Check the picture below.

The midpoint of AB is M(-4, -3). If the coordinates of A are (−1,−2), then B has coordinates of (-2, -7/3)

Midpoint, as the word suggests, means the point which lies in the middle of something. Midpoint of a line segment means a point which lies in the mid of the given line segment.

Line AB has a midpoint, M.

A is (-1, -2)

B is unknown, M is(−4,−3)

Let's assume straight line of the form y=mx+b, where m is the slope.

Rise = (-3-(-2))= -1

Run = (-4-(-1)) =  -3

Slope = (Rise/Run) = (1/3)

The line becomes y=(1/3)x+b

Calculate b, the y-intercept (the value of y when x is 0)

y=(1/3)x+b

-2 = (1/3)(-1)+b

b = -2 + (1/3)

b = -5/3

The equation becomes:

y=(1/3)x - -5/3

Find the value of y for x=-2:

y=(1/3)x - -5/3

y=(1/3)(-2) - 5/3

y= -7/3

The cost of one kg of mushroom is $2.90 while the cost of 1 kg of turnips is $1.10

An equation is an expression that shows the relationship between two or more numbers and variables.

A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.

Let x represent the cost of on kg of mushroom and y represent the cost of one kg of turnips.

The cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55. Hence:

2x + 2.5y = 8.55  (1)

The cost of 3 kg of mushrooms and 4 kg of turnips is £13.10. Hence:

3x + 4y = 13.10   (2)

From both equations:

x = 2.9, y = 1.1

Answer: 13

Step-by-step explanation:

According to the question, to write the solution for the logarithmic function, the concept of indices is also needed.

Therefore, the given expression is [tex]3 ln x+2 ln y = ln5[/tex]

The values get multiplied in addition. Therefore, the above expression can be written as: [tex]ln(x^{3} )+ln(y^{2} )+ln5[/tex]

Expression = [tex]ln(x^{3} )+ln(y^{2} )+ln5[/tex]

Using logarithmic definition, we can write:

[tex]ln(x^{3} )+ln(y^{2} )+ln5\\ln(5x^{3} y^{2} )[/tex]

The solution for the given expression is [tex]ln(5x^{3}y^{2} )[/tex]

If Jodi wants to visit her extended family in Barbados next summer, and the flight costs $450, then she needs to save 50$ each month if she wants to buy the flight in exactly 9 months.

If the flight costs $450, then the amount of money Jodi needs to save each month can be determined by using division.

Division is one of the four basic operations of arithmetic and involves the separation into equal parts.

By dividing the cost of the flight by the number of months, the money Jodi needs to save each month can be calculated.

Considering x to be money Jodi needs to save each month,

x = flight cost / number of months

x = 450 / 9

x = 50

Hence, the money Jodi needs to save each month if she wants to buy the flight in 9 months is calculated to 50$.

Step-by-step explanation:

first : the sum of all angles in a triangle is always 180°.

second : the law of sine

a/sin(A) = b/sin(B) = c/sin(C)

a, b, c are the sides, A, B, C are the the corresponding opposite angles.

therefore,

angle J = 180 - 71 - 46 = 63°

j/sin(J) = k/sin(K)

11/sin(63) = k/sin(46)

k = 11×sin(46)/sin(63) = 8.880673249... m

Function composition exists a mathematical procedure where two functions, f and g, exists taken and a function, h = g ⁰ f, exists produced such that h(x) = g(f(x)). The function g is used in this operation on the outcome of applying the function f to x.

Let the function be f(x) = 10x -10

We want to find (f ⁰ f⁻¹)(d)

To differentiate with respect to X, then we get

[tex]F^{-1}[/tex](x) = 10

To find the value of (f ⁰ f⁻¹)(d)

F([tex]f^{-1}[/tex](x)) = F(10)

F([tex]f^{-1}[/tex](x)) = 10x - 10

substituting the values in the above equation, then

F([tex]f^{-1}[/tex](x)) = 10(10) - 10

simplifying the above equation, we get

F([tex]f^{-1}[/tex](x)) = 100 -10

F([tex]f^{-1}[/tex](x)) = 99

Therefore, the value of (f ⁰ f⁻¹)(d) = 99

y = mx + b

In which:

For this problem, we have that:

Hence the cost functions are given as follows:

The costs are equal when:

A(x) = B(x)

3.75 + 4x = 2.5 + 4.5x

x = 1.25/0.5

x = 2.5.

