Damian took out a car loan for $10,500 that has a 0% APR for the first 12

You can solve this via algebra, lets say the numbers are x and y.
x + y = 43 and x - y = 19

You can re-arrange one of the equations to get

x = 43 - y Then substitute this into the other equation, so instead of x you put this:

(43 - y) - y = 19
43 - 2y = 19
-2y = 19 - 43
-2y = -24
-y = -12
so y = 12
then you can do 43 - 12 = 31 to get both of the numbers.
so the numbers are 31 and 12

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 :

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