Answer these two please!

For the first question,

Square-root 5 is NOT a rational number.

It’s irrational because, in decimal form, the number goes on forever and has no repeating numbers in decimal form.

Question 2

Pi is NOT rational.
Pi goes on forever and doesn’t repeat.

Find the equation of a line parallel to y = x – 3 that contains the point (-2, 1).<br> Yeah

SashulF [63]

Answer:

The equation of a line parallel to y = x - 3 that contains the point (-2, 1) is:

$y = x + 3$

The graph of both the parallel equation is shown below to make you further understand the concept.

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

$m$ is the slope

$b$ is the y-intercept

Given the equation

$y = x - 3$

comparing with the slope-intercept form of the line equation

Slope m = 1

<u>Important Tip:</u>

As the parallel lines never intersect, therefore, they have the same slopes.

Thus, the slope of the parallel line is also 1.

As the parallel line contains the point (-2, 1).

so substitute m = 1 and (-2, 1) in the slope-intercept form of the line equation to determine the y-intercept of the parallel line

$y = mx+b$

$1 = 1(-2) + b$ ∵ (x, y) = (-2, 1) and m = 1

$1 = -2 + b$

switch sides

$-2+b = 1$

add 2 to both sides

$-2 + b + 2 = 1 + 2$

simplify

$b = 3$

Thus, the y-intercept b of the parallel line is: b = 3

now substitute b = 3 and m = 1 in the slope-intercept form of the line equation to determine the equation of the parallel line

$y = mx + b$

$y = (1)x + 3$

$y = x + 3$

Therefore, the equation of a line parallel to y = x - 3 that contains the point (-2, 1) is:

$y = x + 3$

The graph of both the parallel equation is shown below to make you further understand the concept.

From the graph:

The green line represents the equation y = x - 3

The black line represents the parallel equation y = x + 3

It is clear that both lines are parallel.

Polynomial Functions help

Studentka2010 [4]

The key piece of information for these questions is the Fundamental Theorem of Algebra, which states that a degree n polynomial has n complex roots. A complex root can be either real or imaginary.

First question, regarding the polynomial y = x^3 - 3x^2 + 16x - 48:
We know there is one real root, the x-intercept.
Since it's a third degree polynomial, there are three complex roots in total.
Therefore, there is one real root and two imaginary roots.
Answer is B

Second question:
You probably can guess the answer, now that you know the Fundamental Theorem of Alegebra:
There are 3 real zeros, each with multiplicity one, meaning each root only happens once. It's a 5th degree polynomial, so there are a total of 5 roots, implying 2 imaginary roots.

Answer is C) 3 real and 2 imaginary zeroes.

What is a necessary step for constructing perpendicular lines through a point off the line?

mixas84 [53]

Draw arcs on either side of a given point on the line

To construct a line perpendicular to another line through a point on the line:

Measure a length from that point to one edge of the line

Draw two intersecting arcs on either sides of the line

Draw a straight line from the intersecting point of the arcs to the point on the existing line.

The new line drawn is a perpendicular line.

The only step necessary out of the given choices is "Draw arcs on either side of a given point on the line"

Option C is the correct choice

Help out please and thank you

VLD [36.1K]

Answer:

y=-1/4x+1

Step-by-step explanation:

Hi there!

We're given the point (-8,3) and a slope of -1/4

lines are typically written in the formula y=mx+b, where m is the slope and b is the y intercept

as we are already given the slope, we can substitute its value into the equation

substitute -1/4 as m

y=-1/4x+b

now we need to find b

as the equation passes through the point (-8,3),we can use it to solve for b

substitute -8 as x and 3 as y

3=-1/4(-8)+b

multiply

3=2+b

subtract 2 from both sides

1=b

substitute 1 as b

y=-1/4x+1
