Final answer:

To find the coordinates of point C between points A and B given the ratio AC=1/4AB, determine the coordinates, with C being at (10.75, 7.5).

Explanation:

Coordinates of point A: A(8,6)

Coordinates of point B: B(-3,0)

Given AC = 1/4 AB, we can find the coordinates of point C by solving for the coordinates based on the ratio:

Calculate the difference in x-coordinates: 8 - (-3) = 11

Calculate the difference in y-coordinates: 6 - 0 = 6

Coordinates of point C: C(8 + 1/4*11, 6 + 1/4*6) = C(10.75, 7.5)

The question is about simplifying an algebraic expression, specifically 3x - 1/2y + 2 2/3y - 5/6x. This can be achieved by first consolidating like terms and performing multiplication and addition/subtraction to get the simplified expression 2 1/6x + 2 1/6y.

This question appears to be about simplifying algebraic expressions. The expression at hand is 3x-1/2y +2 2/3y -5/6x. To simplify this, you should first consolidate your like terms. The 'like terms' in this case, are the X terms (3x and -5/6x) and the Y terms (-1/2y and +2 2/3y).

Secondly, perform the operations necessary for the terms – which involve multiplication and addition/subtraction. Thus, the sum of 3x and -5/6x is 2 1/6x (or 2.167x if we want it in decimal form). Similarly, the sum of -1/2y and +2 2/3y is 2 1/6y (or 2.167y in decimal form).

Finally, to complete the simplification, you should combine these totals. The simplified algebraic expression for 3x - 1/2y + 2 2/3y - 5/6x is therefore 2 1/6x + 2 1/6y.

Answer:

Assuming each person gets the same amount of apples, each friend gets 3.6875lbs of apples.

Step-by-step explanation:

Now in order to find this, we need to note that 4 people get apples (Kenneth and 3 friends). So we take the total number of pounds and divide it by 4.

14.75lbs/ 4 people = 3.6875lbs per person

Hey there!!

The total number of people are '4 people

The weight is shared equally among all the 4 people.

The total weight is 14.75 pounds.

What is the weight of each person?

∴We know everyone has the equal weight.

... person + person + person + person = 14.75

... 4 × person = 14.75

... person = 14.75 / 4

... person = 3.68

Hence, the weight of apples each get is 3.68 pounds.

So if you let x and y be the two numbers...

the sum of the two means you add them together... so you get:

x+y=56 : the difference means you subtract them.. so

x-y = 16

now you have two equations and two unknowns... which you can solve with a variety of methods... you can use elimination, substitution, or trial and error.

x+y=56

x-y = 16

I will use the elimination method: Because there is a plus y and a negative you cancel that out and you add the 2x's. Therefore:

2x=72

x=36

Now, you can plug in 36 into one of your original equation:

36+y=56

y=20

Those are your two numbers!

The product of the numbers is 720.

Simplify fractions by cancelling all the common factors from both the numerator and the denominator and writing the fraction in its lowest/simplest form.

Given that, the sum of two numbers is 56. the difference of the 2 numbers is 16.

Let the numbers be x and y,

x+y = 56

x-y = 16

On solving, we get,

x = 36 and y = 20

x*y = 36*20 = 720

Hence, The product of the numbers is 720.

The probability that all seven arrows will not hit the bullseye is 1 2/5

Probability calculate how likely it is for an event to occur. The chances of an event occurring is between 0 and 1. The value of the event is one if the event happens and zero if the event does not happen.

For example the probability that it would rain everyday of the week lies between 0 and 1. If it rains, a value of 1 would be attached to the event and if it does not rain all the days of the week a value of zero would be attached to the event.

Probability all seven arrows does not hit the bullseye = number of arrows x probability of one arrow not hitting the bullseye

Probability that one arrow does not hit the bullseye = 1 - 4/5

5/5 - 4/5 = 1/5

Probability = 1/5 x 7 = 7/5 = 1 2/5

They wash a car for $5, so 5 represents the cost of washing one car. to find out how much they will earn by washing x cars, we can multiply 5 by any number to find the total cost of the washed cars. For example 5×2=10 which means the cost of washing 2 cars is $10 and 5×3=15 means the cost of washing 3 cars is $15 and also 5×4=20 means the cost of washing 4 cars is $20. Basically the cost of the washed cars will increase by $5 each time the number of cars increase.

If the point (a, b) is in Quadrant IV of a coordinate plane, then the x-coordinate of (a, b) will be positive and the y-coordinate will be negative.

EX: (5, -5)

Final answer:

The point (a,b) is in Quadrant IV, where 'a' is positive and 'b' is negative. Switching the coordinates to (b,a) places it in Quadrant II, where 'b' is now the x-coordinate (negative), and 'a' is the y-coordinate (positive).

Explanation:

Given that the point (a,b) is in Quadrant IV of a coordinate plane, where 'a' is the x-coordinate, and 'b' is the y-coordinate. In Quadrant IV, x-coordinates (a) are positive, and y-coordinates (b) are negative, hence a > 0 and b < 0. When we consider the point with coordinates (b,a), we switch the positions of 'a' and 'b'. Since 'a' is positive and 'b' is negative, the point (b,a) would then be in Quadrant II, where x-coordinates are negative and y-coordinates are positive. To recap, in the Cartesian coordinate system, a point's location is determined by the signs of its x and y values, which change across different quadrants, affecting the point's location accordingly.

Step 1: Line up the equations so that the variables are lined up vertically.

Step 2:  Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same.

Step 3:  Subtract the two equations.

Step 4:  Solve the one variable system.

Step 5:  Put that value back into either equation to find the other equation.

Step 6:  Reread the question and plug your answers back in to check.

