Money received in tenth month: $104, as found by the formula of arithmetic progression.

The formula used here is recursive.

A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

Given: Money received in first four months: $50, $52, $55, %59.

To find: Money received in tenth month.

Finding:

As we can see, the pattern followed here is: increment in each amount received each month by $1. Thus it is an arithmetic progression.

That is: 50, 52 (0+2), 55 (2+3), 59 (2 + 3 + 4) and so on.

Thus, for the tenth month, we can use the formula of recursion, given by: [tex]a_n=a_{n-1}+d[/tex], n ≥ 1.

For a₁ = 50, a₂ = a₁ + 2

=> a₂ = 50 + 2

This way, a₅ = a₄ + 5

=> a₅ = 59 + 5 = 64

a₆ = a₅ + 6

=> a₆ = 64 + 6 = 70

a₇ = a₆ + 7

=> a₇ = 70 + 7 = 77

a₈ = a₇ + 8

=> a₈ = 77 + 8 = 85

a₉ = a₈ + 9

=> a₉ = 85 + 9 = 94

a₁₀ = a₉ + 10

=> a₁₀ = 94 + 10 = 104

Thus, the payment received in tenth month will be $104.

The formula so used is recursive, as the consequent values of the given arithmetic sequence are obtained from the preceding values.

The solution to given equation 2(5 - 10x) + 8x = -19x + 52 is x = 2

In this question, we have been given an equation:

2(5 - 10x) + 8x = -19x + 52

We need to solve given equation for x.

2(5 - 10x) + 8x = -19x + 52                 ................(Given equation)

10 - 20x + 8x = -19x + 52                   ................(Evaluate the bracket )

10 - 12x + 19x = 52                             ...............(Add 19x on each side)

10 + 7x = 52

7x = 52 - 10                                        ...............(Subtract 10 from each side)

7x = 42

x = 42/7                                              ..............(Divide each side by 7)

x = 6

The equation of the line in slope-intercept form passing through the point (-2 , 1) and perpendicular to 3x + y = 1 is y = (1/3)x + 5/3.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The slope-intercept form of the equation of a line is given by the formula:

y = mx + b

where m is the slope of the line

b is the y- intercept

If the line is perpendicular to 3x + y = 1, then their slopes are negative reciprocal of one another. To get the slope, m, of the equation, express it in slope-intercept form.

3x + y = 1

y = -3x + 1

m = -3

m = 1/3

Substitute the values of the slope and the point to solve for the y-intercept, b.

y = mx + b

1 = 1/3(-2) + b

b = 5/3

Write the equation of the line by plugging in the value of the slope and y-intercept.

A line is seen on the graph. The horizontal displacement is 2 units, and the graph's rate of change is 0.5.

Point A's coordinates are: (2,1).

Point B's coordinates are: (4,2).

The coordinates of the point change from (2.1) to (2.1) as you go from point A to point B. (4,2).

Consequently, the change in x-coordinate is what determines the point's horizontal displacement and will be,

4 2 2

Therefore, the horizontal displacement is two units.

The vertical displacement is also one unit.

Now, the graph's rate of change may be calculated by looking at the graph's line's slope.

The rate of change will thus be,

m = y2- y1 / x2 - x1

m =2-1 / 4-2

m = 1/2

On solving the equations, the total cost is 25.86.

The cost of ham is $4.80 a pound.

The cost of cheese is $6.3 for a pound.

Cheese weighing pounds was provided for $14.76.

Let "a" represent the cost of a pound of ham, and "b" represent the cost of a pound of cheese.

Given the available information,

1.3a + 0.8b = 11.28 —— (1)

Step-by-step explanation:

please check with your calculator first

The value of x for the equation 1/4 - x = x/8 is x = 2/9.

According to the given question.

We have an equation 1/4 - x = x/8.

As we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.

Here, we have to find the solution of the equation 1/4 - x = x/8 for x.

So, the solution of the given equation 1/4 - x = x/8 for x is given by

1/4 - x = x/8

⇒ 1/4 = x/8 + x           (adding x both the sides)

⇒ 1/4 =  x + 8x/8  

⇒ 1/4 = 9x/8

⇒ (1/4)(8)  = 9x

⇒ 2 = 9x

⇒ x = 2/9           (dividing both the sides by 9)

Hence, the value of x for the equation 1/4 - x = x/8 is x = 2/9.

We have a polynomial function whose graph intercepts the horizontal axis at -7, 8, and 15.

We have to identify the polynomial.

A polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).

According to the question -

x = -7, 8, 15 are the horizontal or the x - axis intercepts of the graph of the polynomial.

This means for -

x = -7

x = 8

x = 15

the polynomial (say f(x)) is equal to 0.

Therefore, x = -7 , x = 8 and x = 15 are the solutions of the polynomial f(x).

Then -

(x + 7) , (x - 8) and (x - 15) are the factors of this polynomial. Therefore -

f(x) = (x + 7)(x - 8)(x - 15)

f(x) = [tex](x^{2} -x-56)(x-15)\\[/tex]

The function f(x) = |x| + 5 undergoes horizontal shrinking by a factor of 3 to get; f(x) = |¹/₂x| + 5

There are different ways of transforming a function such as dilation, translation, reflection, stretching, shrinking e.t.c

Now, To stretch or shrink the graph in the y direction, what needs to be done is to multiply or divide the output by a constant. Now, f(2x) simply means that the function f(x) is stretched in the x direction by a factor of 2,. Meanwhile, f(¹/₂x) means that the function f(x) is shrunk in the x direction by a factor of 2 (or stretched by a factor of ¹/₂).

Now, we are told that the function f(x) = |x| + 5 undergoes horizontal shrinking by a factor of 3. Applying the above rule for shrinking gives us;

Tables cost $800 each, while chairs go for $200 each in an online furniture retailer. The store must sell at least $8000 worth of chairs and tables each day and can only ship a maximum of 19 pieces of furniture per day. Find the bare minimum of tables that the shop must sell to satisfy the requirements if 7 chairs were sold.

If  chairs were sold, the minimum number of tables that the store must sell in order to meet the requirements is 4 tables.

Let x be number of chairs

y be number of tables

Given every day, the store can ship at most 19 pieces of furniture

Then we can write x+y=19--------->equation(1)

Given an online furniture store sells chairs for $200 each and tables for $800 each.

200x is the revenue of number of chairs.

800y is the revenue of number of tables.

And given must sell a minimum of $8000 worth of chairs and tables.

Then we can write 200x+800y=8000---------->equation(2)

We have to find out If 7 chairs were sold, determine the minimum number of tables that the store must sell in order to meet the requirements.

When x=7 what is y=?

By substituting x=7 in equation (1)

7+y=19

y=19-7

y=12

Now, substitute the x=7 in equation(2)

200(7)+800y=8000
