What is (11-3) divided by 2+1 step by step

The best description of the given inequality is;

Felicia has 29 buttons in her collection. She will collect 12 new buttons every year. Felicia collects buttons for k years. For what values of k will Felicia have at least 120 buttons?

Hence, Option B is true.

What is inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

The inequality is given as;

⇒ 120 ≤ 12 k + 29

It can be written as;

12k + 29 ≥ 120

Now, We have;

A constant term = 29

And, Variable with number = 12k

Which is multiple of the number of buttons collected and the number of years k.

The sign is ''greater than equal'' to with 120, that's mean 'at least 120'

So, The best description of the given inequality is;

Felicia has 29 buttons in her collection. She will collect 12 new buttons every year. Felicia collects buttons for k years. For what values of k will Felicia have at least 120 buttons?

Hence, Option B is true.

Answer:

x<-27/4

​

Step-by-step explanation:

−4(2−x)1<−35

Multiply −4 and 1 to get −4.

−4(2−x) <−35

Use the distributive property to multiply −4 by 2−x.

−8+4x<−35

Add 8 to both sides.

4x<−35+8

Add −35 and 8 to get −27.

4x<−27

Divide both sides by 4. Since 4 is positive, the inequality direction remains the same.

Comparing the price of a 50000 mercedes to the price of a 40000 lexus The absolute price difference is 10000 while the relative price difference is 20%

Absolute difference refers to the gap between the prices. This implies the amount one has more than the other.

This could be solved by subtraction an is solves as follows:

price of a mercedes -  price of a lexus

= 50 000 - 40 000

= 10 000

Here, the price difference is expressed in percentage of the reference price being checked with. This is achieved using the formula below:

( price of a mercedes -  price of a lexus ) / price of a mercedes * 100

= (( 50 000 - 40 000 ) / 50 000 ) * 100

= (( 10 000 ) / 50 000 ) * 100

= ( 0.2 ) * 100

= 20%

Point Q will be located at 27 / 7.

We are given the points:

P = - 26

R = - 5

Let Q = x

Now, we also have the ratio as:

PQ : QR = 5 : 2

PQ = Q - P

PQ = x - ( - 26 )

PQ = x + 26

QR = R - Q

QR = - 5 - x

Now, we know that:

PQ / QR = 5 / 2

2 PQ = 5 QR

It should be noted that in order to measure the value, the measurement have to be in the same unit.

The fundamental idea in the study of science and mathematics is measurement. The qualities of an object or event can be quantified so that we can compare them to those of other objects or occurrences. When discussing the division of a quantity, measurement is the word that is used the most frequently.

Measurement is crucial in establishing connections across different branches of mathematics. For instance, it gives the use of math abilities and spatial concepts a rich and meaningful context. Measurement also establishes connections between mathematics and other academic disciplines.

From the information, it was illustrated that the boys all had measurement of trees taken. Therefore, it should be noted that since they are in different units, it cannot be done.

In this case, the reason is that in order to measure the value, the measurement has to be in the same unit. This will make it easier to do the calculation.

The slope of the line is -5 / 4.

The slope of a line is a measure of its steepness.

The slope of the line is the ratio of the rise to the run, or rise divided by the run.

Therefore,

slope = change in y / change in x

slope = y₂ - y₁ / x₂ - x₁

Using (1, -3)(-3, 2)

x₁ = 1

x₂ = -3

y₁ = -3

y₂ = 2

Therefore,

slope = 2 - (-3) / -3 - 1

slope = 2 + 3 / -4

slope = - 5 / 4

The growth factor for the annual rate of change of +12.5 % is 1.125.

A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.

With the function displayed to the right, you may represent exponential growth or decay.

A(x) = a( 1 + r)ˣ

Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.

Now, we have the annual rate of change as:

r = + 12.5 % = + 12.5 / 100 = + 0.125

From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.

So, let B = 1 + r

B = 1 + r

B = 1 + (+ 0.125)

B = 1.125

Now, the value of B is greater than 1 therefore, the corresponding growth factor is 1.125.

-x² + 7x + 5 is the domain of all real numbers.

Function operations are the rules we use to solve functions. There is a specific way to deal with function addition, multiplication, and division.

Let the two functions be f and g then f(x) = 7x + 5 and g(x) = x².

we have to calculate (g - f)(x)

Which is equivalent to:

(g - f)(x) = g(x) - f(x)

Taking the two functions and substituting them into this expression, we get,

g(x) - f(x) = (7x + 5) - (x²)

simplifying the above function, we get

g(x) - f(x) = -x² + 7x + 5

Therefore, (g - f)(x) = -x² + 7x + 5.

We must also determine the domain of the new function. However, because this is a second-order function with no denominators, logarithms, or roots, there are no restrictions on the value of x; thus, the domain is all real numbers.

A square in geometry is a two-dimensional plane figure having four equal sides and four equal but 90 degree angles. The characteristics of a rectangle and a square are somewhat comparable, however only the opposite sides of a rectangle are equal. So, only if all four of a rectangle's sides are the same length can it be said to be a square.

A square is a regular quadrilateral with four equal-length sides and four equal-length angles. The square's angles are 90 degrees or at right angles. In addition, the square's diagonals are equally spaced and split at a 90-degree angle. A square is another name for a rectangle with two sides that are opposite and the same length.

the equation for the parabola is:

f(x) = 2*(x + 4)*(x - 5)

We know that if a parabola has x-intercepts a and b, and a leading coefficient A, then the equation is:

f(x) = A*(x - a)*(x - b)

In this case the x-intercepts are x = -4 and x = 5, then we have:

f(x) = A*(x + 4)*(x - 5)

Now we use the fact that the parabola passes through the point (1, -40), then we have that:

f(1) = -40 =  A*(1 + 4)*(1 - 5)

        -40 = A*(5)*(-4) = A*-20
