10)So plug in the value of a + 3 into where the x of the equation 
r(a+3)=  6                                  6        *you can simply if you want*
            -------                        ______
             (a+3)8  distribute=24 + 8a

11) f(-2)=n whenever you have f with a # inside the parenthesis know that they're giving you the x value so f(x)= and on this side is the y value but on tables y value are titled as f(x). So f(-2) is 3

12)Instead of giving you the x-value they gave you the y value this time "=9?" on the bottom. So you go to the f(x) column and find 9 and the # next to it which is 0

Sarah bought a 20oz can of tomato sauce for $25.40.What is the unit Price per ounce
ddd [48]
If the can is 20oz and cost $25.40, the price per ounce would be:

\frac{price}{ounce}

price = $25.40
ounce = 20oz

so:

\frac{25.40}{20}

which comes out to be:

$1.27/oz

So each ounce of tomato sauce costs $1.27!

A basketball player is shooting a basketball toward the net. The height, in feet, of the ball t seconds after the shot is modele
arsen [322]

The shot was blocked between 0.84 and 0.85 seconds after the shot is launched.

<h3>what will be the time in which the blocker will block the ball?</h3>

The given equation for ball height

=6+30t-16t^{2}

The equation for the blocker's height will be

=9+25t-16t^{2}

But, the shot is made before two-tenths of a second or 0.2 seconds therefore modified equation for ball height is

=6+30(t-0.2)-16(t-0.2)^{2}

Now for the shot to be blocked, the height of the shot-blocker must be greater than the height of the ball which is shot before 0.2 seconds :

9+25t-16t^{2} \geq 6+30(t-0.2)-16(t-0.2)^{2}

9+25t-16t^{2} \geq6+30t-6-16(t^{2} -0.4t+0.04)

9+25t-16t^{2} \geq30t-16t^{2} -6.4t+0.64

9+25t\geq36.4t-0.64

9.64\geq11.4t

t \leq \dfrac{9.64}{11.4}=0.846

Thus the shot was blocked between 0.84 and 0.85 seconds after the shot is launched.
