Coplanar lines are referred to as parallel lines because they may be extended indefinitely without ever intersecting. || is the sign meaning "parallel to." If two lines are drawn, they don't have to be parallel, and a third line runs across them as seen in the diagram below. We may obtain eight distinct angles by drawing two parallel lines, and then drawing a transverse line through them.
Four pairs of matching angles will be created from all eight angles. One of the pairings is represented by angles F and B in the preceding diagram. If the two lines are parallel, corresponding angles are congruent.

Write a polynomial function f of least degree that has rational coefficients, a leading
coefficient of 1, and the given zeros of -1, 2, and -3i. Show all work.
The least degree polynomial function with rational coefficients and the given zeros, -1, 2 and 3i is f(x) =[tex]x^{2} -x -2(\sqrt{x} -9)[/tex]
What do we mean by polynomial function?
A polynomial function is one that involves only non-negative integer powers or positive integer exponents of a variable in an equation such as the quadratic equation, cubic equation, and so on.
For example, 2x+5 is a polynomial with an exponent of one.
So given zeroes are -1 , 2 and 3i
We have,
x = -1
x +1 =0
Similarly for 2
x = 2
x -2 = 0
Again, For 3i
We have, x = 3i
Rewrite as x = [tex]\sqrt{-9}[/tex]
For easy calculation, squaring on both sides
[tex]x^{2} = -9[/tex]
[tex]x^{2} +9[/tex] =0
So, the polynomial has the function:
(x + 1)(x - 2) ([tex]\sqrt{x} -9[/tex])
[tex]x^{2} - 2x +x -2 (\sqrt{x} -9)\\x^{2} -x -2(\sqrt{x} -9)\\[/tex]
Therefore, the least degree polynomial function with rational coefficients and the given zeros, -1, 2 and 3i is f(x) =[tex]x^{2} -x -2(\sqrt{x} -9)[/tex].

The equation of the line that passes through point (8,-1) and perpendicular to 8y = x - 16 is f(x) = -8x + 63.
What is the equation of line that passes through the given points and is perpendicular to the given line?Given the data in the question;
Equation of line: 8y = x - 16Point: (8,-1)First we determine the slope of the initial line using the slope intercept-form. y = mx + b
8y = x - 16
y = (1/8)x - 2
Compared with the slope intercept form,
Slope m = 1/8
Now, for the equation of line perpendicular to the initial line, its slope must be a negative reciprocal of the initial slope.
Hence, slope of the perpendicular line is;
Slope m = -1/1/8 = -8
To find the equation of the perpendicular line, we use the point slope formula.
y - y₁ = m( x - x₁ )
Plug in the slope m ( -8) and point (8,-1).
y - (-1) = (-8)( x - 8 )
y+1 = -8x + 64
y = -8x + 64 - 1
y = -8x + 63
Therefore, the equation of the perpendicular line is y = 8x + 63

Step-by-step explanation:
your teacher gave you the formula, the values, even did the tricky part by telling you that 63 months are 5.25 years.
all you need to do is put everything into the formula and calculate.
so, calm down, breathe and just use common sense :
1.
after 2 years (means t = 2) :
2000 × (1.025)^(2×2) = 2000 × (1.025)⁴ =
= 2000 × 1.103812890625 =
= $2,207.62578125 ≈ $2,207.63
as rounding to the nearest cent means rounding to 2 positions after the decimal point.
2.
after 63 months = 5.25 years (t = 5.25)
2000 × (1.025)^(2×5.25) = 2000 × (1.025)^10.5 =
= 2000 × 1.295986825... =
= $2,591.973651... ≈ $2,591.97
3.
$2,000
because, even t = 0 we have
2000 × (1.025)^(2×0) = 2000 × (1.025)⁰ = 2000 × 1 =
= $2,000

