Answer:
Hence the correct option is the last one . The triangle is an obtuse angled triangle.
Step-by-step explanation:
i) the sum of any two sides added together is greater than the third side hence this is a triangle.
ii) it is<em><u> not</u></em> a right angled triangle as
and 
iii) the triangle is not acute from ii) above
iv) the triangle is an obtuse triangle from ii) above.
Instead of using an = sign we use

becuase its less than or equal to 100 dollars.
The equation of the line is y=10x+7
sub in 100 for y and the inequallity sign
10x+7

100
solve so x is isolated
10x

93
x

9.3
technically the answer is 9 because you cant buy a fraction of a CD
