You bought a blu-ray that cost $28.68 before tax. How much did you have to pay once the 7% sales tax was factored in?

xxTIMURxx [149]

Answer:

You had to pay $30.69 after the sales tax factored in.

Step-by-step explanation:

First step is to find 7% of $28.68.

The answer to that is the sales tax, therefore making the sales tax $2.01.

Finally, you have to add $2.01 to $28.68 to get a total of $30.69, your final answer.

What is the perimeter of the figure?

Monica [59]

Hey there,

So when finding the perimeter, we do addition.

So . . .

20 + 12 + 18 + 7+ 13+6

Your correct answer would be 76

Hope this helps.

Remember
x^-m=1/(x^m)
u^-3=1/(u^3)
1/(u^3)=1/125
therefor
u^3=125
u=5

x=-3
easy
y=-3-13
y=-16
correct

normally, y is output
(x,y)
chose al second numbers
0,3 are all acceptable
B and D

y=mx+b
m=-3
y=-3x+b
sub point
(x,y)
(1,-2)
-2=-3(1)+b
-2=-3+b
1=b
y=-3x+1

remember (x,y) you keep swtiching those
