The correct first step in solving the inequality –4(3 – 5x)≥ –6x + 9 is through multiplicative distributive property

We will calculate the value of x while showing the first step in solving the inequality, to provide better idea on complete solution. The correct first step is by using multiplicative distributive property as shown -

Rewriting the inequality -

–4(3 – 5x)≥ –6x + 9

Multiplying the values in each side of inequality

-12 + 20x ≥ -6x + 9

Rewriting the inequality according to terms

20x + 6x ≥ 9 + 12

Performing addition on each side of the equation

26x ≥ 21

So, x ≥ 21/26

Last month, ed spent $50 in all. He spent 40% of the money at the movies. So $20 Ed spend at the movies.

In the given question we have to find how much money ed spend at the movie.

Last month Ed spend total $50.

He spent 40% of the money at the movie.

Total money spent by Ed last month = $ 50.

Percentage of the money spent at the movies = 40%

Money spend by Ed at the movies=Percentage of the money spent at the movies * Total money spent by Ed last month

Money spend by Ed at the movies= 40% * $50

There is no sufficient evidence at the 0.05 level of significance that the percentage is not 58%.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given percentage = 98%

alpha = 0.05

First we will design the null hypothesis.

null hypothesis: p greater than or equal to 0.58

and alternate hypothesis: p is less than to 0.58

The null hypothesis shows that 58% or more readers owns a Rolls Royce.

The alternative hypothesis shows less than 58% of the readers own a rolls Royce.

Solution to the system of linear inequalities 2x - 3y <12, graph plotted below.

What is inequality ?

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare two values. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign in between. Sometimes it can be about a "not equal to" relationship, where one thing is more than the other or less than. In mathematics, an inequality is a relationship that results in a non-equal comparison between two numbers or other mathematical expressions.

In this case, the inequality 2x - 3y <12

Related formula: 2x - 3y = 12.

Having x-intercept means

y = - intercept

Also, 2(0) - 3(0) < 12.

The dimension of the Box is equal to 3×6×6 where the Height = 3m and the length of base = 6m

We have the volume of the box as

V= 108 cubic meters

Let 'a' be the height of the box and 'b' be the one side of the base of the box.

Therefore the formula for volume is

Volume = ab²

108 =  ab²

=> a = 108/b²    ....(1)

Now the surface area of the box is,

S = b² + 4ab   ....(2)

From equations (1) and (2) we get,

Sa = b² + 4× (108/b²) × b

Sa = b² + 432 / b²  ....(3)

Now for the least possible surface area differentiate equation (3) we get,

d(Sa)/db = 2b - 432/b²   ....(4)

Now put the equation (4) equal to zero we get,

2b - 432/b² = 0

2b = 432/b²

b³ = 216

b = 6

Now put the value of b in equation (1) we get,

The measure of [x] in the triangle will be 61°.

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a triangle as shown in the image attached.

The given triangle is a isosceles triangle. So, we can write -

[x] + [x] + 58 = 180

2x + 58 = 180

2x = 122

x = 61

Therefore, the measure of [x] in the triangle will be 61°.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint.

Having $21,000 after investing 11 years with an annual simple interest rate of 4.5% means that the principal amount that Cindy's mom invested when Cindy turned 10 years old was $14,046.82

Simple interest rate is calculated by multiplying the interest rate given in a period of time with the principal without any compounding, and multiply it by the period of time that the principal is invested.

Given that the interest rate is at 4.5% annually, we will need to convert the percentage into a decimal with the following calculation:

4.5/100=0.045

The principal is invested when Cindy was 10 years old and by the time Cindy turned 21 years old the total investment accumulated is $21,000 within 11 years. We will then need to figure out the initial amount invested with the following formula:

P = A / (1 + rt)

Where P is the principal amount, A is the total amount of principal including the interest, r is the interest in decimal, and t is the number of years the money is invested.

P = 21000/(1+(0.045×11))

P = 14,046.82

The solution for p(-2) in the function when the function p(n) = 2n is -2

From the question, we have the following equation that can be used in our computation:

p(n)=2n

To make the equation legible, we need to rewrite it

So, we have the following representation

p(n) = 2n

Also from the question, we have

p(-1)

This means that the value of n is -1, and we calculate p(n) when n = -1

Substitute the known values in the above equation, so, we have the following representation

p(-1) =  2 * -1

So, we have the following equation

p(-1) =  2 * -1

There is no constant to add or subtract to both sides of the equation

So, we have the following representation

p(-1) =  -2

Hence, the solution is -2

A solution to a system of equations is a value that, when substituted for unknown variables, causes the equations to be true.

A system of linear equations is made up of two or more linear equations made up of two or more variables, and all equations in the system are considered at the same time.

The set of all values that, when substituted for unknowns, make the equations true is referred to as the solution of a system of equations.

To find the unique solution to a system of linear equations, we must find a numerical value for each variable in the system that simultaneously solves all of the equations in the system.

Some linear systems have no solution, while others have an infinite number of solutions.

What is inequality?

An inequality in mathematics depicts the connection between two values in an algebraic statement that are not equal. One of the two variables on the two sides of the inequality may be greater than, greater than or equal to, less than, or less than or equal to another value, according to inequality signals.

5(x – 2)(x + 4) > 0

First we solve for x, we replace the inequality sign by = sign

5(x – 2)(x + 4) = 0

Divide both sides by 5

(x – 2)(x + 4) = 0

Now we set each factor =0  and solve for x

x-2 =0 , so x= 2

x+4 =0, so x= -4

Now we use number line and make three intervals

First interval -infinity to -4

Now we check each interval with our inequality

First interval -infinity to -4, pick a number in this interval and check with our inequality. lets pick -5
