15 is coefficient, a is a variable, 2 and -7 are like terms, 15a is a term and 2 and 7 are constants.
The answer is d.
150 180-30= 150

Answer:
When x <= 8000
The cost remains constant at 0.35 when x increases from 0 to 8000
The slope of cost function over this part is 0
When 8000 < x <= 20000
The cost remains constant at 0.75 when x increases from 8000 to 20000
The slope of cost function over this part is 0
When 20000 < x <= 42000
The cost decreases when x increases from 20000 to 42000
The slope of cost function
m= -5 × 10^-6
It's an acute isosceles triangle. Because all the angles are acute (acute) and only two sides are equal (isosceles) :) hope this helps :)
