#8 is kind of a handful. But if you just look at what 'y' is doing as 'x' increases ... no matter where you look, 'y' is always decreasing whenever 'x' increases, so that's certainly not a 'direct' relationship.

#9 is correct. Good work.

Graph a linear function which has a rate of change equal to the average rate of change of function f on the interval [-1, 1]. Th

fomenos

<h2>Answer:</h2>

The linear function is given by:

$y=\dfrac{3}{2}x-\dfrac{7}{2}$

<h2>Step-by-step explanation:</h2>

It is given that the rate of change of the linear function is equal to the average rate of change of function f on the interval [-1, 1].

The slope(m) or average rate of change of the linear function will be:

$m=\dfrac{f(1)-f(-1)}{1-(-1)}\\\\\\m=\dfrac{-2-(-5)}{1+1}\\\\\\m=\dfrac{-2+5}{2}\\\\\\m=\dfrac{3}{2}$

and the linear function pass through (1,-2)

We know that the equation of a line with given slope m and passing through point (a,b) is given by:

Here (a,b)=(1,-2)

and $m=\dfrac{3}{2}$

Hence, the equation of linear function is:

$y-(-2)=\dfrac{3}{2}\times (x-1)\\\\\\y+2=\dfrac{3}{2}x-\dfrac{3}{2}\\\\\\y=\dfrac{3}{2}x-\dfrac{3}{2}-2\\\\\\y=\dfrac{3}{2}x-\dfrac{7}{2}$

A baseball manager has 11 players of the same ability. How many 9 player starting lineups can he

Lana71 [14]

Answer:

Step-by-step explanation:

Combination will be used here as teams are a group.

So using combination:

<em>No. of combination of 'n' things taken 'r' at a time</em>

<em> $\limits^n {C} \,_r$ = $\frac{n!}{r! (n-r)!}$ </em>

here n = 11 ,

r = 9

11<em>C</em>9 <em>= $\frac{11!}{9! (11-9)!}$ = $\frac{11!}{9! (2!)}$ </em>

11<em>C</em>9<em> =</em><em> 55</em>

<em>Which are the possible 9 player starting lineups</em>
