Answer:
I can find all the x-values in the domain of the function f(x)=4:
Domain = (−∞, ∞), {x | x∈R}
Here’s the range if you need it:
Range: {4}
Hope this helps! :)
The answer is Range: {4} or, x is a member of the real numbers and that it can be anything from negative infinity to positive infinity.
What is number?A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.
Here, we have,
f (x) =4
now,
we can find all the x-values in the domain of the function f(x)=4:
Domain = (−∞, ∞), {x | x∈R}
Here’s the range if you need it:
Range: {4}
There are x’s in the equation.
It’s actually all numbers are x’s because anything you put into the function f(x)=4, y will always equal 4.
So the value of x in f(x)=4 is all numbers.
To be more specific, all real numbers.
That’s why I put (−∞, ∞), {x | x∈R} because x is a member of the real numbers and that it can be anything from negative infinity to positive infinity.

Answer:
Train B is traveling faster.
Step-by-step explanation:
To find which train is faster, divide the distance the train traveled by the elapsed time for each train:
Train A:
Distance traveled is 12.5 meters.
Elapsed time is 1 second.
12.5 ÷ 1 = 12.5
Train A travels 12.5 meters per second.
Train B:
Distance traveled is 100 meters.
Elapsed time is 4 seconds.
100 ÷ 4 = 25
Train B travels 25 meters per second.
25 is greater than 12.5, so train B travels faster.
Find the slope of the line. Write your answers in simplest form
Answer:
-3/5
Step-by-step explanation:
using the picture and the rise over run method, you can see that from the coordinate farthest to the right, you move 3 spaces up (positive), and 5 spaces to the left (negative), which gives you your answer of -3/5.
You can also use the formula to find the slope:
1) y₂-y₁/x₂-x₁
2) -2-1/1-(-4)
3) -3/5

The graph of y = |x − 3| + 2 is reflected across the x-axis and then translated down 2 units. What is an equation of the transformed graph?
Answer:
y=-|x − 3|
Work
y = |x − 3| + 2
-2 -2
y = |x − 3|
add a neg before the absolute value
y=-|x − 3|
Transformation involves changing the position of a graph
The equation of the transformed graph is [tex]\mathbf{y = -|x -3| - 4}[/tex]
The equation is given as:
[tex]\mathbf{y = |x -3| + 2}[/tex]
The rule of reflection across the x-axis is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{y = -|x -3| - 2}[/tex]
The rule of translation 2 units down is:
[tex]\mathbf{(x,y) \to (x,y-2)}[/tex]
So, we have:
[tex]\mathbf{y = -|x -3| - 2 - 2}[/tex]
[tex]\mathbf{y = -|x -3| - 4}[/tex]
Hence, the equation of the transformed graph is [tex]\mathbf{y = -|x -3| - 4}[/tex]

Hi there!
[tex]\large\boxed{\left \{ {{y\geq -x + 3} \atop {y > 2x - 3}} \right.}[/tex]
We can begin by looking at the solid-line pictured in the graph.
Using the slope-formula, we can derive the slope from this line:
[tex]\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }[/tex]
Plug in points from the line:
[tex]m = \frac{0- 3 } { 3 - 0} = -1[/tex]
We can also see that the graph has a y-intercept, or "b" value of 3. The line is a solid line including values above it, which means we must use a "greater than or equal to" symbol. Therefore, the final equation is:
y ≥ -x + 3
The second line is dashed and also has values shaded above its graph. We can use this later to make an equation, but let's solve for the slope for now. Use the same equation as above:
[tex]m = \frac{1-(-3)}{2-0} = 4/2 = 2[/tex]
The graph has a y-intercept at y = -3, so this is the "b" value in its slope-intercept formula.
Use a "greater than" sign (Not equal to... the line is dashed) to write the equation:
y > 2x - 3

x=2.52
Step-by-step explanation:
30.16=17.56+5x
Subtract 17.56 from both sides
12.6=5x
17.56 cancels on the right side
Divide 5 to both sides
5 cancels on right side
12.6/5=2.52

Find the rate of change of the following table.
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The rate of change is measured by the slope of the line in this linear table.
Calculate the slope m using the slope formula
m = [tex]\frac{y_{3}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (3, 2) ← 2 ordered pairs from the table
m = [tex]\frac{2-0}{3+3}[/tex] = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex] ← rate of change

Parellel lines it says 75 degrees and on another line it says 11x-2 what's the answer?
Answer:
x = 7
Step-by-step explanation:
Parallel lines so their the same
11x - 2 = 75
add 2 to both sides
11x = 77
divide both signs with 11
x = 7
Answer:
The answer to the equation below is also 75 degrees. X equals 7
Step-by-step explanation:
Assuming that the lines are parallel, we can confirm that the two angles are corresponding because they are cut by a traversal (corresponding means that they occupy the same relative position). Knowing that the are corresponding use the equation 11x-2= 75 to find x. You are welcome and I hope you get the best grade possible :). Have a nice day!
