Answer:

\frac{-20}{-4+(-15)(-2)} = \frac{-10}{13}

Step-by-step explanation:

Given expression

           =  \frac{-20}{-4+(-15)(-2)}

           =  \frac{-20}{-4+30}

          = \frac{-20}{26}

         = \frac{-10}{13}

\frac{-20}{-4+(-15)(-2)} = \frac{-10}{13}

Write 2x3 − 3x2 + x5 in standard form. What is the classification of this polynomial by its degree? by its number of terms?
andrew-mc [135]

Answer:

  x⁵ +2x³ -3x², degree 5, 3 terms

Step-by-step explanation:

We assume you intend your expression to be ...

  2x³ -3x² +x⁵

The superscript numbers are exponents. Each indicates the degree of the term. In standard form, terms are listed in decreasing order by degree:

  x⁵ +2x³ -3x² . . . . standard form

The degree of the polynomial is the degree of the highest-degree term: 5.

The number of terms is the number of products in the sum: 3.

Collect like terms

2x^3-x^3+11x^2+2x^2+5-2

x^3+13x^2+3

The value of x satisfying both the equations 4x – 5 = y and 2x – y = 3, when y = -1 is
schepotkina [342]

Answer:

x = 1

Step-by-step explanation:

4x-5=y

4x-5= -1

4x = -1+5

4x=4

x=1

2x-y=3

2x-(-1)=3

2x+1=3

2x= 3-1

2x= 2

x=1

since the two answers for x are the same therefore:

x = 1
