PLZ Three toy cars race down a straight path. The distance each car traveled in meters, over time measured in seconds, is shown in the graph below.

1. At what speed is each car traveling? Where can you see each speed in the graph?

2. Explain the significance of the coordinate point (1,r),What do you think the “r” represent?

vertical=18cm horizontal=18cm hypotenuse=25.5

step-by-step explanation:

x^2 + 10x + 38 + 161/x-4

to find this, you'll need to synthetically divide using synthetic division.

here's how you would set it up:

4 is what you're dividing by (set x -4 = 0)

the numbers you are 'dividing' by are 1, 6, -2, and 9 or the coefficients of the terms listed above.

bring the first term down (1), multiply that by 4 before raising it to the next term to add (6). repeat this process as so:

6 + 4 = 10; 10 x 4 = 40; 40 - 2 = 38 x 4 = 152 + 9 = 161

161 is over x-4 as there are now two constants and you cannot combine them.

also, i'm not sure if it was -9 or +9, so i assumed.

hope this !
