$36.55
Explanations:
Given the following parameters
Regular price of a ticket = $43
Sales discount = 15%
Determine the discounted price
Discount price = 0.15 * 43
Discount price = $6.45
Determine the sales price
Sales price = Regular price - discount
Sales price = $43 - $6.45
Sales price = $36.55
Hence the sales price for the item will be $36.55

By definition:
Congruent figures in geometry are identical in shape and size.
This means that two figures are congruent with each other even if they are rotated, flipped or trasnlated as long as they have the identical shape and size.
For example, look at the following picture
We notice that the triangle has the same size and shaped, hence they are congruent. Furthermore we can say that the side BC is congruent to the side ZY and so on.

(-4b³ + b − 1) + (6b - 6) =
Answer:
-4b^3 + 7b - 7
Step-by-step explanation:
We have to look at terms which look like each other, for example 1b and 6b.
We can add and subtract terms which have the same degree of b.
In this question, we can safely add -1 and -6, and also b and 6b,
which gives us (-4b^3 + b - 1 ) + 6b - 6) = -4b^3 + (1+6)b +( -1 - 6) = -4b^3 + 7b - 7
The three remaining terms all have different degrees of b's (respectively 3, 1, 0), so we can't add those up any further, which tells us that this is the right answer.

What is a function?
Function, in mathematics, an expression, rule, or law that defines a relationship between : one variable (the independent variable) and another variable (the dependent variable).
A function is an equation with a single solution for y for each value of x. Each input of a particular type receives exactly one output when using a function. Instead of y, a function is frequently named f(x) or g(x). When x equals 2, we should determine our function's value because f(2) says to do so.
Given: f(x) = 3x² - 2x
g(x) = 9x² -x + 7
To find: ( f - g )(x)
thus (f-g)(x)= 3x² - 2x - ( 9x² - x + 7)
(f-g)(x) = -6x² - x - 7

Create your own thought experiment explaining why a negative divided by a negative is a positive.
Dividing two negative numbers results in a positive number.A negative number divided by a negative number produces a positive result since two negatives equal a positive.
Explaining why a negative divided by a negative is a positive
The quotient is positive when two negative values are divided.The same guidelines apply to multiplication. Divided by another negative integer, a negative number always yields a positive number.divided equally by.The solution cannot be or any other negative number because it is positive. Divide two negative numbers, and you'll always get a positive number as the result.For instance, dividing -4 by -2 yields 2.The negatives cancel out when both numbers are negative, hence the outcome is always a positive number.

PT = 36m
replace the previous values of the length of the segments and solve for x, just as follow:

Using the graph below, write two ordered pairs to show that the equation y = 15x represents the data.
By using the points (2, 30) and (4, 60) that we can see on the graph, we can see that the linear equation that models the data is:
y = 15*x
How to find the equation that models the data?A general linear equation is of the form:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), the slope is given by:
a = (y₂ - y₁)/(x₂ - x₁)
In this case we can use two points that appear on the graph, I will use the first two ones:
(2, 30) and (4, 60)
Then the slope is:
a = (60 - 30)/(4 - 2) = 30/2 = 15
Thus, the line is of the form:
y = 15*x + b
To find the value of b we use the point (2, 30), replacing these values we get:
30 = 15*2 + b
30 = 30 + b
30 - 30 = b
0 = b
We conclude that the linear equation that models the data is y = 15*x

10. Sydney wants to buy soda and juice for her birthday party. A bottle of soda costs $1.99 each and a jug of juice costs $2.49 each. If Sydney has $30, what equation could be used to find how many soda bottles and how many jugs of juice she can purchase? let x = let y = Equation
ANSWER
1.99x + 2.49y = 30
EXPLANATION
A bottle of soda costs $1.99 each and a jug of juice costs $2.49.
Sydney has $30.
Let x be the number of bottles of soda she can get.
Let y be the number of jugs of juice that she can buy.
This means that the cost of x bottles of soda is:
1.99 * x = $1.99x
This also means that the cost of y jugs of juice is:
2.49 * y = $2.49y
The total cost must be equal to $30, so this means that the total cost of bottles of soda and jugs of juice she can purchase is:
1.99x + 2.49y = 30
That is the equation that represents it.
You plan to work for 40 years and then retire using a 25-year annuity. You want to arrange a retirement income of $3500 per month. You have access to an account that pays an APR of 4.8% compounded monthly. This requires a nest egg of $610,823.48.
What monthly deposits are required to achieve the desired monthly yield at retirement? (Round your answer to the nearest cent.)
The monthly deposit that is required to achieve the desired monthly yield at retirement is $1,056.71.
What is the monthly deposit?An annuity is a series of payment that is made over a period of time. The annuity in this question would last for 25 years. When an investment is compounded monthly, it means that the investment would grow at an exponential rate once in a month.
The formula that would be used to determine the monthly payment is:
Monthly payment = future value / annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
Where:
r = monthly interest rate = 4.8% / 12 = 0.4%n = number of periods = number of compounding x number of years: 12 x 25 = 300$610,823.48 ÷ [{(1.004^300) - 1} / 0.004] = $1,056.71

Match the two lines that are parallel and the two lines that are perpendicular. Then, match the equations.
Step-by-step explanation:
A and C are parallel. equations G and E.
B and D are perpendicular (standing at a right angle = 90° to each other). equations F and H.
parallel means that both lines have the same slope.
the slope is the factor a of x when the equations look like
y = ax + b (slope-intercept form)
or
y - y1 = a(x - x1) (point-slope form)
"a" being the slope, b being the y-intercept (the y- value when x = 0), (x1. y1) being a point on the line.
the slope is specified as ratio (y coordinate difference / x coordinate difference) when going from one point to another.
the perpendicular slope to y/x is the upside down ratio and the sign is flipped.
e.g. the perpendicular slope to 5/4 is -4/5.
equation E is already in point-slope form.
the slope is 2/3, and the point (-9, -2) must be on the line.
only one line goes through the point (-9, -2) : C.
equation H is already in slope-intercept form.
the slope is 3/2, and the y-intercept is 5, meaning the line goes through the point (0, 5).
only one line goes through that point : D
equation F
2x + 3y = -21
3y = -2x -21
y = (-2/3)×x - 7
the slope is -2/3, which is perpendicular to 3/2 (equation H).
the y-intercept is -7, meaning the line goes through the point (0, -7).
only one line goes through that point : B
equation G
-2x + 3y = -6
3y = 2x - 6
y = (2/3)×x - 2
the slope is 2/3 (parallel to equation E).
the y-intercept is -2, meaning the line goes through the point (0, -2).
only one line goes through that point : A
