The LCM of the numbers 1 - x² and (x - 1)³ is (1 - x²)(x - 1)

An equation is a expression that shows the relationship between numbers and variables.

The least common multiple (LCM) of a set of numbers is the smallest number that can be divisible by the set of numbers

Given the numbers:

1 - x² and (x - 1)³

(1 - x²) = (1 - x)(1 + x) = -1(x - 1)(x + 1)

(x - 1)³ = (x - 1)(x - 1)(x - 1)

The LCM = -1(x + 1)(x - 1)(x - 1) = -1(x² - 1)(x - 1) = (1 - x²)(x - 1)

The LCM is (1 - x²)(x - 1)

Answer:

A, B,D

Step-by-step explanation:

Step-by-step explanation:

multiply both equations with factors so that the terms of the targeted variable (in our case x) have the same constant factor. and then we can subtract one equation from the other, abd the variable is eliminated in the result.

in our case the least common multiple of 4 and 9 is 36.

so, we multiply equation 1 by 9, and equation 2 by 4, abd then we subtract

36x - 54y = 90

- 36x + 8y = 28

-------------------------

0 -62y = 62

so, x is "eliminated", and we can solve for y : y = -1.

and then we can use one of the original equations to solve for x.

e.g.

9x + 2×-1 = 7

9x - 2 = 7

9x = 9

x = 1

Answer:

First, we'll need to find the LCM (least common multiple) which, in this case, is 36. Now that we know this, we can get 4x and 9x to be 36x and -36x so that they can cancel out. To do this, we have to multiply Equation 1 by 9 and Equation 2 by -4.

9(4x - 6y = 10) is equivilant to 36x - 54y = 90

-4(9x + 2y = 7) is equivilant to -36x - 8y = -28

Now that we have our new system of equations, we can proceed with the process of elimination! The first step is to add the two equations together. This will result in:

-62y = 62 we have successfully eliminated x!

The last step will be to divide both sides by -62

-62y/-62 = 62/-62

y = -1

The best estimate for the perimeter of the triangle will be 23.7 inches.

In Δ ABC ∠B =90° , ∠C = 30° , ∠A = 60° and hypotenuse AC = 10 inches

It has been described in the attachment.

Now, we shall calculate side AB and BC by using Trigonometric Ratios.

Sin 30° = AB / AC

or,  AB = 10 × Sin 30° = 10 × 0.5 = 5 inches

And, Cos 30° = CB / AC

or,CB =  10 × Cos 30° = 10 × 0.866 = 8.66 inches

Now, we calculate the perimeter of the given triangle

The perimeter of the triangle is = AB + BC + CA

                                                     = (5.0 + 8.66 + 10.0 ) inches

                                                     = 23.66 inches ≈ 23.7 inches

Hence, the best estimate for the perimeter of the triangle will be 23.7 inches.

The cost to customer after seven months of service is equal to $171.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁)

Where:

Next, we would set up or write an equation that shows the relationship between the months of service and the total charges as follows;

y - 81 = 18(x - 2)

By making "y" the subject of formula, we have the following:

y = 18x - 36 + 81

Number of servings Cate can have is given by the equation A = 16 servings

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of servings be represented as A

Now , the equation will be

The number of cups of rice Cate has = 2 cups

The number of cups of servings Cate divides = 1/8 cups

So ,

The number of servings A = number of cups of rice Cate has / number of cups of servings Cate divides

Substituting the values in the equation , we get

The number of servings A = 2 / ( 1/8 )

On simplifying the equation , we get

The number of servings A = 2 x 8

The number of servings A = 16 servings

Therefore , the value of A is 16 servings

The percent of the bug eaten each day is 67% and the percent of the bug remaining each day is 33%.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

f(x) = 500 (0.67)ˣ

Part A :

x = 0 ⇒ f(x) = 500 (0.67)⁰ = 500

x = 1 ⇒ f(x) = 500 (0.67)¹ = 335

x = 2 ⇒ f(x) = 500 (0.67)² = 224.45

x = 3 ⇒ f(x) = 500 (0.67)³ = 150.3815

Part B :

Here 0.67 is the decay rate.

That is the rate of decay of the bug is 0.67.

67% of the bugs are decaying with each day.

Part C :

Percent of bugs remaining each day = 100% - 67% = 33%

Part D:

f(x) < 40

The time taken by 3 electricians to complete the work is 9 1/3 hours.

When one quantity's value rises relative to another's decrease or vice versa, it is said that the two are inversely proportionate.

It implies that the two quantities exhibit opposing behaviors in nature. For instance, the relationship between time and speed is inverse.

If x and y are inversely proportionate to each other

=> xy = k    [ where 'k' is proportionality constant ]

Here we have

The time required to complete a job varies inversely to the number of people working. It took 4 hours for 7 electricians to wire a building.

Let x be the time and y be the number of people

Given that the time required to complete a job varies inversely to the number of people working.  

=> xy = k ---- (1)  [ Since they are inversely proportional to each other ]

When it comes to geometry, a coordinate system is a technique that uses one or more integers or coordinates to specify the exact location of points or other geometrical objects on a manifold, such as Euclidean space. Locating a point or item on a two-dimensional plane requires the usage of pairs of integer coordinates. Two numbers known as the x and y coordinates serve as a description of a point's location on a 2D plane. a collection of figures that signify exact locations. Most often, the figure contains two numerals. The first number denotes the distance from front to rear, and the second number denotes the distance from top to bottom. In (12.5), for example, there are 12 units below and 5 above.
