PLEASE HELP, WILL MARK BRAINLIEST !!!
shutvik [7]

Answer:

- 2

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ - 4, 3 ] , then

f(b) = f(3) = 3² - 3 - 8 = 9 - 3 - 8 = - 2

f(a) = f(- 4) = (- 4)² - (- 4) - 8 = 16 + 4 - 8 = 12 , tus

average rate of change = \frac{-2-12}{3-(-4)} = \frac{-14}{7} = - 2

If f(x) varies directly with x and f(x) = 40 when x = 8, find the value of f(x) when x = 2.
Mars2501 [29]

For this case we have a direct variation of the form:

f (x) = kx

Where "k" is the constant of proportionality. To find it, we use the following data:

f (x) = 40\ and\ x = 8

Substituting:

40 = k * 8

Clearing the value of k:

k = \frac {40} {8}\\k = 5

Thus, the direct variation is given by:

f (x) = 5x

Forx = 2 we have:

f (2) = 5 * 2\\f (2) = 10

Answer:

The value of the direct variation for x = 2is: f (2) = 10

Which of the following inequalities matches the graph? graph of an inequality with a dashed line through the points (0, 3) and (
Snezhnost [94]
(0,3)(1,9)
slope = (9 - 3) / (1 - 0) = 6/1 = 6

y = mx + b
slope(m) = 6
use either of ur points...(0,3)...x = 0 and y = 3
now sub and find b, the y int
3 = 6(0) + b
3 = b

ur equation is : y = 6x + 3

for an inequality, a dashed line means there is no equal sign in the problem...and shading above the line means greater then.

so ur inequality is : y > 6x + 3
