Answer:

3

Step-by-step explanation:

Assuming you meant f(x)=-16x^{3}-7x^{2} -1 the degree is 3. The degree of a polynomial is always the highest degree one single term has. In this -16x^{3} has a degree of 3, which is the highest in the polynomial, and therefore the answer. The degree of a term is the exponent or what the power of the term is. If the polynomial is in standard form, the degree will always be the first exponent.

A first number plus twice a second number is 13 Twice the first number plus the second totals 35 Find the numbers.
Sophie [7]

Answer:  the first number is 19 and second number is -3

Step-by-step explanation:

Let the First number be represented as  x

and  second number be represented as  y

Therefore, A first number plus twice a second number is 13 be expressed as

x + 2y = 13-----equation 1

also  Twice the first number plus the second totals 35

2x+ y = 35---- equaton 2

Step 2 --- Solving

x + 2y = 13-----equation 1

2x+ y = 35---- equation 2

By substitution, making x subject of formulae in equation 1

x+ 2y = 13

x= 13 - 2y

putting the value of x= 13- 2y in equation 2

2( 13 - 2y) + y= 35

26 - 4y + y= 35

-4y + y= 35- 26

-3y= 9

y = 9/-3

y= -3

To Find x , using equation 1

x + 2y = 13

x+ 2 x -3= 13

x-6=13

x= 13+6

x= 19

Therefore the first number = 19 and the second number = -3
