Answer:

B

Step-by-step explanation:

To find the answer, we can use the point-slope form:

y-y_1=m(x-x_1)

Where (x₁, y₁) is a point and m is our slope.

Let's let our point (4, 1/3) be (x₁, y₁) respectively.

We also know that our slope is 3/4. So, substitute 3/4 for m.

This yields:

y-\frac{1}{3}=\frac{3}{4}(x-4)

The choice that represents this is B.

So, our correct answer is B.

And we're done!

<h3>Answer:</h3>

y -  \frac{1}{3}  =  \frac{3}{4} (x - 4)

<h3>Step-by-step explanation:</h3>

Given the line passes through (4, 1/3) and it's slope is 3/4

y = mx + c

slope =  m

m =  \frac{3}{4}

y =  \frac{3}{4} x + c

At (4, 1/3)

\frac{1}{3}  =  \frac{3}{4} (4) + c

c =  -  \frac{8}{3}

y - intercept =  -  \frac{8}{3}

The equation of the line:

y =  \frac{3}{4} x -  \frac{8}{3}

The answer is:

y -  \frac{1}{3}  =  \frac{3}{4} (x - 4)

*if you expand the equation above you will get the equation of line you initially got*

rodikova [14]

Answer:

432 characters

Step-by-step explanation:

There are 3 feet in a yard which means there are 36 inches in a yard since one foot is equal to 12 inches. Each inch contains 12 characters so you would multiply 36 by 12 to get 432.

Nine and one half less than four and one half times a number is greater than 62,5. Which of the following represents
morpeh [17]

Answer: (16,O0) That is 16 to positive infinity

Step-by-step explanation:

4.5x - 9.5 > 62.5

4.5x > 62,5 + 9.5

4.5x > 72

x > 72/ 4.5

x> 16

So all real numbers greater than 16 is the solution set.

(16,O0)

I wish I had the infinity symbol on this keyboard!

PLS HELP ALGEBRA 2 QUESTION ASAP 5 STARS AND BRAINLIEST what type of polynomial is <img src="https://tex.z-dn.net/?f=-5x%5E%7B4%
devlian [24]

Answer:

Binomial

Step-by-step explanation:

Edited to add:

It can also be called a binomial because there are 2 unlike terms x and y. I'm not sure what you are studying, so it may be better to go with binomial. The Quartic is when you are looking at the degree of a single term polynomial.

You can name a polynomial based on terms, or based on degrees.

If it's based on degree it would be bi-quadratic, because it's ^4 and you have 2 different terms. If you're looking at terms it would be binomial because you have x and y to solve for.

The degree of terms is a major deciding factor whether an equation is homogeneous or not. A polynomial of more that one variable is said to be homogeneous if the degree of each term is the same. For example, 2x^7+5x^5y^2-3x^4y^3+4x^2y^5 is a homogeneous polynomial of degree 7 in x and y.

You have a 4 term polynomial with 2 variables x and y. The highest degree in your equation is 5 (4 + 1 from the first term) so the degree of the multivariable polynomial expression is 6.

All these answers are correct, it just depends what you're studying. If some of these words are new, and others you recognize from class or your book, go with the one that looks familiar.
