<span>When flipping two standard American quarters, there are four independent possible outcomes: -Tails, tails -Heads, heads -Heads, tails -Tails, heads Looking, then, at these four outcomes, there are three of those that include at least one head. As such, the answer to this question is three possibly different ways for her to achieve the desired outcome.</span>

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:

$f (x) = 5x$

For $x = 2$ we have:

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

Answer:

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

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
