Answer:

x < -3/2 OR x > 9  3/5

Step-by-step explanation:

12x+7<−11 OR 5x−8>40

Solve the inequalities separately

12x+7<−11

Subtract 7 from each side

12x+7-7<−11 -7

12x < -18

Divide each side by 12

12x/12 < -18/12

x < -3/2

Then solve the other inequality

5x−8>40

Add 8 to each side

5x-8+8>40+8

5x>48

Divide each side by 5

5x/5 >48/5

x > 9  3/5

Put them back together with the OR in the middle

x < -3/2 OR x > 9  3/5

Answer:

x < -1.5 U x > 9.6

Step-by-step explanation:

Nutka1998 [239]

Let's look over the meaning of each option:


Theocracy: Theo- means that it is relating to religion. For example, Theology is the study of religion. This is a system where religious leaders control the country, but it is NOT an economic system.

Monarchy: Monarchy is when there is a king, queen, emperor, etc. It is not an economic system either.

Fundamentalism: A political system that strictly abides by a set of fundamentals. Someone who wants a constitution to be the highest form of law is a fundamentalist. However, this is also not an economic system.

Socialism: WINNER WINNER CHICKEN DINNER! Socialism is a system similar to communism where the government controls the economy and there is communal ownership. This is also the only option which is both a political and economic system.


TL;DR: The answer is Socialism.

Ok, make sure you put the powers correctly. I know what you mean but someone else may not. So it's step 2. This is because the 4 doesn't mean add a digit.

According to the Fundamental Theorem of Algebra, which polynomial function has exactly 8 roots?
HACTEHA [7]

Answer:

Option (1)

Step-by-step explanation:

Fundamental theorem of Algebra states degree of the polynomial defines the number of roots of the polynomial.

8 roots means degree of the polynomial = 8

Option (1)

f(x) = (3x² - 4x - 5)(2x⁶- 5)

When we multiply (3x²) and (2x⁶),

(3x²)(2x⁶) = 6x⁸

Therefore, degree of the polynomial = 8

And number of roots = 8

Option (2)

f(x) = (3x⁴ + 2x)⁴

By solving the expression,

Leading term of the polynomial = (3x⁴)⁴

                                                     = 81x¹⁶

Therefore, degree of the polynomial = 16

And number of roots = 16

Option (3)

f(x) = (4x² - 7)³

Leading term of the polynomial = (4x²)³

                                                    = 64x⁶

Degree of the polynomial = 6

Number of roots = 6

Option (4)

f(x) = (6x⁸ - 4x⁵ - 1)(3x² - 4)

By simplifying the expression,

Leading term of the polynomial = (6x⁸)(3x²)

                                                     = 18x¹⁰

Degree of the polynomial = 10

Therefore, number of roots = 10
