Answer:
Since U is the midpoint of XY,
Answer:
y = -0.4 + c
Step-by-step explanation:
y = mx + c (original form)
m ⊥ - 1/m
2.5 = 25/10
25/10 ⊥ -10/25
-10/25 = -0.4
y = -0.4x + c
The function for the model that gives the future value of the investment in dollars after t years is: f(t) = 2000.e⁰·°⁴²t
Give, a lump sum of $2000 is invested at 4.2% compounded continuously.
Hence we have:
P = $2000
rate of interest = 4.2%
years = t
we know that A = Pe^rt
Substitute the above values in the formula.
Amount = f(t)
f(t) = 2000.e⁰·°⁴²t
hence we get the function for the model that gives the future value of the investment is f(t) = 2000.e⁰·°⁴²t
Therefore we get the required function.

Answer: y=-32
Step-by-step explanation:
1. Simplify:
-6y-90=-3y+6
2. Add like terms:
-96=3y
=> y=-32
