Elias’s teacher has given him a rectangle that is 15 feet by 20 feet. She has asked him to create a new rectangle using a scale

Vika [28.1K]

Answer:

Yes

Step-by-step explanation:

Because for every 8 feet of the original rectangles, it will be 3 feet on the scale model, therefore it is reducing.

What is the difference of the polynomials? (Ă˘â‚¬""2x3y2 4x2y3 Ă˘â‚¬"" 3xy4) Ă˘â‚¬"" (6x4y Ă˘â‚¬"" 5x2y3 Ă˘â‚¬"" y5) Ă˘â‚¬""6x4y

Polynomial-An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable. The difference between the given polynomials is

$=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5$

Given-

We have given two function of variable <em>x </em>and <em>y</em>

$(-2x^3y^2 + 4x^2y^3-3xy^4)$

$(6x^4y-5x^2y^3-y^5)$

<h3>Polynomial</h3>

An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable.

Now we have to subtract the two equations to find the difference,

$(-2x^3y^2 + 4x^2y^3-3xy^4)-(6x^4y-5x^2y^3-y^5)$

Multiply the sign into the bracket to open the bracket and further solution,

$=-2x^3y^2 + 4x^2y^3-3xy^4-6x^4y+5x^2y^3+y^5$

Arrange the similar terms in the same groups,

$=-2x^3y^2 + (4x^2y^3+5x^2y)-3xy^4-6x^4y+y^5$ $=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5$

Hence, the difference between the given polynomials is $=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5$

What is the equation of a line with a slope of −4 and a point (−2, 5) on the line? Express the equation in the form

Alja [10]

Answer:

y = - 4x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and c the y- intercept )

Here m = - 4, thus

y = - 4x + b ← is the partial equation

To find b substitute (- 2, 5) into the partial equation

5 = 8 + b ⇒ b = 5 - 8 = - 3

y = - 4x - 3 ← equation of line
