Answer 1

Answer:

Step-by-step explanation:

The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are [tex]x[/tex] and [tex]y[/tex].

To find the constant of proportionality, all we have to do is divide any value of [tex]y[/tex] by its corresponding value of [tex]x[/tex]. Let's take the values in the first row of the table. We know that [tex]x=2[/tex] and [tex]y=12[/tex], so the constant of proportionality is [tex]\frac{y}{x}=\frac{12}{2} =6[/tex]. Hope this helps!

Select the correct answer. One factor of the polynomial 2x^3–3 x^2 - 3x + 2 is (x- 2), which expression represents the other factor, or factors, of the polynomial?

Answers

Answer:

Step-by-step explanation:

The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.

The given expressions are 2x³-3x²-3x+2 and x-2.

What are factors of polynomial?

The factors are the polynomials which are multiplied to produce the original polynomial.

Here, the given polynomial can be factored as follows:

x-2 |2x³-3x²-3x+2| 2x²+x-1

2x³-4x²

(-) (+)

___________

x²-3x+2

x²-2x

(-) (+)

___________

-x+2

(-) (+)

____________

2x²+x-1 can be rewritten as 2x²+2x-x-1

= 2x(x+1)-(x+1)

= (x+1)(2x-1)

The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.

Answers

Answer:

2x + 18 ≥ 21

x ≥ 2/3

Step-by-step explanation:

Let sum be X

2 times the sum means 2x

the sum of a number and 18 means x + 18

at least -21 means ≥ 21

put them together, and you get, 2x + 18 ≥ 21

If solving for x,

2x + 18 ≥ 21

2x ≥ 3

x ≥ 2/3
