Answer:
a) y = 9x
b) For every increase of 1 hour the price to rent the lane increases by $9.
c) $27
Step-by-step explanation:
a) Since it costs $18 for 2 hours we can infer that for every 1 hour it costs $9.
So, the equation would look like this:
y = 9x
b) In this context, for every increase of 1 hour the price to rent the lane increases by $9. Like the question gave us, the price for 2 hours cost $18.
c) Plug 3 into the equation:
y = 9(3)
y = 27
Therefore, it costs $27 to rent the lane for 3 hours.

<u> 12x³ - 12x </u><u /> = 3/7 - 1/56x² - 3/7 = 3/7 - 3/7 - 1/56x² = -1/56x²

Answer:
a
Step-by-step explanation:
divide 9 and 6 each by 3 and bam you got a 2x3 poster
You just multiply 450 by .18 and it'll give you the 18% you have to add to 450.
So the equation would look like:
450(.18)=81
Which you then add:
450+81= 531
So 531 is your total!
