Answer:

C, D

Step-by-step explanation:

1.)

the best way to figure this out is just plug in -2 for x

3(-2^3)+11(-2^2)-4(-2)-6

I put this into a calculator and get 22

2/3.) see attachment below for work

but C is correct

4.) in number one we determined that p(-2) =22 so yes

5.) we determined in 2/3 that it is in fact not, so no

The correct option for the polynomial is p(x) = 3x³ + 11x² - 4x - 6 are option 3 and option 4.

 ax² + bx + c, where a, b, and c are real numbers with a 0, is the formula for a quadratic polynomial in 'x'  with real coefficients.

Degree: The degree of a polynomial is the highest exponent of the variable in the polynomial.

Calculation for the values of polynomial:

To get the value of p(-2), at the place of 'x' put (-2) in the polynomial p(x).

p(x) = 3x³ + 11x² - 4x - 6

p(-2) = 3(-2)³ + 11(-2)² - 4(-2) - 6

p(-2) = 22

Thus, option 4 is correct and option 1 is incorrect.

To calculate the quotient divide the polynomial p(x) by (x +2)

The solution of this is attached in the file.

Therefore, option 3 is correct and option 2 is incorrect.

As, we can see from the division of polynomial p(x) by (x + 2) , the p(x) polynomial is not completely divisible by (x +2). Therefore, option 5 is also incorrect.

5/6=0.83

4/5=0.8

Answer:

Step-by-step explanation:

There actually is an infinite number of fractions between 3/4 and 5/6. But to find a simple ones make the denominators the same.

(3/4)(6/6) and (5/6)(4/4)

18/24 and 20/24 so 19/24 is halfway between them.

Answer:

Step-by-step explanation:

The aim of this question is to prove that the product of two rationals is rational.

To proof:

If [tex]\mathbf{x \ and \ y}[/tex] are arbitrary rational numbers.

Thus, going by the definition of rational, there exist integers

a, b, ≠ 0, c, and d ≠ 0 ; [tex]x = \dfrac{a}{b} \ and \ y = \dfrac{c}{d}[/tex]

Hence, [tex]xy = (\dfrac{a}{b})(\dfrac{c}{d}) = \dfrac{ac}{bd}[/tex]

Since a and c are integers, then e = ac appears to be an integer as well.

Also, provided that b and d are non-zero integers;

f =bd appears to be a non-zero integer.

Therefore, [tex]xy = \dfrac{e}{f}[/tex], and going by the definition of rational, xy is rational.

Hence, from the complete question:

Answer:

so to factor out you find the greatest common factor of 14 and 7

if you have 2x-2 then you can factor out the 2 and get 2(x-1)

7=7*1

14=2*7

the greatest common factor is 7

14x-7=7(2x-1)

Step-by-step explanation:

First you multiply 2(y+10) with will get you (2y+20)

Answer: $150

Step-by-step explanation:

Becky spends 3/5 of her Money and is left with 2/5 of her money.

Hence 2 parts = $60

And 5 parts = $150

Becky has $150 at first.

Becky starts with $150.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Becky spends 3/5 of her money she has left £60 left.

let Becky earned be x.

so, x- 3/5x= 60

2x/5 = 60

x= 300/ 2

x=$150

Hence, Becky starts with $150.
