The quotient rule is as follows
((l)•(h’) - (l’)•(h))/(l)^2
With l representing “low” or “bottom equation” and h representing “high” or “top equation”
Let’s plug in v^k and v^h in this case
((v^h)(v^k)’ - (v^h)’(v^k))/(v^h)^2
That would be 106.5 degrees
-2(2b-3)
Multiply the bracket by -2
Whenever multiplying a -negative number with a -negative number= + positive number.
(-2)(2b)(-2)(-3)
-4b+6
Answer: -4b+6
