Given a polynomial functin
ax^2+bx+c, the highest degree is 2
given another polynomial say ax^3+bx^2+cx+d, the degree of the polynomial is 3.
 From the above we can conclude that the degree of a polynomial is its highest power. 
From the function given:
5+7x^9+12x-5x^7+3x^2

The highest power is 9, thus it is a polynomial of degree 9. 

The coefficient of the term of degree 9 is 7.

The answer is 7.

Maya is showing her work in simplifying (5.2 − 4.5) − 5.5 + 4.8. Identify any error in her work or reasoning.
Dmitry_Shevchenko [17]
If putting 5.2 and 4.5 in fraction form, her error must have been timing 3 by 3 to 5.2 and 4.5 as a fraction. Meaning that 5.5 and 4.8 is wrong

Which statements are true about the ordered pair (2, 3) and the system of equations?
adoni [48]

Answer:

The Correct Answer are

  • The ordered pair (2, 3) is not a solution to the system of linear equations.
  • When (2, 3) is substituted into the first equation, the equation is true.
  • When (2, 3) is substituted into the second equation, the equation is false.​

Step-by-step explanation:

The Correct Answer are

  • When (2, 3) is substituted into the first equation, the equation is true.

3x + 4y = 18   equation ( 1 )

3×2 + 4×3 = 18

6 + 12 = 18

18  = 18

  • When (2, 3) is substituted into the second equation, the equation is false.​

2x – 2y = 2

2×2 - 2×3= 4 - 6 = -2≠2

  • The ordered pair (2, 3) is not a solution to the system of linear equations.

Solution means if we (2, 3) Substitute in both the Equation it Must Satisfy

But in Equation 1  it Satisfy

and in Equation 2 Not satisfy

Therefore It is NOT a solution to the system.
