The polynomial p(x) = 3x³ - 5x² - 4x + 4 can be written as a product of linear factor as (x + 1) (3x - 2) (x - 2).
What is a polynomial?A polynomial is a mathematical expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables. It is made up of indeterminate (also known as variables) and coefficients.
Given:
p(x) = 3x³ - 5x² - 4x + 4
Factor = (x - 2)
Divide the equation by (x - 2) as shown below,
(3x³ - 5x² - 4x + 4) / (x - 2)
= (3x² + x - 2)
Factorize the above equation,
= 3x² - 2x + 3x - 2
= (x + 1) (3x - 2)
Therefore, the polynomial p(x) = 3x³ - 5x² - 4x + 4 can be written as a product of linear factor as (x + 1) (3x - 2) (x - 2).

The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at the fair. Jermaine spent his money only on ride tickets and fair admission. The price of the fair admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Define your variables.
(b) Write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission.
Answer:
see explanation
Step-by-step explanation:
$1.25 is the cost per ticket
Jermaine bought 25 tickets in total
Spent a total of $43.75
y = total cost
x = number of ride tickets
1.25 ( 25 ) = 31.25
31.25 is the total money spent on ONLY tickets.
To find the cost of admission...
43.75 - 31.25 = 12.50
The cost of admission is $12.50
Equation: 1.25x + 12.5 = y

Write an equation for a rational function with the given characteristics.
Vertical asymptotes at
x = −3
and
x = 6,
x-intercepts at
(−4, 0)
and
(1, 0),
horizontal asymptote at
y = −3
Answer:
y = -3(x +4)(x -1)/((x +3)(x -6))
Step-by-step explanation:
You want a rational function with vertical asymptotes at -3, 6; x-intercepts at -4, 1; and a horizontal asymptote at y = -3.
Vertical asymptotesA rational function will have vertical asymptotes at the denominator zeros. Vertical asymptotes at -3 and 6 will be had if the denominator has factors (x +3) and (x -6).
X-interceptsA rational function will have x-intercept at the numerator zeros. X-intercepts at -4 and 1 will be had if the numerator has factors (x +4) and (x -1).
Horizontal asymptotesA horizontal asymptote will be found at the y-value that is the (constant) ratio of the highest-degree terms of the numerator and denominator. Here, we can achieve that by multiplying the factors mentioned above by the desired constant (-3).
The equation is ...
[tex]\boxed{y=-3\dfrac{(x+3)(x-6)}{(x+4)(x-1)}}[/tex]
__
Additional comment
A "hole" will be found where a numerator and denominator factor cancel. For example, a hole at x=7 could be achieved by making the function have an additional numerator factor of (x -7) and an additional denominator factor of (x -7).
Effectively, the horizontal asymptote is the quotient of the numerator and denominator (excluding the "remainder"). If that quotient is a linear (or other) function, the graph will asymptotically approach that function as the magnitude of x gets large. A linear function gives a "slant aymptote."

A truck driver is driving from Nome, Alaska, to Death Valley, California. Because he is traveling between locations with extreme temperatures, he needs to check the weather continuously to make sure the gas in his truck remains in liquid form. The gas he uses freezes at −40° F and evaporates at 140° F.
Part A: Write an inequality to represent the temperatures at which the gas in the truck will remain in liquid form. (2 points)
Part B: Describe the graph of the inequality completely from Part A. Use terms such as open/closed circles and shading directions. Explain what the solutions to the inequality represent. (4 points)
Part C: In January 1989, the temperature in Nome, Alaska, dropped to −49° F. Would the gas in the driver's truck have remained in liquid form so he could have driven on this day? Why or why not? (4 points)
(A) The required inequality is, -40°F < x < 140°F.
(C) The gas has freezing point of -40°F, that means below that temperature the gas will freeze.
What is inequality?
In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.
(A) Let the liquid range is from -40°F to 140°F.
Let x be the range.
So, the required inequality is,
-40°F < x < 140°F
(B) The graph of inequality is attached below.
(C) Since the gas has freezing point of -40°F, that means below that temperature the gas will freeze.
(-49°F < 40°F)
Hence, the gas will freeze.

If Triangle ABC has been translated 4 units to the right into Triangle DEF, what are the coordinates of Point E?
Triangle ABC has been translated 4 units to the right into triangle DEF. Then, the coordinates of point E is (6, -2).
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Given that, triangle ABC has been translated 4 units to the right into Triangle DEF.
From the given coordinate plane A(-8, -2), B(2, -2) and (-4, -9)
When the shape is moved towards the right by k units, then replace x with x + k.
Now,
A(-8, -2) → D(-8+4, -2)=D(-4, -2)
B (2, -2) → E(2+4, -2)=E(6, -2)
C (-4, -9) → F(-4+4, -9)=F(0, -9)
Therefore, the coordinates of point E is (6, -2).

For his birthday, Zack and three of his friends went to a movie. They each got a ticket for $8.00 and the same snack from the concession stand. If Zacks mom paid $48 for the groups tickets and snacks how much did each snack set cost?
Answer:
$4.00
Step-by-step explanation:
There is, in total, 4 people attending the movies. [Zack and his 3 friends]
If each ticket costs $8.00, we can use 4 x $8.00 to find out how much the tickets costs.
4 x $8.00 = $32.00
If his mom paid $48 dollars in total, to get the amount of money they spent on snacks, we can use $48 - $32.
$48 - 32 = $16
We can now divide $16.00 by 4, as everyone [Zack and his 3 friends] got the same snack from the concession stand, and that leaves us with the equation: $16/4 [also known as 16 divided by 4]
$16/4 = $4.00
Each snack set cost $4.00

We have,
2 inches = 5 feet.
The dimensions of the garden on the scale drawing.
= 15 inches x 10 inches

2 inches = 5 feet
15 inches = 15/2 x 5 feet
15 inches = 37.5 feet
10 inches = 10/2 x 5 feet
10 inches = 25 feet

Solve for the legs of the 45-45-90 triangle.
Answer:
1st answer option
Step-by-step explanation:
the 45° side angles make this an isoceles triangle (both legs are equally long).
therefore, x = y.
Pythagoras gives us
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90° angle), and a and b being the legs.
so, we have
(5 × sqrt(2))² = x² + y² (remember, x = y)
(5 × sqrt(2))² = x² + x²
25 × 2 = 2x²
25 = x²
x = 5
because of x = y
y = 5

tina spends 65$ on supplies to start a dog washing business. she earns $21 every time she washes a dog. what is w, the number of dogs tina must wash to earn a profit of $40
By solving an equation, we know that the value of w or the number of dogs Tina must wash to earn a profit of $400 is 5.
What are equations?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
So, using the information given, the equation can be formed as:
21w - 65 = 40
Now, solve for the subject w to get the value of w as follows:
21w - 65 = 40
21w = 40 + 65
21w = 105
w = 105/21
w = 5
Therefore, by solving an equation, we know that the value of w or the number of dogs Tina must wash to earn a profit of $400 is 5.
