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.
Do you mean 5^2? its called 5 to the second power. Hope this answers your question! :)
Answer:
B
Step-by-step explanation:
<h2>—Math</h2>
–x/4 < 7
–x < 28
x > –28

The formula to find the x coordinate is -b/2a. If you plug in the variables
-5/2(2) = -5/4 = -1.25
x = -1.25
Now plug in x into the y equation.
y = <span>-11.125</span>
