Answer:

  -203.1875

Step-by-step explanation:

The ends of the interval are ...

  (-4, g(-4)) = (-4, 1023 15/16)

  (1, g(1)) = (1, 8)

The average rate of change is the slope of the line between these two points:

  m = (y2 -y1)/(x2 -x1)

  m = (8 -(1023 15/16))/(1 -(-4)) = (-1015 15/16)/5 = -203 3/16

The average rate of change on the interval is -203 3/16.

For the triangle picture:

2/6 = 5/x

2x = 30

x = 15


For the other picture:

3.2/2 = a/8

The third option applies.


Other option does not apply.
Because for Option 4,
It should be 2/3.2 = b/6.4

For option 3,
it should be b/6.4 = 5/8

write an equation in point-slope form of the line that passes through the point (3, 5) and has a slope or -1
frez [133]

Answer:

y = -x + 8

Step-by-step explanation:

m = -1  ; x1 = 3 ; y1 = 5

Slope point form: y - y1 = m(x -x1)

y - 5 = -1(x - 3)

y -  5 = -1x - 3 *(-1)

y - 5 =-x + 3

    y =  -x + 3 + 5

     y = -x + 8