Final answer:

To solve systems of equations, one can use methods like graphing, substitution, or elimination, and check the solution by substituting it back into the original equations. For inequalities, graph the lines, decide where to shade by testing a point, and find the overlap of the shaded regions for the solution.

Explanation:

Steps to Solving Systems of Equations and Inequalities

The process of solving systems of equations and inequalities involves several steps. To solve a system of equations, you can use methods such as graphing, substitution, or elimination. When solving inequalities, additional considerations such as shading the solution region are necessary. Here's a step-by-step approach for both equations and inequalities:

For Equations:

Choose a suitable method (graphing, substitution, elimination).

Apply the selected method to find the point of intersection, which represents the solution to the system.

Check your solution by substituting it back into the original equations.

For Inequalities:

Graph the lines or curves that represent the inequalities, using dashed or solid lines.

Determine where to shade the region by testing a point not on the line.

Find the overlap of the shaded regions if there is more than one inequality.

It's important to practice these steps with different systems to become proficient in solving them. Remember to pay close attention to the signs of the inequalities when graphing and shading the solution regions.

The n-th term for the sequence will be:  [tex]n^2+4n+2[/tex]

Step-by-step explanation:

Given sequence is:  7, 14, 23, 34, 47. 62, 79, ........

The n-th term of a quadratic sequence is:  [tex]t_{n}=an^2 +bn+c[/tex]

For [tex]n=1[/tex]....

[tex]t_{1}=a(1)^2+b(1)+c\\ \\ a+b+c=7 .............................(1)[/tex]

For [tex]n=2[/tex]....

[tex]t_{2}=a(2)^2+b(2)+c\\ \\ 4a+2b+c=14 .............................(2)[/tex]

For [tex]n=3[/tex]....

[tex]t_{3}=a(3)^2+b(3)+c\\ \\ 9a+3b+c=23 .............................(3)[/tex]

Subtracting equation (1) from equation (2), we will get......

[tex]3a+b=7..........................(4)[/tex]

Subtracting equation (2) from equation (3), we will get.......

[tex]5a+b=9..........................(5)[/tex]

Now, subtracting equation (4) from equation (5)...........

[tex]2a=2\\ \\ a=\frac{2}{2}=1[/tex]

Plugging this  [tex]a=1[/tex] into equation (4), we will get....

[tex]3(1)+b=7\\ \\ 3+b=7\\ \\ b=7-3=4[/tex]

Now, plugging [tex]a=1[/tex] and [tex]b=4[/tex] into equation (1) .........

[tex]1+4+c=7\\ \\ 5+c=7\\ \\ c=7-5=2[/tex]

Thus, the n-th term for the sequence will be:  [tex]n^2+4n+2[/tex]

To find the nth term of a quadratic sequence, we can follow these steps:

Step 1: Find the first difference.
To do this, we calculate the difference between the consecutive terms of the sequence.

14 - 7 = 7
23 - 14 = 9
34 - 23 = 11
47 - 34 = 13
62 - 47 = 15
79 - 62 = 17

Now we have the first difference sequence: 7, 9, 11, 13, 15, 17.

Step 2: Find the second difference.
If it's a quadratic sequence, the second difference should be constant. That is, the difference of the first difference sequence should be the same. Let's calculate it.

9 - 7 = 2
11 - 9 = 2
13 - 11 = 2
15 - 13 = 2
17 - 15 = 2

Great, our second difference is constant and equal to 2.

Step 3: Create the general quadratic formula.
Quadratic sequences are defined by the formula:
a_n = an^2 + bn + c

Since the second difference is constant and equal to 2, we know that 2a should be equal to the second difference. Therefore, a is half of the second difference.

a = 2/2 = 1
So our sequence has the form:
a_n = n^2 + bn + c

Step 4: Find b and c.
We use the given terms from the sequence to find the values of b and c. We know that the first term (when n=1) is 7.

a_1 = 1^2 + b(1) + c = 7
1 + b + c = 7
b + c = 6 ... [1]

We also know that the second term (when n=2) is 14.
a_2 = 2^2 + b(2) + c = 14
4 + 2b + c = 14
2b + c = 10 ... [2]

At this point, we have two equations with two variables. We can resolve this system of equations to find b and c.

Step 5: Solve the system of equations.
We can subtract equation [1] from equation [2] to find the value of b.

(2b + c) - (b + c) = 10 - 6
2b - b + c - c = 4
b = 4

Plug the value of b into either equation [1] or [2] to find c.

b + c = 6
4 + c = 6
c = 6 - 4
c = 2

Step 6: Write down the nth term formula with the found coefficients a, b, and c.
a_n = n^2 + 4n + 2

Therefore, the nth term of the quadratic sequence 7, 14, 23, 34, 47, 62, 79 is a_n = n^2 + 4n + 2.

A number is 2/3 of another number.  Both added together equals 50.

One of these numbers consists of three parts, and the other consists of two of those three parts.  So, there are 5 equal parts in total.

Thus we need to divide 50 by 5.  50 divided by 5 equals 10.

The first number, which has three parts, is 30.  The second number, which as two parts, is 20.

I hope this makes sense to you.  :D  Good luck in all your studies!

To find the numbers, we solve an equation by combining like terms and finding the value of x. The numbers are 30 and 20.

Let's call the first number x. The second number is 2/3 of x, so we can represent it as (2/3)x. The sum of the numbers is 50, so the equation becomes:

x + (2/3)x = 50

To solve for x, we can simplify the equation by finding a common denominator and combining like terms:

Now that we have the value of x, we can substitute it back into the equation to find the value of the second number:

(2/3)x = (2/3)(30) = 20

Therefore, the numbers are 30 and 20.
