Anthony's weight is nine pounds more than twice his brothers weight. Anthony's weighs 59 pounds. how much does his brother weigh
ahrayia [7]
A = Anthony's weight
B = Anthony's brother's weight

  A = 2B + 9   Plug in Anthony's weight
59 = 2B + 9   Subtract 9 from both sides
50 = 2B   DIvide both sides by B
25 = B   Switch the sides to make it easier to read
  B = 25

Anthony's brother weighs 25 pounds.

Use the following graph of the function f(x) = 2x3 + x2 − 3x + 1 to answer this question: graph of 2x cubed plus x squared minus
Zina [86]

Answer:

7

Step-by-step explanation:

f(x) = 2x^3 + x^2 − 3x + 1

f'(x) = 6x^2 + 2x − 3

The slope at -2:

f'(-2) = 6(-2)^2 + 2(-2) − 3

f'(-2) = 24 + -4 − 3

f'(-2) = 17

-----

The slope at 0:

f'(0) = 6(0)^2 + 2(0) − 3

f'(0) =  − 3

The average rate of change is (17+(-3))/2, or 14/2, or 7