Hence the cheaper costs are given as follows:

Alley B has the lower initial cost due to the lower cost for the pair of shoes.

For item b, if we increase the cost per game by $0.50 for alley A, we have that:

A(x) = 4.5x + 3.75.

we know that the total number of eggs is the same as the number of eggs in 30 boxes. Hence the ratio will be 2 : 30, and then divide both sides by 2 to get 1 : 15 as the ratio in its simplest terms.

The ratio of the number of eggs in three boxes to the total number of eggs is 1 : 10.

We have,

To find the ratio of the number of eggs in three boxes to the total number of eggs, first, let's calculate the number of eggs in three boxes:

Number of eggs in three boxes

= 3 boxes * 6 eggs per box

= 18 eggs

Now, the ratio of the number of eggs in three boxes to the total number of eggs is:

18 eggs : 30 boxes x 6 eggs per box

18 eggs : 180 eggs

Cancel out the common factors.

1 egg : 10 eggs

An extraneous solution is one that results from the process of addressing the problem but is not a legitimate solution to the problem, such as the answer to an equation.

A formula known as an equation uses the equals sign (=) to express how two expressions are equal.

Consider the equation,

[tex]4(3x-3)^{\frac{2}{3} } = 36[/tex]

Now, divide each side of the equation by 4.

[tex]\frac{4(3x-3)^{\frac{2}{3} }}{4}=\frac{36}{4}[/tex]

[tex](3x-3)^{\frac{2}{3} } = 9[/tex]

Cubing the above equation.

( 3x - 3 )² = 729

3x - 3 = ( √729 )

3x - 3 = ± 27

Now,

3x - 3 = 27

3x = 30

x = 10

and;

3x - 3 = - 27

3x = - 24

x = - 8

The equation of the inverse function of the function f(x) = x^2 - x - 2 is f'1(x) =  0.5 + √x + 2.25

Inverse functions are the opposite of an original equation. This means that for a function f(x), the inverse of the function f(x) is f-(x); it also represents the opposite function

The function f(x) is given as

f(x) = x^2 - x - 2

Start by expressing the above function in vertex form

Using a graphing calculator, we have

f(x) = (x - 0.5)^2 - 2.25

As a general rule, we start by writing f(x) as a variable (say f(x) = y).

So, the equation of the function becomes

y = (x - 0.5)^2 - 2.25

The next step is to switch/swap the positions of x and y in the above equation y = (x - 0.5)^2 - 2.25

The equation becomes

x = (y - 0.5)^2 - 2.25

Add 2.25 to both sides

So, we have

(y - 0.5)^2 = x + 2.25

Take the square root of both sides

y - 0.5 = √x + 2.25

Add 0.5 to both sides

So, we have

y = 0.5 + √x + 2.25

Express as an inverse function

f'1(x) =  0.5 + √x + 2.25

Hence, the inverse function of the function f(x) = x^2 - x - 2 is f'1(x) =  0.5 + √x + 2.25

On the second reduction, she reduced 25% of the original T-Shirt's price. She should have reduced the price of the T-Shirt after one reduction.

Step-by-step explanation:

The total number of seats in row g is 224.

Number of seats in a row a = 10

Number of seats in row b = 16

Number of seats in row c = 22

The common difference is d.

d = (22-16) = 6

The first term is a.

a = 10

The total number of rows is n.

n = 7

[tex]a _{n} = a + (n - 1)d[/tex]

[tex]a _{n} = 10 + (7 - 1)6[/tex]
