The correct answer for the question that is being presented above is this one: "(1) <span>For all real numbers a and b, a + b = b+ a; </span>(2) For all real numbers a and b, ab = ba; (3) <span>For all real numbers a, b and c, (a + b) + c = a + (b + c); (4) </span><span>For all real numbers a, b and c, a (b + c) = ab + ac." </span>
Answer:
-8/10, -3/16, 3/16
Step-by-step explanation:
The difference between Tucker and Karly's take is that Tucker's solution is analytical while Karly's is graphical. But both are correct either way.
For Tucker's solution, let's say at x=-3 the value for y is 4, and at x=3, the value of y is still 4, then the average rate of change or slope is 0. Note that the slope of the curve is Δy/Δx. Since there is no change for Δy, the slope is zero.
For Karly's solution, even if the curve travels high or low but would have the same elevation of x=-3 and x=3, the average rate of change is still zero. It is actually just same with Tucker's but Karly just verbalizes her solution that was observed visually.
