We have supplementary angles.

I) 2(x+25) +2x-30=180 ⇒ 2x+50+2x-30=180 ⇒ 4x = 160 ⇒ x = 40°

II) 13w+4w+10=180 ⇒ 13w + 4w = 180 - 10⇒ 17w = 170  ⇒ w = 10°

The graph of f "(x) is continuous and decreasing with an x-intercept at x = 0. Which of the following statements is true?
kari74 [83]

Answer:

The graph of f has an inflection point at x = 0.

Step-by-step explanation:

An inflection point occurs when the second derivative changes signs.  Since f"(x) is decreasing and has an x-intercept at 0, it changes signs from + to -, so there is an inflection point at x = 0.

The polynomial 3x2 is a with a degree of .
ZanzabumX [31]

To determine the degree of a polynomial, you look at every term:

  • if the term involves only one variable, the degree of that term is the exponent of the variable
  • if the term involves more than one variable, the degree of that term is the sum of the exponents of the variables.

So, for example, the degree of 7x^{55} is 55, while the degree of xy^2z^4 is 1+2+4 = 7

Finally, the term of the degree of the polynomial is the highest degree among its terms.

So, 3x^2 is a degree 2 polynomial (although it only has one term)

similarly, x^2y + 3xy^2 + 1 is a degree 3 polynomial: the first two terms have degree 3, because they have exponents 2 and 1.

Goodmorning all help me guys​
kotegsom [21]

Answer:

Step-by-step explanation:

1) Distance covered by motorcycle = x

y  = 50 + (x -2)*10

2)Distance traveled = 5 km

y = 50 + ( 5-2) *10

  = 50 + 3*10

  = 50 + 30

  = 80

Seth will be paid Php 80

3)  y = 120

50 + (x - 2)* 10 = y

50 + (x -2) *10 = 120

50 + 10x - 2*10 = 120

50 + 10x - 20  = 120

30 + 10x = 120

       10x = 120 - 30

       10x = 90

           x = 90/10

x = 9

A passenger can travel 9 km.

4)y = (x - 2)*10

 y = 10x - 20

20 + y = 10x

     20 = 10x - y

10x - y = 20      {Ax + By = C form}
