Answer:
b = $48000, m = $3187.5 / year
Step-by-step explanation:
The equation of a linear function is given as y = mx + b, where m is the rate of change, b is the value of y when x = 0, y = dependent variable and x = dependent variable.
Given that V = mt + b:
b = initial price of the house at 0 years = $48000
V = mt + 48000, At 8 years the house is appraised at $73,500
73500 = 8m + 48000
8m = 73500 - 48000
8m = 25500
m = 3187.5
4x4=16
5x5=25
The area is between perfect squares 16 and 25. Then the side length is between 4 cm and 5 cm
Answer:
Yes
Step-by-step explanation:
(x-1)(x+1)(x-3i)(x+3i)
FOIL ( x-1) (x+1) = x^2 -x+x-1 = x^2 -1
FOIL (x-3i)(x+3i) = x^2 +3ix -3ix -9i^2 = x^2 -9(-1) = x^2 +9
(x-1)(x+1)(x-3i)(x+3i) = (x^2 -1) (x^2 +9)
FOIL again
x^4 +9x^2 -x^2 -9
x^2 +8x^2 -9
This is the factored form
