What is an equation of the line that passes through the point (8,0) and is parallel to the line x-4y=20?
Answer:
y= 1/4 (x -8)
Step-by-step explanation:
x -4y= 20
-4y= -x + 20
y= 1/4 × -5
y - y1 = m (x - x1)
y - 0 = 1/4 (x -8)
y= 1/4 (x -8)

f (x) = x +11. Find the inverse of f(x).
O A. f-1(2) = x3 + 11
O B. f-'(x) = (x + 11)3
O c. f-1(x) = 23 – 11
O D. f-1(x) = (2x – 11)3
Answer:
y = x - 11
Step-by-step explanation:
f (x) = x + 11
y = x + 11

Step-by-step explanation:
Find the missing side of the length, s. I need help!
Answer:
s = 12
Step-by-step explanation:
Since the triangles are similar then corresponding sides are in proportion, that is
[tex]\frac{AB}{XY}[/tex] = [tex]\frac{AC}{XZ}[/tex] , substitute values
[tex]\frac{6}{9}[/tex] = [tex]\frac{8}{s}[/tex] ( cross- multiply )
6s = 72 ( divide both sides by 6 )
s = 12
A quadratic function y = f(x) is plotted on a graph and the vertex of
the resulting parabola is (3, -5). What is the vertex of the function
defined as g(x) = f(-x) + 3?
Answer:
the vertex is (0,3)
Step-by-step explanation:
using vertex form: y=a(x-h)^2+k you can find the vertex
h: the horizontal <----------->
and
k: the vertical |
so, there is no h, but there is a k, which is 3, so the answer is (0,3) I believe

What is an equation of the line that passes through the point (-4,-6) and is
perpendicular to the line 2c – y = 6?
Answer:
y = -1/2c - 8
Step-by-step explanation:
2c - y = 6
2c -6 = y
Slope: 2. Slope of the perpendicular line: -1/2
Point (-4,-6)
y-intercept = -6 - (-1/2)(-4)
b = -6 -2 = -8
The equation of the line that passes through the point [tex](-4,-6)[/tex] and is
perpendicular to the line [tex]2c - y = 6[/tex] is [tex]2x_{2} -y_{2} +2=0[/tex].
What is equation of the line ?Equation of the line: The general equation of a straight line is [tex]y = mx + c[/tex]. This variable [tex]'c'[/tex] is called the intercept on the [tex]y-axis[/tex]. And [tex]y = c[/tex] is the value where the line cuts the [tex]y-axis[/tex].
Here,
[tex]m=[/tex] the gradient,
[tex]c=[/tex] the intercept on the y-axis
We have,
An equation of the line that passes through the point [tex](-4,-6)[/tex] and is
perpendicular to the line [tex]2c - y = 6[/tex] .
So,
Line [tex]2c - y = 6[/tex]
[tex]2c - y = 6[/tex]
⇒ [tex]y=2c-6[/tex]
and [tex]y = mx + c[/tex]
On comparing above two equations
[tex]m=2[/tex]
and Slope [tex]=-\frac{1}{m}[/tex]
So, Slope [tex]=-\frac{1}{2}[/tex]
Now,
Slope of the equation [tex](m)=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Slope of required equation [tex]=\frac{-1}{Slope \ of \ 2c-y=6}[/tex]
[tex]=\frac{-1}{\frac{(-1)}{2} }=2[/tex]
Now,
Equation of line with slope [tex]2[/tex] and passing through point [tex](-4,-6)[/tex] ,
Slope of the equation [tex](m)=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
[tex]2=\frac{y_{2} -(-6) }{x_{2} -(-4) }[/tex]
[tex]2x_{2} +8=y_{2} +6[/tex]
[tex]2x_{2} -y_{2} +2=0[/tex]
So, the equation of the line is [tex]2x_{2} -y_{2} +2=0[/tex] .
Hence, we can say that the equation of the line that passes through the point [tex](-4,-6)[/tex] and is perpendicular to the line [tex]2c - y = 6[/tex] is [tex]2x_{2} -y_{2} +2=0[/tex].

Express (3/5+ 3)^2
as a trinomial in simplest form.
Hey there!
Fun fact:
• MONOMIAL contains ONE term because MONO- means 1
• BINOMIAL contains TWO terms because BI- means 2
• TRINOMIAL contains THREE terms.. because TRI- means 3.
• POLYNOMINAL contains FOUR or MORE terms because POLY- means 4 or more
ANSWERING YOUR QUESTION
(3/5x + 3)^2
= (3/5x)(3/5x) + (3/5x)(3) + (3/5x)(3) + 3(3)
• 3/5x(3/5x) = 9/25x
• 3/5x(3) = 9/5x
• 3(3) = 9
= 9/25^2 + 9/5x + 9/5x + 9
• COMBINE the LIKE TERMS
= (9/25)x^2 + 18/5x + 9
Therefore, your answer is:
“9/25x^2 + 18/5x + 9”

-0.48x+0.28=4.6
-0.2x=4.6
x=-23
Answer:
it’s -0.2x =4.6
Step-by-step explanation:
X = -23 is the answer for the equation but
your asking for what the number is before the x right
it’s -0.2x =4.6
than multiple both sides by 10
divide both sides by -2
simplify
X=-23

Answer:
10 neutrons
Step-by-step explanation:
no.of neutrons = atomic mass - Atomic number
no.of neutrons= 22-12

how to use solution of an inequality in the real world?
They seek to describe the way nature flows. Many of the simpler equations also describe financial concepts, like exponential growth. Exponential growth can describe the cultivation of microorganisms as well.
Addition and substraction is used in shopping.
Much of mathematics are also used in programming in order to make smart software.
You basically used equations everyday without even notice. Like when you have to calculate “How many dollars does the sum of your grocery stuffs equal to?”. Or a more complicated situation, if you need to be in the meeting at 9:30am, the travel distance is 10km and you can only leave after 8:30am, your driving speed should equal “x” km/h.”
Inequalities are used for comparison. “He is taller than me.” or “The iPhone with larger memory capacity is more expensive.”. A more complicated example is also with calculating your driving speed. “Now if there is expected traffic jam for 2km. You get out of the traffic jam at 9:00am, you have to drive faster than
“x” km/h to compensate for your loss time.”
Just some simple examples. There are a lots more out there, just look around.
