Answer:
f(6) ≈ 31
Step-by-step explanation:
If f(x) varies directly with x, we can write f(x) this way:
f(x) = kx
Using the given values, we can find k:
f(25) = k×25 = 130
k = 130/25 = 5.2
Then for x = 6, we have ...
f(x) = 5.2x
f(6) = 5.2×6 = 31.2
Rounded to the nearest whole number, ...
f(6) ≈ 31

Step-by-step explanation:
it will 2.5 this is right answer option D
You are given two points in the linear function. At time 0 years, the value is $3000. At time 4 years, the value is $250. This means you have points (0, 3000) and (4, 250). You need to find the equation of the line that passes through those two points.
y = mx + b
m = (y2 - y1)/(x2 - x1) = (3000 - 250)/(0 - 4) = 2750/(-4) = -687.5
Use point (0, 3000).
3000 = -687.5(0) + b
b = 3000
The equation is
y = -687.5x + 3000
Since we are using points (t, v) instead of (x, y), we have:
v = -687.5t + 3000
Answer: d. v = -687.50 t + 3,000
