Rosa is saving money for a trip. she has already saved 250$ and plans to save $40 per week. this situation can be represented by the function f(x)=250+40x, where x is the number of weeks. how much money has rosa saved after 6 weeks?

After 6 weeks Rosa has saved $490.

Step-by-step explanation:

1. You have the function given  in the problem above, where os the number of weeks:

2. Therefore, to solve this problem you only need to substitute 6 weeks (or ) into the given function, as following:

3. The result is $490.

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
