Answer:

27.83$  I believe

Step-by-step explanation:

30.09 is the end price, so multiply that times 7.5% or 0.075 in decimal terms

You would get 2.25675 which is the amount of tax that was paid

So all you have to left is subtract 2.25675 from 30.09 to find the original price

30.09-2.25675=27.83325

or 27.83 rounded to the nearest hundredth

5. What is the solution of |3x-3|_<18?
Mrrafil [7]
Answer : D

WORK...
|3x-3| \leq 18


PART 1:
3x-3 \leq 18
 add 3 on both sides... 3x \leq 21 divide by 3 on both sides... x \leq 7

PART 2:
3x-3 \geq -18  add 3 on both sides... 3x \geq -15
 divide 3 on both sides... x \geq -5

plug both answers together..
-5 \leq x \leq 7

The range of the function f(k) = k2 + 2k + 1 is {25, 64}. What is the function’s domain?
MAXImum [283]
<span>f(k) = k2 + 2k + 1 = (k+1)^2
The range is what the function gives to you f(k)=25=5^2 or (-5)^2
f(k)=64=8^2 or (-8)^2

You need to find the k values for these boundary values to find the domain. 
Good luck :)</span>