find the x and y intercepts of 2x-5y=12 (write all answers as points)
Here, we want to find the x and y intercepts of the given line
We start by writing the equation of the line in the standard form
The standard form is;
[tex]y\text{ = mx + b}[/tex]where m is the slope and b is the y-intercept
We have the equation re-written as;
[tex]\begin{gathered} 5y\text{ = 2x - 12} \\ y\text{ = }\frac{2}{5}x\text{ - }\frac{12}{5} \end{gathered}[/tex]As we can see, we have the y-intercept at the point y = -12/5
The coordinate form at this point is (0,-12/5)
To find the x-intercept, we simply set y to zero
This is;
[tex]\begin{gathered} 0\text{ = }\frac{2}{5}x\text{ - }\frac{12}{5} \\ \\ \frac{2}{5}x\text{ = }\frac{12}{5} \\ \\ 2x\text{ = 12} \\ x\text{ = }\frac{12}{2} \\ x\text{ = 6} \end{gathered}[/tex]The x-intercept is thus (6,0)
I need it in slope intercept form and it has to be PERPENDICULAR to the equation it gives.
The equation of the line in slope intercept form perpendicular to 6x - 2y = 12 and has the same y-intercept is y = - 1 / 3 x - 6
How to find equation in slope intercept form?The equation in slope intercept form can be represented as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the equation of the line is perpendicular to 6x - 2y = 12 and have the same y-intercept.
Hence, perpendicular lines follows the rule below:
m₁m₂ = -1
6x - 2y = 12
6x - 12 = 2y
y = 3x - 6
Hence,
3m₂ = -1
m₂ = - 1 / 3
Therefore, the slope of the line is - 1 / 3.
The y-intercept is -6
Therefore,
the equation of the line is y = - 1 / 3 x - 6

The equation of the line will be y = 2x + 1.
What do we mean by the equation of the line?The set of points that make up a line in a coordinate system is represented algebraically by a line's equation. An equation of a line is an algebraic expression that represents the many points that together make up a line in the coordinate axis as a set of variables, x, and y.So, the equation of the line:
The equation is parallel to y = 2x -2 and the slopes equation is y = mx + b where m is the slope.So, the slope is 2.Then, y = 2x + b
Now, substitute x = 1 and y = 3 in the above equation to find b:
y = 2x + b3 = 2(1) + bb = 3 - 2b = 1So, the equation of the line will be: y = 2x + 1

The equation of the line that passes through the point (-4,2) and the parallel to the line y = 1/4x + 1 is y = (1/4)x+3
The equation of the line parallel to the line is
y = 1/4 x +1
The slope intercept form is
y = mx + b
Where m is the slope of the line and b is the y intercept
By comparing the given equation and slope intercept form of the line
The slope of the line is m = 1/4
Then the point slope form is
[tex](y-y_1)= m(x-x_1)[/tex]
The line is passing through the point (-4,2)
Substitute the values in the equation
(y-2) = 1/4(x-(-4))
y-2 = 1/4(x+4)
y-2 = (1/4)x+1
y = (1/4)x+3

For what values of x is the expression below defined?x+5+ v1 -O A. 5 >x>1B. 5 sxs1C. -5 s x < 1D. 5 > XS-1SUBMIT
The correct range of definition is;
[tex]C;\text{ -5}\leq x<1[/tex]Here, we want to get the range of values of x for which the given expression is defined
The key here is that any value of x that will make us have a negative value inside the root will make the expression undefined as that would give us a non-real root
Now, let us take a look at the options;
a) if x is greater than 1, we will have a negative root on the right, making the expression undefined. This option is wrong
b) This is also wrong; if 5 is less than x, then x might be 6 , which would give a negative root value
c) If -5 is less than x, x could take values of -4, -3, -2 and the root on the right will never be negative. But in cases like this, we have the spectrum upto positive values of x such as 5 which would make the root on the right negative and undefined. This range here is the correct answer
d) Here, 5 is greater than x, so the root on the left can never be negative. For values less than -1, like -6, what we have on the left will be undefined
Due to increased mailing costs, the new rate will cost publishers $50 million; this is 12.5% more than they
paid the previous year. How much did it cost publishers last year? Round to the nearest hundreds.
The amount it will cost the publishers last year is 44.4 million
How to calculate the amount it will cost the publishers?The first step is to write out the parameters
The cost of mailing increased for the last one year
Due to this increase, it will cost the publishers $50 million for this current year
The increase is at the rate of 12.5%
The amount it will cost the publishers last year can be calculated as follows
= 12.5/100
= 0.125 + 1
= 1.125
The next step is to calculate last year cost
last year cost= 50/1.125
