jekas [21]

Answer:

-3+6y = 9x

6y = 9x+3

y = 9/6x+3/6

y = 3/2x+1/2 ⇒ slope-intercept form

Answer:

<h3>The given set of polynomials f(x) and g(x) are closed under subtraction.</h3>

Step-by-step explanation:

Given that the functions f ad g are defined by

$f(x)=7x^3-3x^2-x+14$ and $g(x)=2x^3+2x+5$ respectively.

<h3>To show that the set of polynomials is closed under subtraction :</h3>

Now subtract the given polynomials

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

$=7x^3-3x^2-x+14-(2x^3+2x+5)$

$=7x^3-3x^2-x+14-2x^3-2x-5$

$=5x^3-3x^2-3x+9$

∴ $f(x)-g(x)=5x^3-3x^2-3x+9$

When subtracting the polynomials the variables and their exponents remains same only variation in their coefficients.

<h3>Hence the given polynomials f(x) and g(x) are closed under subtraction.</h3>

∴ $f(x)-g(x)=5x^3-3x^2-3x+9$ are closed under subtraction,

Hence showed.

A map of a rectangular park has a length of 4 inches and a width of 6 inches. It uses a scale of 1 inch for every 30 miles. What

e-lub [12.9K]

Answer:

Actual area = 21600 Sq.miles

Step-by-step explanation:

We are given;

length; L = 4 inches

Width; W = 6 inches

The scale of the map; 1 inch for every 30 miles i.e. 1 : 30

Since the scale is 1:30, let's find the find the actual dimensions and then the actual area

For the Length,

Since 1 inch represents 30 miles,

Then, 4 inches = (4 × 30)/1 = 120 miles

For the width;

Since 1 inch represents 30 miles,

Then,6 inches = (6 × 30)/1 = 180 miles

Therefore, the actual dimensions are 120 miles and 180 miles

Now, formula for area of rectangle = length × width

Thus;

Actual area = 120 × 180

Actual area = 21600 Sq.miles
