Answer: -3x^3-28x^2-x+14

Step-by-step explanation:

(3x-2)(-x^2-10x-7)

1: We would usually use the FOIL method, but since we don't have binomials we are going to start with the first number in our problem.

3x x -x^2=-3x^3

3x x -10x= -30x^2

3x x -7= -21x

-2 x -x^2=2x^2

-2 x -10x= 20x

-2 x -7=14

2. Add like terms

-3x^3-28x^2-x+14

Determining the cause of the problem, characterizing the problem, identifying, prioritizing, and choosing potential solutions, as well as putting the solution into action, all have values of 83 for f.

-74 f = -6,142 ⇒ f = -6,142 / -74 ⇒f = 83 .

One-step equations can be solved using any one of the following four methods: adding, subtracting, multiplying, or dividing. Both sides of an equation will stay equal if the same integer is added to both sides. A mathematical expression should be evaluated according to a rule known as the order of operations.

The PEMDAS acronym can help us recall the following in that order: parentheses, exponents, multiplication and division (left to right), addition and subtraction (from left to right). A balance scale is like an equation. The scale (or equation) will become out of balance if we add or subtract from one side. Mathematical equations must ALWAYS be balanced such that both sides are equal when the equation is completed.

The quotient between the two fractions will give:

(4/6)÷(3/12) = 8/3

Here we want to find the quotient between the fractions 4/6 and 3/12.

The quotient between any two fractions a/b and c/d can be solved as:

(a/b)÷(c/d) = (a*d)/(b*c)

Then our quotient can be solved in the following way as:

(4/6)÷(3/12) = (4*12)/(3*6)

(4*12)/(3*6) = (48/18)

Now we can simplify that fraction, if we divide both numerator and denominator by 2, we will get:

24/9

Now we can divide both by 3, then we will get the simplified fraction:

8/3.

You want the price of a bagel and a can of OJ if 2 bagels and 1 can costs $8, and 3 bagels and 2 cans cost $13.

You can write an equation for the value of each purchase. The cost of a bagel can be represented by 'b', and 'j' can be used for the cost of an orange juice.

The coefficients of j are related by a factor of 2, so we can make the sum of coefficients of j be zero if we subtract the second equation from 2 times the first:

  2(2b +1j) -(3b +2j) = 2(8) -(13)

  b = 3 . . . . . . . . . . . . . . simplify

Now, we can use this value in the first equation to find j:

  2(3) +1j = 8

  1j = 2 . . . . . . . . . subtract 6

A bagel costs $3, and a can of orange juice costs $2.

The common denominator of y + [(y - 3)/3] in the complex fraction {y + [(y - 3)/3]}/(5/9 + 2/3y) is 5y + 6.

The Latin word "nomen," which also appears in words like "nominate" and "nomenclature," is the root of the English word "denominator," which means "name." And that's essentially what a fraction's denominator does: it "names" or denotes the kind of fraction that is specified by the numerator (the top part).

step1

{y + [(y - 3)/3]}/(5/9 + 2/3y)

multiply and divide with ‘9y'

9y/9y.{y + [(y - 3)/3]}/(5/9 + 2/3y)

9y.y + 9y.y - 3/3 / 9y(5/9) + 9y(2/3y)

9y.y + 3y(y - 3) / 9y(5/9) + 9y(2/3y)

9y.y + 3y(y - 3) / y.5 + 9y.2/3y

9y2 +3y2 -9y / 5y +6

12y2 - 9y / 5y + 6

The denominator will be 5y + 6

The graph of the image of the rectangle DEFG after 270° rotation counterclockwise is created using Microsoft Word and included here in the exercise

A pair of numbers called coordinates can be used to determine the position of a point or shape in a two-dimensional plane. A point's position on a 2D plane is described using the phrases "x-coordinate" and "y-coordinate."

A specific point on a grid, also known as a coordinate plane, is identified by coordinates, a pair of numbers (also known as Cartesian coordinates), or sporadically a letter and a number. The two axes of a coordinate plane, which has four quadrants, are the x (horizontal) and y (vertical) axes (vertical).

