Classify by degree of polynomial:<br> 3x3 - 6x
e-lub [12.9K]

Answer:

polynomial of degree 3

Step-by-step explanation:

Given

3x³ - 6x

The degree of a polynomial is given by the exponent of the term with the largest exponent.

In this case 3x³ has exponent 3 and - 6x has exponent 1

Thus this is a polynomial of degree 3

artcher [175]

Answer:

91p^{1+3q^{2r}}q^{2r^3}

Step-by-step explanation:

  (-7pq^2r^3) * (-13p^3q^2r)

= 91p^{1+3q^{2r} }*q^{2r^{3} }

= 91p^{1+3q^{2r}}q^{2r^3}

Find the equation of a line, in slope-intercept fotm of a line that passes through the point (9,2) and is perpendicular to the l
cricket20 [7]

Considering the definition of perpendicular line, the equation of of perpendicular line is y= -\frac{1}{2}x + \frac{13}{2}.

<h3>Linear equation</h3>

A linear equation o line can be expressed in the form y = mx + b.

where

x and y are coordinates of a point.

m is the slope.

b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

<h3>Perpendicular line</h3>

Perpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.

<h3>Equation of perpendicular line in this case</h3>

In this case, the line is 2x-y=8. Expressed in the form y = mx + b, you get:

-y=8 - 2x

y= (-2x +8)÷ (-1)

y= 2x -8

If you multiply the slopes of two perpendicular lines, you get –1. In this case, the line has a slope of 2. So:

2× slope perpendicular line= -1

slope perpendicular line= (-1)÷ (2)

<u><em>slope perpendicular line= -</em></u>\frac{1}{2}

So, the perpendicular line has a form of: y= -\frac{1}{2}x + b

The line passes through the point (9, 2). Replacing in the expression for perpendicular line:

2= (-\frac{1}{2})× 9 + b

2=  -\frac{9}{2} + b

2+ \frac{9}{2}= b

<u><em /></u>\frac{13}{2}<u><em>= b</em></u>

Finally, the equation of of perpendicular line is y= -\frac{1}{2}x + \frac{13}{2}.
