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
In total, you have 48 cents.
25+10+10+3= 48

Answer:
8 7
Step-by-step explanation:
15/10-8/10=7/10
Answer:
Standard form for straight line y = m x + b where m is slope
m' = -m or m * m' = -1
answer a or y = - 8/7 + 4 satisfies this requirement
Answer: 9d - 25 = 920
D= 105
step-by-step explanation:
9d - 25 = 920
+25 +25
9d = 945
•divide 945 by 9 and you should get 105
