Answer: 0 triangles are possible
The given angle is 98 degrees which is already obtuse. We can't have more than one obtuse angle.
Image of graph The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
x = number of months
7*x = 7 times the number of months
7*x = total cost if you ignore the $100 fee
7x+100 = total cost with the fee of $100 included
y = total cost
y = 7x+100
Final Answer: y = 7x+100
note: the slope is 7 and the y intercept is 100
