Answer: $161.85
Step-by-step explanation: $220 is the original price. you want to first deduct the 30% tax. Find out the 30% tax by multiplying 220 x .30 = 66. So deduct the $66 from $220 to get $154. That is the price. You will need to add on the 5.1% tax. So to get the tax you multiply $154 by .051 to get $7.854. Add that to the $154 sales price to get a total of $161.854. But since money, you can't have a portion of a cent so you round the 4 down
Answer:
Step-by-step explanation:
Start by removing the brackets.
Left Brackets
30(1/2 x - 2)
30*1/2 x - 30*2
15x - 60
Right Bracket
40(3/4 y - 4)
40*3/4 y - 4*40
10*3 y - 160
30y - 160
Now put these 2 results together.
15x - 60 + 30y - 160 Combine the like terms.
15x + 30y - 220 That's one answer Others are possible.
5(3x + 6y - 44)
The answer is 9.2933587e+34
Answer: whas the Answer?
Step-by-step explanation:
Answer:
Inverse Function: f^-1(x) = 9/4x + 9
Step-by-step explanation:
To find the inverse function we can interchange the position of the variables x and y, and then solve for y;
y = 4/9x - 4 => x = 4/9y - 4,
x = 4/9y - 4,
4/9y = x + 4,
y = 9/4x + 9/4(4),
y = 9/4x + 9/ f^-1(x) = 9/4x + 9
