Point (2,6) is 2/3 of the way from A to B. If A has coordinates (-8, 6), what are the coordinates of B?

Answers

Answer 1

The coordinates of the point B are (-5, 6)

How to determine the coordinates of the point B?

The given parameters are

A = (-8, 6)

Point = (2, 6)

Proportion = 2/3

Because the y coordinates are the same, we can make use of only the x coordinate

So, we have

Point = Proportion * (B - A)

This gives

2 = 2/3 * (B + 8)

Multiply through by 3/2

So, we have

3 = B + 8

Subtract 8 from both sides

B = -5

Hence, the coordinates of the point B are (-5, 6)

From the question, we are to find the y-intercept and x-intercept of the given line

The x-intercept of a line is the point where the line crosses the x-axis on a cartesian plane

The y-intercept of a line is the point where the line crosses the y-axis on a cartesian plane

From the graph, we can observe that the line only crosses the x-axis at the point (-3, 0). That is, at the point where x = -3

HELP

Answers

Using the vertical angles theorem, the value of x = 2.

How to Apply the Vertical Angles Theorem?

Given that angles A and B are vertical angles pair, based on the vertical angles theorem, both angles are congruent to each other.

Therefore:

m<A = m<B [vertical angles theorem]

m<A = (5x + 1)°

m<B = (4x + 3)°

Substitute

(5x + 1)° = (4x + 3)°

Solve for x

5x + 1 = 4x + 3

5x + 1 - 1 = 4x + 3 - 1

5x = 4x + 2

5x - 4x = 4x + 2 - 4x

x = 2

Therefore, using the vertical angles theorem, the value of x = 2.

The solution to the system of equations is (-7, 5)

What are linear equations?

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

How to determine the solution to the system?

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

2x + y = -9

3x + 5y = 4

Make y the subject in 2x + y = -9

So, we have

y = -2x - 9

Substitute y = -2x - 9 in 3x + 5y = 4

So, we have

3x + 5(-2x - 9) = 4

Open the bracket

So, we have

3x - 10x - 45 = 4

Evaluate the like terms

-7x = 49

Divide both sides by -7

x  = -7

Substitute x  = -7 in y = -2x - 9

y = -2(-7) - 9

y = 5

Answers

The probability that a student who can drive is a college student is 0.2771 or 27.7%

It will be sooved using Baye's theorem -

P(college) = P(C) / 1/5 = 0.2

P(high school students) = P(H) = 4/5 = 0.8

P(college drives) = 0.23

P(high school drives) = 0.15

We have to find, probability that a student who drives is a college student.

That is, we have to find P(C/D).

P(C/D) = P(C ∩ S)/P(S)

Since P(C ∩ S) is an independent event.

P(C ∩ S) = P(C) × P(S)

P(C ∩ S) = 0.2 × 0.23

= 0.046

Find the total amount given the original price and tax rate. round to the nearest hundredth if necessary. original price: $123.28 tax rate: 7.5% enter the correct answer in the box.

Answers

The Total amount to pay including the tax will be $132.52

In the given question, For the Total amount, we know that we have to add the Tax rate to the Principal amount. It is mentioned that the Principal amount P = $123.28 and the Tax rate is 7.5%. Firstly we have to calculate what amount of interest is to be charged upon the Principal amount. To calculate Interest we have the formula :

=>  I = (P * R)/100 , where I = Interest, P = Principal Amt, R = Interest Rate

=>  I = (123.28 * 7.5)/100   => I = 9.24

We get Interest amount = $9.24

To calculate the Total amount, We have the formula: T = P + I

where, T = Total Amount, P = Principal Amount, and I = Interest Amount

=>  T = 123.28 + 9.24  => T = 132.52

Hence, the Total Amount is $132.52

Statement a : "The standard deviation measures the variation of the data. If the standard deviation is 0, then there is some variation, so all the data are different" is false.

Statement b : "All the data must be equal to the mean because the sum of the squares of the differences of the data from the mean is 0. So, all the data take the same value" is true

What is standard deviation?

This is a term in statistics that represent the amount of variation in a data set or simply put the spread of the data set. Standard deviation is solved from the mean of the data, that is we get mean first before solving for standard deviation.

From the definition, if all the data is the same then the data should be equal to the mean. If the data is equal to the mean there will be no spread or variation leading to a zero standard deviation.

If m< EBC = 3y+10 and m< ABE = 2y-20, find m< EBF.

Answers

By using the fact that EBC and ABE are supplementary angles, we will see that the measure of angle EBF is 106 degrees.

How to find the measure of the angle EBF?

First, we can notice that angles EBC and ABE are supplementary angles, which means that their measures add up to 180°.

Then we can write:

m∠EBC + m∠ABE = 180°

Replacing what we know we get:

3y + 10 + 2y - 20 = 180°

Now we can solve this linear equation for y, we will get:

5y - 10 = 180

5y = 180 + 10

y = 190/5 = 38

Then we have that:

EBC = 3*38 + 10 = 124°

ABE = 2*38 - 20 = 56°

Now, in the image it says that:

ABE = 2b = 56°

then b = 56°/2 = 28°

And ABF = 7b - 24 = 162°

Then:

EBF = ABF - ABE = 162° - 56° = 106°

We conclude that the measure of angle EBF is 106 degrees.
