Answer:

Slope of Function B = - Slope of Function A

Step-by-step explanation:

Function A

f(x) = - 2x + 1

This is in the form y = mx+b where m is the slope

The slope is -2


Function B

We have 2 points so we can calculate the slope

(0,-3) and (2,1)

m = (y2-y1)/(x2-x1)

   = (1--3)/(2-0)

   = (1+3)/(2-0)

    =4/2

2



Slope of A = -2       Slope B =2

The are opposites

What is the difference written in scientific notation? 0.00067 - 2.3 x 10^5
shepuryov [24]
0.00067=67X10^5 so

67X10^5-2.3X10^5

64.7X10^5 which can be expressed as:

6.47X10^6

(not sure if it matters to you or not, but technically we only had two significant figures so it should be rounded to 6.5X10^6)
