Answer:
statement 'a' and 'b' are comparing two different things
Step-by-step explanation:
statement 'a' is referring to arriving at a selling price for at least one product
but, assuming the store sells more than one product then there is no correlation to the profit margin of the store as a whole
First to make the equation you need to make the ordered pairs that will come out to be (3,285) and (6,510)
Second you plug those ordered pairs in the slope formula, you will end with
510-285 225
-----------= -------- = 75 that's your slope
6-3 3
Now you plug it in the point slope form
y-285=75(x-3)
y-285=75x-225
+285 +285
-----------------------
y=75x+60 is your equation
f(x)=75x+60 in function notation
Part C: to graph the equation you can start off by making a table where you plug in -2,-1,0,1,2 into the equation for x or if you need to do more depends on your problem.Your labels for the x-axis would be the number of days and your y-axis would be the cost of rent after x number of days.
P: x + 2 = 9
x = 7 # Subtract 2 from both sides
E: q - 5 = 12
q = 17 # Add 5 to both sides
H: 6 + m = 27
m = 21 # Subtract 6 from both sides
Y: t - 14 = -3
t = 11 # Add 14 to both sides
J: u - 7.5 = 2.4
u = 9.9 # Add 7.5 to both sides
I: n + 7 = -20
n = -27 # Subtract 7 to both sides
G: d - 1 = -16
d = -15 # Add 1 to both sides
A: b - 40 = -25
b = 15 # Add 40 to both sides
M: 18 + w = 7
w = -11 # Subtract 18 from both sides
L: k + 8.3
k = 11.5 # Subtract 8.3 from both sides.
Answer:
for every x in the domain of f, f -1[f(x)] = x, and
for every x in the domain of f -1, f[f -1(x)] = x
