whole number are positive integers.
Answer: Choice A) $0.45
================================
Explanation:
Plug in d = 0 and you'll have A(d) = 0.45d+180 turn into A(0) = 180. This says that Terry is paid $180 even if he doesnt travel a single mile.
Now plug in d = 1. You should get A(1) = 180.45 as the result.
Subtract the results: 180.45 - 180 = 0.45
He has earned 45 cents or 0.45 dollars for traveling one mile
----------
A shortcut is to notice that the slope of the line is 0.45
It might help to view A(d) = 0.45d+180 as y = 0.45x+180. We see that the equation is in slope intercept form y = mx+b
m = slope = 0.45 tells us how much additional dollars Terry earns for each additional mile traveled
b = 180 = y intercept = starting amount of money Terry is paid, this amount does not change based on how many miles he travels.
Answer:
Step-by-step explanation:
top left r= 0.9 ; top right r= 0.4
bottom left r=0; bottom right r= -0.4
if they are not around a line looking like r=0
if they resemble a line well is close to r=1
if line goes up from left to right is r positive
if line goes down from left to right is r negative
16*35=560, I used multiplication
