Step-by-step explanation:

The solution of given system of equations are x = -1.146 and           x = 4.833

In this question, we have been given a system of equations.

4x^ 2 -3x+6=2x^ 4 -9x^ 3 +2x

We can write it as:

y = 4x² - 3x + 6

y = 2x^4 - 9x³ + 2x

We need to find the solution of given system of equations.

Consider the following graph of given system of equations as shown below.

In graph both the equations intersect at two points (-1.146, 14.687) and (4.833, 84.945)

Point of intersection gives the solution of the equations.

x-coordinate of the intersection of graph gives the solution because function depends on x.

Therefore, the solution of given system of equations are x = -1.146 and           x = 4.833

The equivalent expressions of One-third + 8 d + StartFraction 5 Over 7 EndFraction are option B,D and G.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, the given expression is :

One-third + 8 d + StartFraction 5 Over 7 EndFraction

and, the expression equivalent to this are :

1) 8 d + one-third + StartFraction 5 Over 7 EndFraction

2) One-third + StartFraction 5 Over 7 EndFraction + 8 d

3) StartFraction 5 Over 7 EndFraction + one-third + 8 d

The total sales done by Madelyn Logan is $975,000.

Madelyn Logan earns $58,000 in total.

Madelyn Logan's total commissions are;

$58,000 - $19,000 (base salary) = $39,000.

That is, $39,000 equals 4% of her sales.

So,

0.04x = $39,000, in which x would be the total sales amount.

Then, x = $39,000 /0.04

x = $975,000.

Therefore, Madelyn Logan must sell the goods of worth $975,000. for making the amount of $58,000.

We can rearrange it to the standard form perimeter a = s - b - C/2

In arithmetic, what is a perimeter?

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

The answer to your question is a = s - b - C/2

To solve for "a", we must get "a" on it's own side of the equal sign. We can first subtract "s" from both sides:

0 = a + b + C/2 - s

Then, we can subtract a from both sides:

-a = b + C/2 - s

Finally, we divide both sides by -1, so a is by itself.

a = -b - C/2 + s

And we can rearrange it to the standard form:

a = s - b - C/2

The inequality graph that represents n ≤ 3 is in the diagram attached below.

An inequality can be solved just like a normal equation by finding the possible values of the variable.

Given the inequality, 6n − 18 ≤ −n + 3, combine like terms

6n − 18 + 18 ≤ −n + 3 + 18

6n ≤ - n + 21

Add n to both sides of the inequality

6n + n ≤ - n + 21 + n

7n ≤ 21

Divide both sides by 7

7n/7 ≤ 21/7

n ≤ 3

This means that the values of n are from 3 and below.

Answer:1/4 of robot

Step-by-step explanation:

Based on the selling price of the property in 6 years, the present value of the selling price is $3,313,315.

This amount is NOT attractive.

Based on the annual cash flows from the property, the present value of the cash flows is $4,640,991.40.

The property will then be attractive

The present value of the selling price can be found as:

= Selling price / (1 + rate) ^ number of years

= 4,700,000 / (1 + 6%)⁶

= $3,313,315

This amount is less than the buying price of the property today so the property is not attractive as it would result in a present value loss.

The present value of the cashflows will be the present value of an annuity because the rent is constant:

= Rent value x Present value interest factor of an annuity, 6 years, 6%

= 270,000 x 4.91732

= $1,327,676.40

The present value of the property then becomes:

= 1,327,676.40 + 3,313,315

= $4,640,991.40

The property then becomes very attractive because the present value gives a gain over the selling price of $3.7 million.

x is the largest angle, y is the next largest angle and z is the smallest angle

Also, from the information,

"The measure of the largest angle is 20 degrees less than twice the sum of the measure of the other two angles"

That is,

x = 2(y + z) - 20

The polynomial which models the company's sales in thousands of dollars will be 4.4x² + 4x.

A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.

The profit is given as,

Profit = Selling price - Cost price

Sales volume for an auto manufacturer may be calculated as 7.8x² + 3.2x + 3.5 and costs as 3.4x² - 0.8x + 3.5.

The net profit by subtracting cost from sales will be

Net profit = (7.8x² + 3.2x + 3.5) - (3.4x² - 0.8x + 3.5)

Net profit = 7.8x² + 3.2x + 3.5 - 3.4x² + 0.8x - 3.5

Net profit = 4.4x² + 4x

Answer:

Step-by-step explanation:

The Pascal's Triangle expansion of (3 x-1)^4 is mathematically given as

[tex]$$\begin{aligned}&1(3 x)^4(-1)^0+4(3 x)^3(-1)^1 +6(3 x)^2(-1)^2+4(3 x)^1(-1)^3 +1(3 x)^0(-1)^4\end{aligned}$$[/tex]

This is further explained below.

Generally,  the equation for the expansion is  mathematically given as

(3 x-1)^4

Pascal's Triangle can be displayed as such:

1

1-1

1-2-1

1-3-3-1

1-4-6-4-1

The triangle can be used to calculate the coefficients of the expansion of (a+b)^n by taking the exponent n and adding 1 .

The coefficients will correspond with line n+1 of the triangle.

For (3 x-1)^4, n=4 so the coefficients of the expansion will correspond with line 5.

The expansion follows the rule

(a+b)^n=c_0 a^n b^0+c_1 a^{n-1} b^1+c_{n-1} a^1 b^{n-1}+c_n a^0 b^n

The values of the coefficients, from the triangle, are $-4-6-4-1.
