Answer:

The first/top table represents a function

Step-by-step explanation:

This is because all the input values are different. In the second table, there are 2 input values of "3". In the third table, there are 2 input values of "-8" and in the last table there are 2 input values of "10" and 2 input values of "20".

What is the greatest common factor of 9x^2<br> 2<br> and 6x?

zheka24 [161]

Answer:

The greatest common factor is 1.

Step-by-step explanation:

In this question we will factorize the expressions given and select the common factors among all.

For 9x² = 1×3×3×X×X

For 2 = 1×2

For 6x = 1×2×3×X

So we find the common factor in all expressions is = 1

Simplify the polynomial. Then find its value for the given value of the variable.

vekshin1

Answer:

Step-by-step explanation:

Simplified expression:

$3x^3 -x^3 +5x^3-9x^3$

$2x^3 +5x^3-9x^3$

$7x^3 -9x^3$

$-2x^3$

If x = -1, the value of the expression is:

$-2x^3$

$-2(-1^3)$

$-2(-1)$

$2$

Can you check my answers and help with number 3?

mamaluj [8]

Answer: Question 1 :B,D.

Question 2:option B,

Question 3:Degree=5.

Question 4:option D.

Question 5: option c.

Step-by-step explanation:

1) A polynomial can not have any exponent as a variable or a fraction.

Options B and D are polynomials.

2) The polynomial is having 3 terms and is of degree 3.so it is a cubic trinomial Option B.

3) Degree is the highest power of the variables in the terms .The term $6x^{3} y^{2}$ has the power=3+2=5

So degree =5.

4) $(5x-2+3x^{2} )+(4x+3)=3x^{2} +5x+4x-2+3=3x^{2}+9x+1.$

Option D

5) $(5x^{2} +2x-5)-(3x^{2}+3x+1)= 5x^{2}+2x-5-3 x^{2}-3x-1$

Simplifying like terms,

= $2x^{2}-x-6.$

Option c.
