Ration expressions cause excluded values wherever the denominator equals zero.
So, for any expression like
-5 is an excluded value if 
For example, the simplest one would be
In fact, if you try to evaluate this function at -5, you'd have
which is undefined, and thus you can't evaluate the function, and thus -5 is an excluded value.
Answer: speed = 585/(13/2) = 90 miles per hour.
Step-by-step explanation:speed = distance / time
since they are moving in opposite direction, the time is the sum of the two times = 2 1/2 + 4 = 6 1/2 = 13/2
Figure A’B’c’d is equal to the measure of angle A
Answer:
D
Step-by-step explanation:
first of all we need to solve the inequalities
(-∞,1] or ]-∞,1]
the second inequality is
[2,∞) or [2,∞[
so the answer is D
