Answer:
f(x) = 0.5x
Step-by-step explanation:
For this problem, we simply have to find the constant of proportionality between x and f(x). In other words, what x is multiplied by to get f(x).
Since this proportion is constant (meaning it doesn't change), all we have to do is divide an f(x) value in the table by its corresponding x value.
p = f(x) / x
p = -2 / -4
p = 1/2 = 0.5
We can show the relationship of x to f(x) with the equation f(x) = px, which can be simplified using the constant of proportionality that we just solved for.
f(x) = 0.5x

What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is (-4x²) (3x⁵) / (2x⁻⁴).
We have the rule for exponents,
xᵃ . xᵇ = xᵃ⁺ᵇ
xᵃ / xᵇ = xᵃ⁻ᵇ
(-4x²) (3x⁵) = (-4 × 3) x²⁺⁵ = -12x⁷
-12x⁷ / 2x⁻⁴ = (-12 / 2) x⁷⁻⁻⁴
= -6x¹¹
Hence the simplification of the expression (-4x²) (3x⁵) / (2x⁻⁴) is -6x¹¹.

How to find the measure of angle 3?Remember that when two lines intercept and 4 angles are formed, the vertical angles (these ones connected only by the vertex) have the same measure.
For example, 2 and 5 are vertical angles in this case.
Angles 6 and 3 also are vertical angles, and if both white lines are parallel, then the measures of angle 1 and 6 will be equal (because both are on the same quadrant) then:

One number is six less than three times another number. If the sum of the numbers is 38, find the numbers.
Answer: Let's call the first number "x" and the second number "y".
From the problem statement, we know that:
x = 3y - 6 (because one number is six less than three times the other number)
x + y = 38 (because the sum of the numbers is 38)
We can substitute the first equation into the second equation to solve for one of the variables:
3y - 6 + y = 38
4y - 6 = 38
4y = 44
y = 11
Now we can substitute this value of y back into the first equation to find the value of x:
x = 3(11) - 6
x = 29
So the two numbers are:
x = 29
y = 11

The rule for the glide reflection that maps △ABC with vertices A(–4, –2), B(–2, 6), and C(4, 4) to △A′B′C′ with vertices A′(–2, –2), B′(0, –10), and C′(6, –8) is T⟨a, b⟩ ∘ Rx-axis where
The ΔABC reflects across x-axis with point a=2 and scale factor of x+2 to form the ΔA'B'C'.
What is reflection?
A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.
The vertices of ΔABC is given as -
A(–4, –2), B(–2, 6), and C(4, 4)
The vertices of ΔA'B'C' is given as -
A′(–2, –2), B′(0, –10), and C′(6, –8)
To find the scale factor of the reflection use the formula -
x + a = x' and y + b = y'
Substitute the values in the equation.
For vertex A and A' -
x1 + a = x1'
-4 + a = -2
a = -2 + 4
a = 2
y1 + b = y1'
-2 + b = -2
b = -2 + 2
b = 0
For vertex B and B' -
x2 + a = x2'
-2 + a = 0
a = 0 + 2
a = 2
y2 + b = y2'
6 + b = -10
b = -10 - 6
b = -16
For vertex C and C' -
x3 + a = x3'
4 + a = 6
a = 6 - 4
a = 2
y3 + b = y3'
4 + b = -8
b = -8 - 4
b = -12
It can be seen that the values of a is constant whereas the values of y varies. This happens due to reflection of coordinates across the x-axis.
Therefore, the reflection happens across the x axis.

5. Jenna is making
bracelets.
She needs 7
inches of string for each
bracelet. She has a spool
with 16 feet of string. How
many bracelets can Jenna
make?
Answer:
Step-by-step explanation:
Each bracelet need 7 inches of string. Jenna has a total of 16 feet of string.
Divide the total amount of string by the number of inches needed for each bracelet.
Step 1: Convert 16 feet into inches. 12 inches = 1 foot
16 feet x (12 inches/1 foot) = 192 inches
This is the total inches of string.
Note that feet and foot units cancel and you are left with inches.
Step 2: Find the number of bracelets that can be made. Use the answer from step 1. Each bracelet needs 7 inches of string.
Total inches of string / 7 inches of string for each bracelet
192 inches / 7 inches = 27.4

The list below gives the location of 3 friends who are scuba diving together. Mallory is exploring at an elevation of -25 feet. Jacob is standing on the boat, at an elevation of 15 feet. Eva just jumped in and is 5 feet below the surface of the water.
Which inequality correctly compares the distance of the scuba divers from the surface of the water?
Which one of these?
1- Eva > Mallory
2- Mallory < Jacob
3- Jacob < Eva
4- Mallory > Eva
Mallory is further from the surface than Eva. So, Mallory > Eva. Therefore, option D is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, Mallory is exploring at an elevation of -25 feet.
So, distance between Mallory and the surface of water is 25 feet
Jacob is standing on the boat, at an elevation of 15 feet.
Distance between Jacob and the surface of water is 15 feet
Eva just jumped in and is 5 feet below the surface of the water.
Distance between Eva and the surface of water is 5 feet
In this case, the person closest to the surface is Eva, who is 5 feet from the surface.
So, the inequality is Mallory > Eva
Therefore, option D is the correct answer.

What are the 2D shapes?The plane forms that can be sketched on a flat (or plane) surface or a piece of paper are known as 2D shapes. Every 2D shape has different attributes, like area and perimeter. Some of the two-dimensional objects have sides and corners, while others have curved edges.
Given two pathways,
circular and square, and the circular pathway is inscribed inside of a square pathway,
area of circular pathway = 768 square feet
area of circle = π/4*d²
where d is the diameter
768 = π/4*d²
768*4 = πd² (π = 3)
3072/3 = d²
d = √1024
d = 32 feet
since the circle is inscribed in a square the length of a side of square is equal to the diameter of the circle,
d = a = 32 feet
to find the perimeter of the square path,
perimeter of square = 4a
perimeter of square = 4*32

How to determine the solution to the systemFrom the question, we have the following parameters that can be used in our computation:
2x−3y=12
−12y+8x=48
divide the first equation by 2
So, we have
x - 1.5y = 6
This gives
x = 6y + 1.5
By substitution, the second equation becomes
-12y + 8 (6y + 1.5) = 48
So, we have
-12y + 48y + 12 = 48
Evaluate
36y = 36

graph the equation y=2/3x-1 iready quiz graph linear equations
Answer: To graph the equation y = 2/3x - 1, we can start by finding some points that satisfy the equation.
We can pick any value for x and substitute it into the equation to find the corresponding y-value.
For example:
When x = 0, y = (2/3)(0) - 1 = -1
When x = 1, y = (2/3)(1) - 1 = -1/3
When x = 2, y = (2/3)(2) - 1 = 1/3
When x = 3, y = (2/3)(3) - 1 = 2/3
We can plot these points on a coordinate plane and then connect them with a straight line to graph the equation.
The graph will be a line that passes through the points (0, -1), (1, -1/3), (2, 1/3), and (3, 2/3).
