Each statement describes a transformation of the graph of f(x) = x. Which statement correctly describes the graph of g(x) if g(x) = f(6x)?
Answer: C. It is the graph of f(x) shrunk horizontally by a factor of 6.
Step-by-step explanation:
When we multiply a function’s input by a positive constant, we get a function whose graph is stretched or compressed horizontally in relation to the graph of the original function. If the constant is between 0 and 1, we get a horizontal stretch; if the constant is greater than 1, we get a horizontal compression of the function.

4. A line passes through (2, -1) and (8,4).
a. Write an equation for the line in point-slope form.
b. Rewrite the equation in standard form using integers.
Answer:
a) Equation of the line [tex]y +1 = \frac{5}{6} (x - 2)[/tex]
b) Equation of the line y + 1 = 0.833 ( x-2)
Step-by-step explanation:
Explanation:-
Given points are ( 2,-1) and (8 ,4)
Slope of the line
[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
[tex]m = \frac{4- (-1) }{8-2 } = \frac{5}{6}[/tex]
Point - slope form
y - y₁ = m ( x - x₁)
y - (-1) = 5 /6 ( x-2)
6 ( y +1) = 5 (x -2)
a) Equation of the line [tex]y +1 = \frac{5}{6} (x - 2)[/tex]
b) Equation of the line y + 1 = 0.833 ( x-2)

SM=3x−4, and RN=9x−20. Find the value of x
Answer:
Option (A).
Step-by-step explanation:
Given question is incomplete; find the complete question with the attachment.
In the triangle NRL,
Points P, S and M are the midpoints of the sides NR, RL and LN respectively.
Sides SM = (3x - 4), NR = (9x - 20)
By the theorem of midpoints in a triangle,
SM = [tex]\frac{1}{2}\text{NR}[/tex]
(3x - 4) = [tex]\frac{1}{2}(9x-20)[/tex]
6x - 8 = 9x - 20
9x - 6x = 20 - 8
3x = 12
x = 4
Therefore, Option (A) will be the answer.
The value of x is equal t 4
Data;
midpoint = SM = 3x - 4Length of line = 9x - 20Midpoint of a LineThe midpoint of a line is half the distance of the line.
Since the length of the line is RN and midpoint of the line is SM.
[tex]SM = \frac{1}{2} RN[/tex]
Let's substitute the values into the equation
[tex]SM = \frac{1}{2} NR\\3x - 4 = \frac{1}{2}(9x- 20)\\ 3x - 4 = \frac{1}{2} (9x - 20)\\2(3x - 4) = 9x - 20\\6x - 8 = 9x - 20\\9x-6x = 20 - 8 \\3x = 12\\\frac{3x}{3} = \frac{12}{3} \\x = 4[/tex]
The value of x is equal t 4

Since domain of any function is the set of all possible input values of the function,
Therefore, Domain of the function is,
Domain : x ≤ 0 Or (-∞, 0]
And range of the function is the set of all possible output values (y-values) of the function.
Therefore, Range of the function will be,
Range : y ≤ 0 Or (-∞, 0]
Therefore, Domain and range of this function is same.

After Mia gave 1/4 of her milk to Dante, Dante had twice the amount of milk as Mia. What was the ratio of the amount of milk Mia had to the amount of milk Dante had at first?
Answer:
4:5
Step-by-step explanation:
You start with the equation:
2(3/4m)=D+1/4m
Simplify it to solve:
5/4m=D
The ratio of the amount of milk Mia had to the amount of milk Dante had at first = 4 : 5
What is ratio?"It is the comparison of two quantities of the same kind."
What is an equation?"It is a mathematical statement which consists of equal symbol between two mathematical statements."
For given question,
Let 'x' be the initial amount of milk Mia had and 'y' be the initial amount of milk Dante had.
After Mia gave 1/4 of her milk to Dante, Dante had twice the amount of milk as Mia.
We write above statement inn equation form as,
[tex]2(\frac{3}{4} x)=(y+\frac{1}{4} x)[/tex]
We simplify above equation to find the ratio of the amount of milk Mia had to the amount of milk Dante had at first.
[tex]\Rightarrow 2(\frac{3}{4} x)=(y+\frac{1}{4} x)\\\\\Rightarrow \frac{6}{4}x- \frac{1}{4} x=y\\\\\Rightarrow \frac{5}{4}x=y\\\\ \Rightarrow \frac{x}{y} =\frac{4}{5}\\\\ \Rightarrow x:y=4:5[/tex]
Therefore, the ratio of the amount of milk Mia had to the amount of milk Dante had at first = 4 : 5

Write the equation of a circle centered at the
point P(-4,-6) and passing through the point
R(2,2).
Answer:
[tex](x+4)^2+(y+6)^2=100[/tex]
Step-by-step explanation:
Given a circle centred at the point P(-4,-6) and passing through the point
R(2,2).
To find its equation, we follow these steps.
Step 1: Determine its radius, r using the distance formula
For point P(-4,-6) and R(2,2)
[tex]\text{Distance Formula=}\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\text{Radius=}\sqrt{(2-(-4))^2+(2-(-6))^2} \\=\sqrt{(2+4))^2+(2+6)^2}\\=\sqrt{6^2+8^2}\\=\sqrt{100}\\Radius=10[/tex]
Step 2: Determine the equation
The general form of the equation of a circle passing through point (h,k) with a radius of r is given as: [tex](x-h)^2+(y-k)^2=r^2[/tex]
Centre,(h,k)=P(-4,-6)
r=10
Therefore, the equation of the circle is:
[tex](x-(-4))^2+(y-(-6))^2=10^2\\\\(x+4)^2+(y+6)^2=100[/tex]

can anyone rewrite the quadratic function in standard form?
Answer:
y = -2(x-2) (x+8)
Step-by-step explanation:
got you bro
Answer:
y = -2x² -12x + 32.
Step-by-step explanation:
Recall that a quadratic equation in standard form is:
y = ax² + bx + c.
To rewrite the equation in standard form, you will need to FOIL and distribute the -2. This can be done by:
y = -2(x-2)(x+8)
FOIL the factored part of the equation. Ignore the '-2' for now.
y = -2 (x² +6x -16)
Now, multiply the '-2' with all of the terms:
y = -2x² -12x + 32.
This is your equation in standard form!
