HELP What is the equation in slope-intercept form of the line that crosses the y-axis at 3 and is perpendicular to the line represented by y=2/5x+2

Therefore, we can classify the polynomial as a quadratic polynomial.

A polynomial is a mathematical expression that consists of variables and coefficients, and involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. Polynomials can have one or more variables and may contain multiple terms. Each term consists of a coefficient and a variable raised to a power. The degree of a term is the power to which the variable is raised, and the degree of a polynomial is the highest degree of any of its terms. Polynomials are used in many areas of mathematics, science, and engineering, such as algebra, calculus, geometry, and physics. They are used to model real-world phenomena, to solve equations, and to approximate complex functions.

Here,

To write the polynomial 14y² - x² - 3xy in standard form, we need to arrange the terms in descending order of degree (highest degree term first) and combine like terms.

First, let's rearrange the terms:

x² - 3xy + 14y²

Now, the polynomial is in descending order of degree. We don't need to do anything else to put it in standard form.

To classify the polynomial, we count the number of terms and the highest degree of those terms. In this case, there are three terms and the highest degree term is 14y², which has degree 2.

Answer:

D. 250 feet per minute

Step-by-step explanation:

According to this question, Timothy walks at constant speed. From Physics we know that speed is the magnitude of velocity and is determined by the following definition:

[tex]v = \frac{\Delta x}{\Delta t}[/tex] (1)

Where:

[tex]\Delta x[/tex] - Distance between home and mailbox, measured in feet.

[tex]\Delta t[/tex] - Travel time, measured in minutes.

[tex]v[/tex] - Walking speed of Timothy, measured in meters per second.

The distance is represented by the vertical axis of the graph, whereas the travelling time is from the horizontal axis.

If we know that [tex]\Delta x = 3,750\,ft[/tex] and [tex]\Delta t = 15\,min[/tex], then the walking speed of Timothy is:

[tex]v = \frac{3,750\,ft}{15\,min }[/tex]

[tex]v = 250\,\frac{ft}{min}[/tex]

The walking speed of Timothy is 250 feet per minute. Hence, the right answer is D.

Answer:

AZ = 12.80

Step-by-step explanation:

There are 2 triangles in the square XARS. Squares are always congruent, all sides are the same. Given that WT is 6, we can assume that RS is also 6 (because of congruency). RA is is the hypotenuse of the triangle ARS. To find AS, we can plug in the pythagorean theorem 6^2+x=^2=10^2. We end up getting square root of 64 which simplifies to 8. AS is now 8. We also know that ST is 6 since the square WRST has all congruent sides. 8+6=14 gives us line AT. TZ is 8 due to triangle XAR and the congruency theorem. Now we plug in pythagorean theorem to find AZ and we get 8^2+10^2=x^2. After simplifying the square root of 164, we see that AZ is equal to 12.80

Answer:

12.80

Step-by-step explanation:

The first equation given as 7x + ( -6 ) = 6x - 2 is True.

The second equation given as 7 + 2x = 3x + 3 = 4 is false

Given data

7x + ( -6 ) = 6x - 2

7 + 2x = 3x + 3 = 4

The first equation

7x + ( -6 ) = 6x - 2

solving for x gives

7x  - 6 = 6x - 2

7x - 6x = 6 - 2

x = 4

checking for the value

7x + ( -6 ) = 6x - 2

7 * 4 - 6 = 6 * 4 - 2

28 - 6 = 24 - 2

22 = 22

Hence we say the expression in the first equation is true

The second equation

7 + 2x = 3x + 3 = 4

7 + 2x = 3x + 3

7 - 3 = 3x - 2x

4 = x

checking for the value of x

7 + 2x = 3x + 3

7 + 2 * 4 = 3 * 4 + 3

7 + 8 = 12 + 3

15 = 15

15 = 15 ≠ 4 false

The first equation is true while the second equation is false

Answer:

[tex]y = \frac{7}{4}x - \frac{5}{4}[/tex]

Step-by-step explanation:

Equation of line K:  [tex]y = \frac{-4}{7}x + 1[/tex]

m₁ = -4/7

The slope of line I = -1 / m₁ = -1÷(-4/7)

                            = [tex]-1 * \frac{-7}{4}[/tex]

                            = 7/4

( -5 , -10) ; m = 7/4

y - y1 = m(x - x1)

y - [-10] = [tex]\frac{7}{4}(x -[-5])[/tex]

y + 10  = [tex]\frac{7}{4}(x +5)\\[/tex]

y + 10 = [tex]\frac{7}{4}x+5*\frac{7}{4}\\[/tex]

        [tex]y = \frac{7}{4}x + \frac{35}{4} - 10\\\\y = \frac{7}{4}x + \frac{35}{4} -\frac{40}{4}\\\\y = \frac{7}{4}x + \frac{35-40}{4}\\\\y = \frac{7}{4}x - \frac{5}{4}[/tex]

Answer:

42,46

Step-by-step explanation:

2n+2n+4=88

4n+4=88

4(n+1)=88

n+1=88/4

n+1=22

n=22-1

n=21

Therefore

2n=2*21=42

2n+4=2*21+4

2n+4 = 42+4 = 46

The ratio is 25:18.

This problem is related to the ratio and proportion.

here it's miles given that if the number of sedans produced by organisation x have been extra by using 8% then the quantity would be one hundred fifty % of the quantity of SUVs.

1) Let that the number of sedan produced be x and number of SUVs be y.

Now according to question,

   [tex]x+\frac{8}{100}*x =\frac{150}{100}*y[/tex]

⇒[tex]\frac{108x}{100}=\frac{150y}{100}[/tex]

⇒[tex]\frac{x}{y} =\frac{150}{108}[/tex]

∴ x : y=25 : 18

2) Now again the ratio =[tex]\frac{565000}{406800}[/tex]

                                    =[tex]\frac{5650}{4068}[/tex]

                                    = [tex]\frac{25}{18}[/tex]

So, the ratio of the number of sedans to the number of SUVs is 25:18.
