b = 10 -2s
then s=0.5, this forms a triangle, why wouldn't it I'm confused??
A isosceles triangel has the perimeter 10 cm. Signb for the base and s for the sides.
Decide the function's domain and range. According to the key the answers should be:
How can these answers be possible? If the base are 9 cm, then the two sides of the triangel have to be 0.5 cm each and then they will not form a triangel. Can you please explain? Thank you in advance.
Can you finish from here? (You can make a similar solution for b by solving the b + 2s = 10 equation for s and sticking that into the inequality.)
