Using complete sentences, explain how to find the average rate of change for f(x) from x = 4 to x = 7.

1 answer:

4 0

Really you just need to plug in each one. So 4 plugged into x in the equation comes out to be 87. And if you plug in 7 it comes out to be 93. so if you take 93 subtract 87 from it, it comes to be 6. and if you take 7 and subtract 4 from it you get 3. So when we plug it in it doubles. So the average rate of change(slope) is 2. because 6/3=2. Average rate of change is the exact same thing as slope.

Arjun solved the equation 7·m=56 His work is shown. What error did Arjun make?

natulia [17]

He multiplied rather than dividing.

$\mathrm{Divide\:both\:sides\:by\:}7 \ \textgreater \ \frac{7m}{7}=\frac{56}{7} \ \textgreater \ Simplify \ \textgreater \ m = 8$

Hope this helps!
