Let a, b, c, and d be constants. Describe the possible solution sets of the inequality ax+b
An inequality's solution set is determined by its specific properties. For a quadratic inequality, it can be solved by first finding the roots with the quadratic formula and then testing ranges between the roots to see where the inequality holds.
Explanation:The question seems a bit incomplete, as there is no inequality provided related to constants a, b, c, and d. Typically, if we had a complete inequality, the solution set would depend on the specifics of the inequality. For instance, if we took a quadratic inequality, ax²+bx+c>0, or ax²+bx+c<0, we would solve it by finding the roots using the quadratic formula (-b ± √b² - 4ac) / 2a, which gives us the values of x where the expression equals zero, and testing regions determined by these roots to find where the inequality holds. However, without a specific inequality provided, it's difficult to describe the possible solution sets accurately.

Marco wants to set up 12 small turbines with 3 blades each.If 4 wind turbines blades cost $79.64,how much will all the blade cost?
If Marco wants to set up 12 small turbines with 3 blades each. If 4 wind turbines blades cost $79.64 then $716.76 costs for all blades.
What is Equation?Two or more expressions connected with an equal sign is called ad equation.
Given Marco wants to set up 12 small turbines with 3 blades each. If 4 wind turbines blades cost $79.64, then we have to find the cost of all blades.
Each turbine has 3 blades, so for 12 tubines we have
3×12=36 blades.
If 4 blades cost is $79.64, then we have to find cost of 36 blades.
Let y be the cost of 36 blades.
4 /36= 79.64/y
Use cross multiplication,
4 * y = 36 * 79.64
4y = 2,867.04
y=716.76
Therefore 36 blades cost is $ 716.76.

The requried factor of the given quadratic expression [tex]3x^2 + 4x - 4[/tex] is (3x-2). Option C is correct.
To find the factor of the quadratic expression [tex]3x^2 + 4x - 4[/tex], we need to identify two binomials that, when multiplied together, result in the given expression.
The expression is in the form of [tex]ax^2 + bx + c[/tex], where a = 3, b = 4, and c = -4.
To factor the quadratic expression, we look for two binomials of the form (mx + p) and (nx + q) such that:
(mn) = a (which is 3 in our case), and
(pq) = c (which is -4 in our case).
Now, we need to find the factors of 3 and -4:
Factors of 3: 1, 3
Factors of -4: 1, -1, 2, -2, 4, -4
Now, we need to find combinations of these factors such that their product is 3 (the coefficient of [tex]x^2[/tex]) and -4 (the constant term). The combination that works is:
3 * -1 = -3
So, the two binomials are (3x - 2) and (x + 2) because:
[tex](3x - 2) * (x + 2) = 3x^2 - 2x + 6x - 4\\ \ \ \ \ \ \ \ \ \ \ = 3x^2 + 4x - 4[/tex]
Therefore, the correct factor is C.) (3x - 2).

Given the inequality -8 < 2, explain what happens when you multiply or divide both sides by 2 and what happens when you multiply or divide both sides by -2.
When you multiply or divide each side by 2, the signs stay the same. −16 < 4 and −4 < 1. When you multiply or divide by −2, the inequality sign reverses. 16 > −4 and 4 > −1.

Which polynomial is prime? x3 + 3x2 – 2x – 6 x3 – 2x2 + 3x – 6 4x4 + 4x3 – 2x – 2 2x4 + x3 – x + 2
A prime polynomial is a polynomial that can't be factored.
In order to check which polynomial is prime, we need to check which polynomials could be factored.
x^3 + 3x^2 – 2x – 6 can be factored as (x+3)(x^2-2)
x^3 – 2x^2 + 3x – 6 can be factored as (x-2)(x^2+3)
4x^4 + 4x^3 – 2x – 2 can be factored as 2(x+1)(2x^3-1)
2x^4 + x^3 – x + 2 can't be factored.
Therefore, 2x^4 + x^3 – x + 2 is a prime polynomial.
In this exercise we have to use the knowledge of prime polynomials to find what cannot be factored, so we have;
A) Can be factored.
B) Can be factored.
C) Can be factored.
D) Can't be factored.
Is a base form of a polynomial in other words is a polynomial that can't be factored.

Dina and Masha started out on a 10 km bike path at the same time. When Dina reached the end of the 10 km, Masha still had 2 km left to bike. If Dina’s biking speed was 5 km/h, find Masha’s biking speed.
Answer:
4 km/hr
Step-by-step explanation:
Dina and Masha started out on a 10 km bike path at the same time.
Distance = 10 km
Dina’s biking speed was 5 km/h
Time taken by Dina is Distance / speed
So [tex]time (Dina) = \frac{10}{5} =2[/tex]
Time taken by Dina is 2 hours
Same time is taken by Masha but 2 km left
So distance covered by Masha in 2 hours is 10-2 = 8 km
We know speed = distance / time
[tex]speed of Masha = \frac{8}{2}=4[/tex]
Masha’s biking speed= 4km/hr
