Answer: C: cubic expression
Step-by-step explanation:
Classify the expression: 5x³ + 2x − 3
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
so
a) By the number of terms is a trinomial, because has three terms
b) By their degree The degree of the polynomial is found by looking at the term with the highest exponent on its variable
The highest exponent is 3 so this is a 3rd degree trinomial
therefore
Is a cubic expression

A farmer wants to construct a rectangular pigpen so only 3 sides of the pen will need to be fenced. If the farmer has 400 ft of fence, whats the maximum area he can enclose?
The dimensions of the rectangular pigpen with the largest possible area are 50 ft×25 ft.
The area and perimeter of a rectangle in the study of differential calculus, specifically in optimization problems are functions of two variables that depending on what is requested in these problems can be objective functions or link functions between the variables.
We use what we know about the perimeter of the rectangle to find a condition equation that expresses the length a in terms of the width b.
P(a, b)=a+2b [Perimeter of the fence of the rectangular pigpen]
p(a, b)=2a+3b [Substitute P(a, b)=100]
100=a+2b
a=100-2b
We must find the largest area. Using the condition equation, find the area as a function of the variable b.
A(a, b)=ab [total area of the rectangular pigpen]
A(a, b)=(100-2b)b [Replace a=100-2b]
A(a, b) = 100b-2b²
Objective function Domain
A(a, b) = 100b-2b²
D={b∈R : b>0} [Domain of the objective function]
To find the extremes of the function we have to look for the critical points of the function and apply the second derivative test.
A(a, b) = 100b-2b²
A'(a, b) =100-4b [First derivative of the objective function]
A'(b)=0
100-4b=0
4b=100
b=25 [Critical point]
Applying sufficient condition for extremes
A'(b)=100-4b [First derivative of the objective function]
A''(b)=-4 [Second derivative of the objective function]
A''(b)=-4 [A''(b)<0∀b∈D]
b=25 [Maximum point of the objective function]
Calculate the dimension of the rectangular pigpen
b=25 [Width of the rectangular pigpen]
a=100-2(25)=50 [Length of the rectangular pigpen]
Therefore, the dimensions of the rectangular pigpen with the largest possible area are 50 ft×25 ft.

Mark was thinking of a number mark halves the number and gets an answer of 53.2 form an equations with x from the information
Answer: The number is 106.4
Step-by-step explanation:
Let the number be x
Mar halves the number becomes = x x 1/2 to get 53.2
The equation to solve this problem is x/ 2 = 53.2
Such that to find x
x/2= 53.2
x = 2 x 53.2= 106.4
The number is 106.4

Which of the following equations are equations of a direct variation? Choose all that apply.
(a) x=−2y
(b) x+2y=12
(c) 3x−2y=0
(d) 5x^2+y=0
(e) y =0.3x +1.6
(f) y−2=x
Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x This is equivalent to multiplying x by -1/2, so this is an example of direct variation.(b) x + 2y = 12
2y = 12 - x y = 6 - 1/2x This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.(c) 3x - 2y = 0
-2y = -3x y = 3/2x This follows the format of y = kx, so it is an example of direct variation.(d) 5x² + y = 0
y = -5x²This is not in the form of y = kx, so it is NOT an example of direct variation.(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.(f) y - 2 = x
y = x + 2 2 is being added to x, so it is NOT an example of direct variation.The following equations are examples of direct variation:
x = -2y 3x - 2y = 0Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x
This is equivalent to multiplying x by -1/2, so this is an example of direct variation.
(b) x + 2y = 12
2y = 12 - x
y = 6 - 1/2x
This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.
(c) 3x - 2y = 0
-2y = -3x
y = 3/2x
This follows the format of y = kx, so it is an example of direct variation.
(d) 5x² + y = 0
y = -5x²
This is not in the form of y = kx, so it is NOT an example of direct variation.
(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.
(f) y - 2 = x
y = x + 2
2 is being added to x, so it is NOT an example of direct variation.
The following equations are examples of direct variation:
x = -2y

Kathy uses 8.6 pints of blue paint and white paint to paint her bedroom walls. 4 5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:Kathy uses 1.72 pint of white paint
Step-by-step explanation:
Total amount of paint ( Blue and white paint)= 8.6 pints
Amount of blue paint=4/5 x 8.6 = 6.88 Pints
amount of white paint = Total amount of paint - amount of blue paint
= 8.6 pints - 6.88 pints
=1.72 pint of white paint

3x − x − 1 = 15
What is x
Answer: x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x−x−1=15
3x+−x+−1=15
(3x+−x)+(−1)=15(Combine Like Terms)
2x+−1=15
2x−1=15
Step 2: Add 1 to both sides.
2x−1+1=15+1
2x=16
Step 3: Divide both sides by 2.
2x /2 = 16 /2
x=8
Answer:
3x-x=15+1
2x=16
x=16/2
x=8

A line that has a slope of 1/3 and passes through the point (-9,5)
Answer:
[tex]y = \frac{1}{3}x + 8[/tex]
Step-by-step explanation:
using the slope-intercept formula, u have this so far as an equation (just knowing the slope): [tex]y = \frac{1}{3}x + b[/tex]
To find the y-intercept, substitute in the values of the coordinates given to solve for b:
[tex]y = \frac{1}{3}x + b\\5 = \frac{1}{3}(-9) + b\\5 = -3 + b\\8 = b[/tex]
so u can just put 8 into your slope-intercept formula ([tex]y = \frac{1}{3}x + 8[/tex]) and that's it! hope this helps!
