Let's begin by listing out the information given to us:
This is perpendicular to the line
The equation is already in the slope-intercept form:
The slope of the parallel line is given by:
We proceed by substituting the values of x & y into the new equation, we have:
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:
180° is galf a full turn, so it takes 1/2 less time that is 20 seconds
90° is 1/4 of a full turm (360°), so it will take (1,4)×40= 10 seconds
45° is 1/8 of 360, so it will take 5 seconds
270° IS 3/4 pf 360°, so the answer is (3/4)×40 = 30 seconds
X=4 just set up a porportion and solve
