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.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