To find a point's coordinates in a coordinate system, perform the opposite.

Starting at the point, slide up or down a vertical line until you reach the x-axis. It's where your x-coordinate is.

Repeat the preceding procedures while adhering to a horizontal line to obtain the y-coordinate. The x and y coordinates can be used to find a location on the coordinate axes. The x and y coordinates of two points can be used to determine their separation. Using the x and y coordinates for two points simplifies the process of determining a line's slope.

The coordinates of the vertices of the rectangle DEFG are;

D(7, 8), E(10, 8), F(10, 9), G(7, 9)

A rotation of 270° counterclockwise about the origin gives;

Point of preimage = (x, y), point of image after the rotation = (y, -x)

The preimage point D(7, 8) has the image point as D'(8, -7) after the 270° CCW rotation

Similarly, after the 270°CCW rotation, we have;

The preimage point E(10, 8) has an image at E'(8, -10)

The preimage point F(10, 9) has an image at F'(9, -10)

The preimage point G(7, 9) has an image at G'(9, -7)

Cost for a large sandwich roll = $0.25

Cost for a small sandwich roll = $0.15

Let x be the number of small rolls that Melissa ordered.

Then number of large rolls she ordered = x + 130

Total cost for the rolls = 0.25(x + 130) + 0.15x

Melissa spent less than $63.

0.25(x + 130) + 0.15x < 63

If seven pound of fertilizer can cover 1400 square feet, 2 pounds of fertilizer can cover 400 square feet.

Therefore the answer is 400 square feet.

If seven pounds of fertilizer can cover 1400 square feet, we can set up the following proportion:

7 pounds / 1400 square feet = x pounds / y square feet

So y square feet = ( x pounds × 1400 square feet) / 7 pounds

To find out how many square feet can be covered by 2 pounds of fertilizer, we can solve for y by substituting in 2 for x:

y square feet = ( 2 pounds × 1400 square feet) / 7 pounds

y square feet = 2 × 1400 / 7

y square feet = 2800 / 7

y square feet = 400

Answer:One

Step-by-step explanation:

The two main types of coordinate systems used in mathematics and physics are Cartesian and Polar Coordinates.

A coordinate system is a system used to identify and locate a point in space. It is the basis for maps, navigation and surveying. Coordinate systems can be two-dimensional or three-dimensional, and can use a variety of units such as latitude, longitude, and feet. Coordinate systems are used in a variety of fields such as engineering, architecture, geology, and navigation. Coordinate systems help to identify and locate points in space and are essential for charting and mapping the physical world.

Cartesian Coordinates, named after the French mathematician and philosopher René Descartes, use a two-dimensional plane to represent points with an x-axis and a y-axis. These coordinates are expressed as ordered pairs (x,y) and represent points in relation to the origin (0,0). This can be used to plot graphs and equations, and is the most commonly used coordinate system.

Polar Coordinates are based on a two-dimensional plane centered on a pole. Points are expressed as ordered pairs (r,θ) where r is the distance from the pole and θ is the angle from the polar axis. This coordinate system is useful for finding distances and angles in a circle. It is used frequently in physics and astronomy.

To determine whether the sequence converges or diverges, we can use the Squeeze Theorem.

We can see that

[tex]4/(n + 5n^2) < = An < = (4 + 3n^2)/(n + 5n^2)[/tex]

As n tends to infinity, [tex]4/(n + 5n^2)[/tex]  tends to 0 and[tex](4 + 3n^2)/(n + 5n^2)[/tex]  tends to[tex]4/(5n^2)[/tex]  which also tends to 0.

So by the Squeeze Theorem, we can say that An tends to 0 as n tends to infinity. Hence the limit of the sequence is Lim n-> An = 0

We can also see that the numerator of An is a constant and the denominator is a polynomial with degree 2. Since the denominator's degree is greater than the numerator, the limit will be zero as n -> infinity.

Therefore, the sequence converges to 0.
