Consider the function f(x)=−5x−8 and find the following: a) The average rate of change between the points (−1,f(−1)) and (3,f(3)
kipiarov [429]

Answer:

a. -5

b.-5

c.-5

Step-by-step explanation:

In order to find the average rate of change of a function , we divide the change in the output value by the change in the input value.

Generally, the average rate of change (ARC) on an ecuatios  between two points (x1,f(x1)) and (x2,f(x2)) is

  • ARC = [f(x2)-f(x1)]/ (x2-x1)

<em>In case a)</em>

f(-1)= -5*(-1)-8=5-8= -3          f(3)= -5*3-8= -23

Then ARC= (-23-(-3))/(3-(-1))=-20/4=-5

<em>In case b)</em>

f(a)= (-5a-8)

f(b)= (-5b-8)

Then ARC= [(-5b-8)-(-5a-8)]/(b-a)= (-5b+5a)/(b-a)= -5(b-a)/(b-a)= -5

<em>In case c)</em>

f(x)= -5x-8

f(x+h)= -5(x+h)-8= -5x-5h-8

then ARC= [(-5x-5h-8)-(-5x-8)]/(x+h-x) =-5h/h= -5

Simplify 3-(4x-5)+6.
Leviafan [203]
3 + -4x = 5(x +6)

Re-order the terms:

3 + -4x = 5(6 + x)
3 + -4x = (6 . 5 + x . 5)
3 + -4x = (30 + 5x)

Solving:

3 + -4x = 30 + 5x

Solving for variable "x"

Move all terms containing "x" to the left, all the other terms to the right.

Add "-5x" to each side of the equation.
3 + -4x + -5x = 30 + 5x + -5x

Combine like terms: 
-4x + -5x = -9x
3 + -9x = 30 +5x + -5x

Combine like terms: 
5x + -5x = 0
0 + -9x = 30 +0
3 + -9x = 30

Add "-3" to each side of the equation.
3 + -3 + -9x = 30 + 3

Combine like terms: 
3 + -3 = 0
0 + -9x = 30 + -3
-9x = 30 + -3

Combine like terms: 
30 + -3 = 27
-9x = 27

Divide each side by "-9".
x = -3

Simplifying:
x = -3
