the product will be equal and if you are multiplying by a value greater than 1, the product will increase.

Answer:

Step-by-step explanation:

No. of questions answered correctly = 166

Total no. of questions = 200

Percentage of questions answered correctly = (166/200)*100 = 83%

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.

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
