olga55 [171]

Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign. The given option the option A matches correctly with the above polynomial equation which is,

$-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4$

Hence the option A is the correct option.

<h3>Given information-</h3>

The given polynomial equation in the problem is,

$8x^2y^2-\dfrac{3x^3y}{2}+4x^4-7xy^3$

<h3>Polynomial equation </h3>

Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign.

In the above polynomial equation the variable are x and y and the highest power of the variable x is four and highest power of the variable y is three.

Arrange the polynomial equation in the power of the variable x. Thus,

$4x^4-\dfrac{3x^3y}{2}+8x^2y^2-7xy^3$

Arrange the polynomial equation in the power of the variable y. Thus,

$-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4$

From the given option the option A matches correctly with the above polynomial equation which is,

$-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4$

Thus the option A is the correct option.

The formula y - y1 = m(x - x1) is the point-slope form of the equation of a line where m is the slope of the line and (x, y) and

a_sh-v [17]

Answer:

The slope of a line that includes the points (4, -2) and (5, 0) is 2

Step-by-step explanation:

You know that the formula y - y1 = m(x - x1) is the point-slope form of the equation of a line where m is the slope of a line.

The line must include the points (4, -2) and (5, 0). So, being:

(x,y)= (4,-2)
(x1,y1)= (5, 0)

and replacing in the point-slope form of the equation of a line:

-2-0=m(4-5)

You solve the equation for m and get:

-2=m*(-1)

$m=\frac{-2}{-1}$

m=2

The slope of a line that includes the points (4, -2) and (5, 0) is 2

What is the solution to -55+q=7 A. a=-62 B. q=62 C. q=42 D. q=-42

Scorpion4ik [409]

Answer:

C, as q = 62.

Step-by-step explanation:

When you have an equation, your goal is to get the letter you are solving for alone. To do this, you employ a simple rule: what you do to one side of the equals sign, you must do the other.

To isolate q in -55 + q = 7, you must add 55 to the left side. q is now alone. However, because we added 55 to the left side, we must also do it to the right! 7 + 55 = 62, so the new right side is 62. Hence, we get to this:

q = 62

The answer is now in plain sight!
