A cell phone plan costs $200 to start. Then there is a $50 charge each month. 1. What is the total cost (start-up fee and monthly charge) to use the cell phone plan for 1 month.

2. Write an equation that shows what is the total cost for X months?

3. Graph the cost of the cell phone plan, using months as the units of time. Be sure to label your axes and scale them by labeling each gridline with a number.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
