Consider an example of an apartment: The number of bedrooms, bathrooms, and the floor of an apartment determines its price. Which is the dependent variable in this example
Answer: The price of the apartment.
Step-by-step explanation:
We know that for a given apartment, the number of bedrooms, bathrooms, and floor determines the price.
Then we could define the variables:
x = number of bedrooms.
y = number of bathrooms
z = floor.
And define the price of the apartment as a function of these variables:
p(x, y, z) = price
Then the independent variables are x, y, and z.
And the dependent variable (this is, the variable that changes in response to the changes in the independent variables) will be the price of the apartment.
Using function concepts, it is found that the dependent variable in this example is the price.
The standard format of a function is: [tex]y = f(x)[/tex].In which each value of y is a function of one value of x, and thus, x is the independent variable and y is the dependent variable.In this problem, price depends of the number of bedrooms, bathrooms, and the floor of an apartment, hence, the function is:
[tex]p = f(be, ba, fl)[/tex]
Which means that the dependent variable is the price.

Point A, located at (-11, - 7) on the coordinate plane, is reflected over the x-axis to form point B. Then point B is reflected over the y-axis to form point C. What are the coordinates of points B and C?
Answer:
Answer: B(-11,7) C(11,7)
Step-by-step explanation:
Reflections In The Coordinate Plane
Reflect over the x-axis:When we reflect a point over the x-axis, the x-coordinate remains the same, but the y-coordinate is mapped to its opposite.
The reflection of the point (x,y) over the x-axis is the point (x,-y).
Reflect over the y-axis:When reflecting a point over the y-axis, the y-coordinate remains the same, but the x-coordinate is mapped to its opposite (its sign is changed).
The reflection of the point (x,y) across the y-axis is the point (-x,y).
Point A is at (-11,-7). When reflected over the x-axis, it maps to Point B located at B(-11,7).
Point B is now reflected over the y-axis and maps to C(11,7).
Answer: B(-11,7) C(11,7)

Find an equation of the line with the given y-intercept and slope m.
10, m= 5
The equation of the line is
(Type your answer in slope-intercept form.)
Answer:
y = 5x + 10
Step-by-step explanation:
Use formula: y = mx + b
1. Since m = 5, plug it into where m is
2. 10 has no variable so it's b ( the y-intercept)

Answer:
a > 12
Step-by-step explanation:
To ride the go karts you need to be OVER 12 years old. We are going to use < and > because you can't be 12 and younger. The hint is OVER because this essentially means that the variable a HAS to be bigger than 12. Thus is why the ineuality is a > 12.

Answer:
-46
Step-by-step explanation:
hope this helps ;)
Answer:
Pemdas makes it -46
Step-by-step explanation:
since this is only addition and subtraction it doesn't matter really what order you do it in
2+2=4
-90+40=-50
4+-50=-46
this is thanks to the Commutative property of addition which states that "Changing the order of addends does not change the sum."

What is the diameter of the inscribe circle of the triangle?
============================================
Work Shown:
The two angle bisectors intersect to form the incenter. The incenter is the center of the inscribed circle (aka "incircle"). This circle is the largest possible, but is completely inside the triangle. No portions of the circle spill outside the triangle.
The two segments marked with lengths x+8 and 2x-5 are two radii of the incircle. This is because the sides of the triangle are tangent to the incircle.
Since all radii are the same length, we can set those expressions equal to one another and solve for x
x+8 = 2x-5
x-2x = -5-8
-x = -13
x = 13
This x value then leads to
x+8 = 13+8 = 212x-5 = 2*13-5 = 26-5 = 21Both radii are 21 units long, which helps confirm we have the proper x value. We double the length of the radius ot get the diameter.
So the diameter of the incircle is 2*21 = 42 units long.

Solve, showing and explaining all steps in the process. 7(y + 2) – (2y – 5) = 41
Answer:
Step-by-step explanation:
Remove parentheses.
7(y+2)-2y+5=41
2 Expand.
7y+14-2y+5=41
3 Simplify 7y+14-2y+5 to 5y+19.
5y+19=41
4 Subtract 19 from both sides.
5y=41-19
5 Simplify 41-19 to 22
5y=22
6 Divide both sides by 5.
y= 22/5
Answer:
y=6.4
Step-by-step explanation:
distribute:
7y+14-2y-5=41
then combine like terms:
5y+9=41
subtract 9 from both sides:
5y=32
divide 5 by both sides:
y=6.4
