Answer:
50 + 100n
Step-by-step explanation:
The cost is the cost of the visit plus the cost of the cavities
50 + 100n where n is the number of cavities
22,528 is 10% more of 20,480.
10% of 20,480 is 2,048
2,048 plus 20,480 is 22,528
Answer:
Step-by-step explanation:
p = kd/u
p varies directly with d, p=md
p varies inversely with u, p=n/u
put them together
p=kd/u
as d goes up, p goes up. as u goes up, p goes down
Your answer is y = 1/2x + 2. The slope formula is y = mx + b. To find the y-intercept, (b) you just look at where the line intercepts on the y-axis, which in your case it intersects at positive two. You can find the slope by using the rise over run formula. To get from point A to point B, the line rises up one on the graph, and "runs" over two, so the slope would be 1/2. Then we plug these numbers into the formula to get y = 1/2x + 2.
