Answer:

option 4

Step-by-step explanation:

Solving the inequality

4.5 + 1.2x ≥ 10 - x ( add x to both sides )

4.5 + 2.2x ≥ 10 ( subtract 4.5 from both sides )

2.2x ≥ 5.5 ( divide both sides by 2.2 )

x ≥ 2.5

3, 4, 5, 6 are all greater than 2.5, thus

All values in the set make the inequality true

Step-by-step explanation:

The question is asking for the value of A when n = 2

So we just need to plug in 2 for n

A(2) = 10 + (<em>2</em>-1)(4) = 10 + (1)(4) = 10 +4 = 14

Bumek [7]

1. b+2=p. 4+2=p. 6=p.
2. p/2=a. 6/2=a. 3=a
3. b-a=x. 4-3=x. 1=x
I'm in HS but this seems like it is the answer. If you need more explanation ask.

Drag the expressions into the boxes to correctly complete the table. Polynomial Not a polynomial

uranmaximum [27]

The answer to the given question is as below:-

Polynomials:-

x³-7x²+9x-5x⁴-20

x⁵-5x⁴+4x³+2x-1

3x²-5x⁴+2x-12

Non-polynomial:-

x⁻5-5x⁻⁴+4x⁻³+2x⁻1-1

$\dfrac{4}{x^4}+ \dfrac{3}{x^3}-\dfrac{2}{x^4}-1$

$\sqrt[4]{x} -\sqrt[3]{x} 4+\sqrt{x}-8x+16$

<h3>What are polynomials?</h3>

A polynomial is a mathematical equation made up of indeterminates and coefficients and involves only addition, subtraction, multiplication, and non-negative integer exponentiation of variables. The exponents of the polynomials can not be irrational.

So the table will be formed as:-

Polynomials:- Non-polynomial:-

x³-7x²+9x-5x⁴-20 x⁻5-5x⁻⁴+4x⁻³+2x⁻1-1

x⁵-5x⁴+4x³+2x-1 $\dfrac{4}{x^4}+ \dfrac{3}{x^3}-\dfrac{2}{x^4}-1$

3x²-5x⁴+2x-12 $\sqrt[4]{x} -\sqrt[3]{x} 4+\sqrt{x}-8x+16$

Therefore the polynomials and non-polynomials are shown in the table above.
