Answer:
First, the function:
y = x
Is:
Positive if x > 0
Negative if x < 0
Now, on another hand, the function y = IxI is:
Positive if x < 0
Positive if x > 0.
Then the only part that changes is the negative side of the domain, and the thing that changes is the sign (the change of sign is equivalent to a reflection over the x-axis or the line y = 0".
Then the correct option is:
"All points for x < 0 are reflected over the x-axis"
I suppose that this is option C, the missing one.

You begin painting your house with 10 gallons of paint you purchased at the hardware store. Each gallon of paint covers 400
square feet of surface area. If g is the gallons of paint used for painting x square feet, which type of model would best describe the
relationship between g and x?
A)
linear
B)
radical
quadratic
D)
exponential
Answer:
A) linear
Step-by-step explanation:
Let the gallons of paint be represented by g, and the area by x.
Each gallon of paint covers 400 square feet of surface area.
⇒ x = 400g
So that; when g = 1,
x = 400 square feet
when g = 5,
x = 400 x 5
= 2000 square feet
when g = 10,
x = 400 x 10
= 4000 square feet
The relationship between the variables is linear because g and x increases at a constant rate.
What is the equation of a line that is parallel to the line y = 2x + 7 and passes through the point (–2, 4)?
Group of answer choices
y = 2x + 8
y = −12x − 2
y = 2x + 4
y = −12x + 3
Determine the value of y, if x is-6.
y= |x|+ 6
Answer:
Answer:
y = 12
Step-by-step explanation:
The two bars between x mean absolute value, so all negatives turn into positives because absolute value just means the total distance from zero.
y = |x| +6
y = |-6|+6
y = 6+6
y = 12
Have an amazing day!!!! C:
what is m pqr (3x-5) (x+1)
The value of measure ∠PQR is,
⇒ ∠PQR = 133°
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
In the given figure,
⇒ ∠PQR = (3x - 5)°
⇒ ∠ RQS = (x + 1)°
Now, By the figure we can conclude,
⇒ ∠PQR + ∠ RQS = 180°
Substitute the given values, we get;
⇒ (3x - 5) + (x + 1) = 180
⇒ 4x - 4 = 180
⇒ 4x = 180 + 4
⇒ 4x = 184
⇒ x = 184/4
⇒ x = 46
Thus, The value of measure ∠PQR is,
⇒ ∠PQR = (3x - 5)°
⇒ ∠PQR = (3 × 46 - 5)°
⇒ ∠PQR = (138 - 5)°
⇒ ∠PQR = 133°

Step-by-step explanation:
Because if it can eat 2/5's in 1/2 hours, then if it eats for 1 whole hour or 2/2's it will be able to eat 4/5's of it's own body weight.
Just imagine that one half hour is 1 and if you add two half hours together it makes one complete hour or 2/2. So just multiply it by 2 cause it was eating for two half hours.

A twons populations is 43,425. About 125 people move out of the town each month, 200 people on the average move into town. A nearby town has population of 45,000. it has no one moving in and an average of 150 people moving away every month. In about how many months will the population of the towns be equal? Write an equation that represents this situation and solve.
Answer:
After 7 months months the population of both the town will be equal.
Step-by-step explanation:
Let's assume, the population of both towns will be equal after x number of months.
Every month 125 people move out of the town and 200 people move into the town, where already 43,425 people are living. So, the population of the former town after x months is,
Every month 150 people move out of the town, where already 45,000 people are living. So, the population of the latter town after x months is,
when the population of both of the towns are same,then

Question 1 :In order to convert this equation to Slope-Intercept Form, you must first isolate y.
What is the first step in isolating y?
6x+7y=14
Question 3: Convert to Slope-Intercept Form to graph 3x+5y=10.
Answer:
Step-by-step explanation:
Add -6x to both sides
6x + 7y + − 6x = 14 + − 6x
7y = − 6x + 14
Divide both sides by 7
7y / 7 = − 6x + 14 / 7
y = − 6 / 7x + 2
Answer
y = −6 / 7x + 2

In order to convert 6x+7y=14 equation to Slope-Intercept Form is use the subtraction property of equality to subtract 6x from both sides of the equation
What is Slope-Intercept?One of the four additional techniques for figuring out any straight line's equation is the slope-intercept form. Typically, straight lines are shown as y = mx+c. The x and y variables are said to have a maximum power of unity by this common straight line equation. As a result, x = x1 and y = y1. Additionally, this demonstrates that only linear equations can be solved using the slope-intercept form. You ought to be able to solve linear equations with two variables. The graph of such equations is a straight line, as you should be aware of. Additionally, you need to be confident in your understanding of the y-intercept, x-intercept, and slope properties of linear equations.6x + 7y = 14 to rewrite in the form y = mx + b,
make y the subject of the equation 6x + 7y = 14
7y = -6x + 14
divide both sides by 7
y = (-6/7)x + 2
The slope is -6/7 while the intercept is 2.

PLEASEEE HELP On a coordinate plane, the vertices of triangle ABC are A(−3, 1), B(6, 4), C(2, 5). The vertices are translated 4 units to the right and down 3 units.
1. Write a rule, P(x, y) → P'(x + a, y + b), that represents the translation.
2. What are the coordinates after the translation?
Answer:
A (1,-2) B(10,1) C(6,2)
Step-by-step explanation:
You add 4 to the x value and subtract 3 from the y value to get the answer.
The coordinates of the vertices after the translation are A'(1, -2), B'(10, 1), and C'(6, 2).
How to calculate the coordinates?To represent the given translation, we need to add the same constant amount to the x-coordinate of each vertex and subtract the same constant amount from the y-coordinate of each vertex.
Let's call the constants of translation "a" and "b", respectively. Then the rule P(x, y) → P'(x + a, y - b) represents the translation of a figure where P is any point in the original figure and P' is the corresponding point in the translated figure.
To find the coordinates after the translation, we need to apply the translation rule to each vertex of the triangle.
For vertex A(-3, 1), we add 4 to the x-coordinate and subtract 3 from the y-coordinate, giving us the new coordinates of A': (-3 + 4, 1 - 3) = (1, -2).
For vertex B(6, 4), we add 4 to the x-coordinate and subtract 3 from the y-coordinate, giving us the new coordinates of B': (6 + 4, 4 - 3) = (10, 1).
For vertex C(2, 5), we add 4 to the x-coordinate and subtract 3 from the y-coordinate, giving us the new coordinates of C': (2 + 4, 5 - 3) = (6, 2).
Therefore, the coordinates of the vertices after the translation are A'(1, -2), B'(10, 1), and C'(6, 2).

if you have a pizza that has 24 slices and your friend eats 1/8 of it and you eat 1/3 how much is left
Answer:
13 slices
Step-by-step explanation:
The pizza has 24 slices. To figure out what 1/8 of 24 is, divide 24 by 8. To figure out what 1/3 of 24 is, divide 24 by 3. 1/8 of 24 is 3, and 1/3 of 24 is 8.
3 + 8 = 11 (number of slices eaten)
24 - 11 = 13 (number of slices left)
So if you start at the 8th floor then down 10 floors what dose that mean!!!!!!!
