B. Perform the indicated operations. Write your SOLUTION and FINAL ANSWER. 1. (5x4 – 3x2 + 4) + (6x3 – 4x2 – 7)
2. Add (2x5 - 6x3 - 12x2 - 4) and (-11x5 + 8x + 2x2 + 6)
3. (2x2y – 5xy + 3y2) – (7xy – 6y2 + 5x2y)

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
