Answer is A
<B = 90 but <D = 29
Answer:
A: initial value: $750; rare of change: $60
B: y = 60t + 750
Step-by-step explanation:
Initial value = value when he started ( in 2000) =$ 750
Each year he add a constants to that value
'y' will be the amount he get after t years a amount increase each year
y = 750 + at
In 2010 his free = 1350
t = 2010 - 2000 = 10 year
y = 1350
y = 750 + at
1350 = 750 + 10 a
600 = 10a
a = 60
y = 750 + 60t ( his fee as a function of time)
In slope form: y = 60t + 750
He increases he fee by $60 a year.
Answer:
x=0 x = 1/6
Step-by-step explanation:
5x -30x^2 = 0
Factor out the greatest common factor which is 5x
5x(1 -6x) =0
Use the zero product property
5x =0 and 1-6x =0
x =0 -6x = -1
x = -1/-6
x = 1/6
The second graph represents a constant speed of M miles per hour
Answer:
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 + 0.44x - 1.69x = 19
-1.25x = 19 - 24
-1.25x = -5
x = 4
